WILD When I first discovered this ginormous jellyfish deep in one of the countless underwater caves, I couldn’t believe my eyes. Surrounded by smaller jellyfish this majestic creature shined with such brightness and beauty I almost fell in a trance. Once you take a closer look however, you can discover the metal ore, black pearls and even element crystals growing inside of it. If you are in the position to take one of these giants out, you will be rewarded with plenty resources, outstanding gear and some of the best blue prints to ever be discovered. However, this mission tends to be a lot harder than one could even imagine. Dealing with the electrifying cnidaria and the poisonous medusae is not an easy task but that is not where the battle ends since you are deep in the ocean and must defend your new found loot from anything that may would also like a split. TAMED Once tamed you can use your new found friend as a tool for long ocean discoveries. With unlimited oxygen, a handy boost, a radar for all surrounding threats and poison missiles, nobody should be able to challenge you. If anyone or anything does land a hit from up close, your poison will instantly come into play and help you get out of any sticky situation. The interior can be used a place to build any necessities for a long underwater trip or as a place to enjoy the deep ocean lights. Details When creating this concept the main idea was to help make the deep ocean world on the center feel more lively. We soon realized a new broken mosa killer wouldn’t really change much so we went and looked for different ways. Our favorite thought was to create raid like encounters with huge loot drops as an incentive to discover the deep depths since there is sadly no real reason to visit the beautiful water caves at the moment. However we also want you to enjoy the creature once you tamed it so we went back to the drawing board. Finally we decided to go with a huge jellyfish. So lets start with the wild one. I know nobody really likes the current jellyfish in the game but let me convince you that this one is different. First of all this much bigger cousin of the Cnidaria is not aggressive. But how can this thing be like a raid then? Easy. We can use the already existing ones to create a swarm like mechanic with the medusae in the middle as the queen. Once killed you can harvest the resources inside the jellyfish. However the big boi isn’t completely defenseless on his own. If you attack him in melee range you will get poisoned. The quantity and quality of loot depend on the level of the creature ranging from metal and flak armor to element and top of the notch blueprints. We hope this could be like a hot spot for amazing underwater fights in pvp while the players try to defend their new found loot. But how does the tamed ones affect the ocean life? Well, we tried really hard to create an amazing experience for pvp and pve players. Obviously for pvp players this will act as a mobile war machine with range attacks, a radar like the para offers, a lot of health and just generally it can act like an underwater station to prepare for raids since you build a small base inside your tame. For pve players the base aspect will probably be even more important. The “head” of the jellyfish is translucent so you can enjoy the beauty of underwater lights while not running the risk of drowning or getting attacked by vicious plesios. Every player can just build their nice little base and go on underwater adventures. Obviously it can spawn in different colors that all have their own amazing glow. We also thought about a tek saddle with new advanced features for both base building for pve and new Weapon options for pvp but this is a topic for another day Taming We would be happy to hear what you think about how to create the best possible taming experience. We thought baout the taming part a lot but we couldn't find something we liked so we would like to hear what you think about this. Building Inside the Essexella: The "floor" of the inner build space of the giant Jellyfish is relatively flat & can be built on without the need of foundations altough you theoraticly can place foundations & pillars and every other structure that fits the inner space of the Essexella the base floor of the Build space counts as a nfoudation and can be used to palce things like beds, Generators, smithys and nearly all other structures directly on the floor. The Size of the inner build space will be about 5x5 underwater Tek Compartments. Tek Saddle concept in the comments due to max file size! Bonus Concept Art: *This Post includes AI Generated Footage

Laminacaris L. sonusrex "Thin bladed shrimp sound king" Cambrian Diet: Durophagous Temperament: docile Within the oceans and beaches are piles of empty trilobite and Sea scorpion shells and this is the culprit, a vicious predator to anything with a chitinous shell, these bottom dwelling creatures seem docile near humans as they'll even swim around survivors to snatch up a bottom feeder and break its shell open with their facial appendages. Not even the beach is safe as these creatures can scuttle onto land in pursuit of their prey where they run them down and break their shells with deadly efficiency. Though they can be tamed, some tribes do hunt them as their bodies build up large amounts of oil and pearls that they ingest from their meals and thus brings an instant bounty of rare resources to some less fortunate tribes. Taming: To those who have passed out from Sea Scorpion venom, worry no more. These things hunt the stinging buggers from a distance, clicking and snapping their appendages like a pistol shrimp would its claws, stunning or killing anything it sees as prey. If tamed, these are perfect mounts to bring to the bottom of the sea to gather resources be it from animals or the environment. They can even be trained as their strikes are able to break stone and with consistent use they can become a menace to anything with an exoskeleton and potentially more. Some tribes who have tamed these animals have even been seen harassing Dunkleosteus away from their fishing grounds so to better gather materials in relative safety. Human blood has an interesting effect on these animals as it binds the individual animal to a master so to tame them, one must have scarlet pearls, Silica mixed with blood to lure them in and pacify them. (edited) [8:53 PM] Details Mountable tame though carried similarly to the Bloodstalker. Though can't be mounted on land but can in water like Diplocaulus Has a weaker stunning sonic snap.... a projectile of sound like a pistol shrimp Has a closer mele attack like a mantis shrimp that kills Sea Scorpions and Trilobites Can go on land and in water. has a harness that holds oil to allow for an ink cloud for quick getaways. Harvests and has a carry weight reduction for Black pearls, Silica pearls, and Oil. Has an ability to get better and better at harvesting one item depending on the item constantly harvested. Kill a lot of Sea Scorpions? Then it is gonna be great at getting Chitin and both pearls hitting oil? It is now the Oil baron.

The Tylosaurus was a giant mosasaurus being equaled to the mosasaurus in size, but this subspecies has very specific forms of attack. Wild: Unlike the mosasaur that lives in the depths, Tylosaurus sicarius lives closer to the shores looking for prey that is far away or that is on the surface when the prey is sighted you can see from afar a bang after the jump followed by a bite that if it does not kill the prey the bleeding will kill them they are solitary predators but they will be of great help. Taming method: To tame your own Tylosaurus you will need patience since you will have to look for a bigger Tylosaurus and make it retreat leaving it with 2% of the total life so you will find where the nursery is and be able to tame a baby with Kibble and only Kibble. Skills: Bite: Basic attack working with right click with good damage. Ambush: Hide with your Tylosaurus and attack prey while swimming to cause bleeding. Swing: Uses its tail to throw creatures smaller than a plesiosaur out of the water, this attack works on large ones but only deals damage. Push: In this attack, the Tylosaurus throws itself against the enemy and stuns it, giving time for ambushes or escapes. Thirst for Battle: Gives 20% bonus speed and 10% damage to allies. Saddles: Like its mosasaur relative, Tylosaurus has the normal and platform saddle with the platform saddle being slightly smaller than the mosasaur platform. Shallow Jump: In this attack, the tylosaurus will jump onto the beach or nearby rocks, dragging creatures smaller than a triceratops into the water. Dossier: the tylosaurus is a literal great addition to this marine giant's team, it is always ambushing the creatures, this mosasaur enemy lives in intermediate places between the deep and shallow and loves to attack rafts in the center so attention must be given to the sea survivors , his attacks are incredibly effective so make sure he doesn't miss your boat but don't settle for staying on the beach if this giant spots you he will jump onto the beach trying to get you dinner.

"Imagine a creature that combines three abilities of dinosaurs. Well, with the Isisaur, it is no longer imaginary. This creature combines the capabilities of the Spinosaurus, Basilosaurus, and Yutyrannus. It can resist jellyfish (which everyone loves) and can call different fish to protect and attack potential intruders in its territory. Moreover, it can assist you in fishing by attracting fish using a pheromone located in its fur. Another significant detail is that when it is in a group or a duo, they can destroy most structures, even up to stone, during their charge. So, be cautious about where you settle. The habitat of our dear friend is one of the most dangerous, namely the swamps and their surroundings. Therefore, you can well imagine that the Isisaur is not easily approachable. Speaking of which, its taming process is quite simple. You will need to perform dance emotes while approaching it and offer its favorite food, which is beer, of course. But be very careful; if it is not in the mood, it will let you know by shaking its neck. However, if by chance it appreciates your dance, it will slowly lower its head, and you can give it the beer. Please note that you will only have four chances to find the right emote; after that, it will attack you. Also, making a mistake in its appreciation won't decrease its effectiveness."

Name: Livyatan Species: Livyatan monstro Diet: Carnivore Temperament: Territorial but passive to humans Time: Miocene Wild Truly a sight to behold, Livytan monstro is the largest aquatic creature I’ve ever seen! It spends most of its days swimming about in the deepest depth of the ocean, rarely ever surfacing. When it does it’s usually to get fresh air and go right back down to continue its hunt. Its massive size does give it an advantage. It particularly uses its size against its favorite prey, Tusoteuthis. Despite its territorial nature, it seems content to have humans around it. As long as they dont attack it, they should be fine. Domesticated Those that have tamed Livyatan have found it to be a reliable mount. Its unique set of abilities at ones disposal makes it stand out among the arks underwater creatures. It appears to gain more strength when faced against its rival the Tuso. Riders are even granted protection from the ink it secretes when escaping. Furthermore, it can use its call to inspire its aquatic brethren, much like a Yuty, granting your aquatic tames vigor that they normally wouldnt be able to acquire. Whether by its sonar or general prescence, Megalodons seems to become afraid of this giant whale, seeming disorganized when in groups. Abilities Bite: a simple bite Tail smack: the whale will swing its tail at the attacker, knocking it back some. Inspiring Song: Livyatan can inspire its fellow aquatic tames! This grants them higher damage outputs and damage resistance. Disarming Sonar: functions similar to that of a Yutys fear roar scaring away many of oceans more annoying creatures. Blowhole: A stream of air relases from the top of its head. While this is purely for asthetic purposes you can use this similar to a Geyeser for parachute travel! Passive abilities Protection: riders and itself are granted protection from the attacks of the Tuso. Rivalry buff: in the presence of Tusos, Livyatan is granted a damage buff and reduction. this can be useful for hunting down squids! Shock Immunity: Livyatan is unaffected by the shocks of Cnidaria and Electrophorus. Meg Pack Disabled: being in their general vacinity, Livyatan is able to completely disable the pack buffs of Megalodons. this goes away when either the megs die or LIvyatan leaves. Taming: Taming Livyatan can be quite the task. If you approach mounted, the whale will think you’re coming to attack and be ready to fight! If you’re unmounted, the whale will curiously approach you. Should you have its favorite food, Tuso tentacles, it will graciously accept them! If you’re worried about it only eating Tuso tentacles after taming don’t worry! It can subside off Raw Meat and Raw Fish Meat! https://en.wikipedia.org/wiki/Livyatan

Species: Cameroceras Thalassapyro Time: Middle Ordivician Diet: Carnivore Temperament: Aggressive Wild Many survivors including myself have noted the extreme depth of the ocean on this Ark, apparently the western side of the ocean has no end but I seriously doubt if this is true. Many prehistoric marine life dwell in the strange abyss but one of them is significantly more flashier (fishier?) than the others, Cameroceras Thalassapyro. In a lot of ways it is similar to Tusoteuthis Vampyrus in that they are both cephalopods capable of spraying ink but that's where the similarities end for me at least. For one Cameroceras is much smaller that Tusoteuthis (I'd posit around the size of a Dunkleosteus) and well it glows and not just that, it's ink glows. Cameroceras ink seems to have many different properties depending on which colour the Cameroceras decides to glow and it can fire the ink in multiple different ways, either in a single big cloud similar to Tusoteuthis or multiple small bursts it can fire from a distance. Domesticated A tamed Cameroceras can prove to be one of the most useful underwater creatures to have at your (tribe's) disposal. Its large cone-like shell can be used as a big spear to just simply skewer other creatures but that's rarely why survivors tame them. The main reason Cameroceras Thalassapyro is tamed is due to its glowing ink that changes its properties depending on its colour, from what I have seen there are three "modes" Cameroceras can go into "heal" (green), "damage" (red), and "freeze (or just stun)" (cyan). What the ink does in these modes is pretty self-explanatory but as stated before Cameroceras can fire the ink in multiple ways either in a single large cloud or multiple small bursts that can be fired from a distance but I should warn you, Cameroceras is not an infinite well of ink, if too much ink is expelled it will have no ink in its body and will have to speed up its metabolism to make more ink, in non-biologist words when Cameroceras runs out of ink it gets incredibly hungry so make sure you brought a lot of snacks during your dives with this thing. Mechanics Cameroceras is the multi-purpose aquatic creature capable of stunning, dealing damage, and even healing things and its all because of its fancy glowing ink! Cameroceras' basic attacks include a bite and weird cone slam, similar to the Woolly Rhino you can turn this cone slam into a powerful charge attack though not as powerful as the Wooly Rhino's charge attack. Cameroceras can expel ink the same way in all of its modes either in single devastating cloud like the Tusoteuthis or it can fire pellets of the ink from a distance similar to a tek saddle. The three modes are heal (green), damage (red), and freeze (or stun) (cyan). Heal mode heals things that come in contact with the ink, Damage mode, get this, damages things that come in contact with the ink crazy right?, and lastly freeze mode stuns things that come in contact with the ink. Stun mode in particular deserves a somewhat deeper look, the ink bullets don't immediately stun enemies but only after many, many shots. The Single Ink Cloud does instantly stun enemies however. Cameroceras has a unique ink stat, this stat determines how much ink it can expel, when theres no more ink Cameroceras gets a status effect that increases ink replenishing however also making it's hunger drain a bit more. Taming Oops I forgot to add how you tame this thing, uuhhh you let it eat some honey i guess.

Dossier: Giant Olm (Genus: Megalotyphlus) Subject: Giant Olm (Megalotyphlus aberrans) Designation: Classified Attention, survivor! You are now reading a classified dossier on a remarkable creature known as the Giant Olm, native to the treacherous depths of the aberrant world. As an authorized explorer, you have the privilege of accessing this information. Please exercise caution and discretion while reviewing its contents. Description: The Giant Olm, a subspecies of the common Olm, is a colossal amphibian that roams the eerie subterranean caves of Aberration. This creature is an awe-inspiring sight, reaching tremendous sizes beyond anything witnessed before. It shares a similar appearance to its smaller counterpart, possessing a slender, elongated body with vestigial eyes and external gills. However, the Giant Olm is easily distinguishable by its exceptional size and the presence of sharp, jagged teeth. Adaptations: One of the most remarkable traits of the Giant Olm is its ability to produce a unique mucus that serves as a natural defense against the painful stings of the indigenous jellyfish. This mucus coats its entire body, providing a protective barrier. When slain, the creature will drop some of this mucus, which, when consumed, grants temporary immunity to jellyfish stings, a precious asset for any survivor traversing the perilous underwater environments of Aberration. Taming Method: Taming the Giant Olm requires great skill and strategic thinking. Survivors must venture deep into the cavernous realms, locating its lair within the murky depths. Once found, the process involves delicately luring the creature to the surface by using specialized bioluminescent bait, crafted from a combination of organic materials and rare resources. Only then can you initiate the taming process. Approach with extreme caution, as the Giant Olm is highly sensitive to disturbances and will defend itself ferociously. Utility: Once tamed, the Giant Olm becomes an invaluable asset to survivors exploring the hazardous underwater environments. With its colossal size and powerful jaws, it can effortlessly dispatch smaller aquatic threats, including dangerous predators like the Cnidaria. Additionally, survivors riding the Giant Olm can utilize its natural mucus to protect themselves from jellyfish stings, significantly reducing the risk of injury. This protective mucus, combined with its immense strength, make the Giant Olm an ideal companion for underwater expeditions and resource gathering. In the Wild: In its natural habitat, the Giant Olm is a solitary and elusive creature, rarely seen by surface-dwelling survivors. It prefers the murky depths of Aberration's subterranean cave systems, navigating the labyrinthine networks with uncanny grace. The Giant Olm preys on various subterranean creatures, feeding on smaller amphibians, fish, and invertebrates that venture near its domain. It is important to exercise extreme caution when approaching this creature, as it has developed acute senses and formidable defensive capabilities. Conclusion: The Giant Olm represents a fascinating addition to the aberrant ecosystem. Its massive size, ability to produce protective mucus, and proficiency in combat make it a highly sought-after companion for survivors venturing into Aberration's treacherous underworld. However, capturing and taming this awe-inspiring creature requires great skill, patience, and a keen understanding of its environment. Exercise caution, survivor, and may you forge a powerful bond with this colossal amphibian in your quest for survival. Taming Process: Taming the Giant Olm is a challenging endeavor that requires careful planning, resource gathering, and a steady hand. Follow the steps below to increase your chances of successfully taming this magnificent creature: Preparation: Before attempting to tame a Giant Olm, gather the necessary supplies. You will need: Bioluminescent Bait: Craft this special bait using a combination of organic materials such as fungal wood, aquatic mushrooms, and angler gel, along with rare resources found in the depths of Aberration. Scuba Gear: Equip yourself with reliable Scuba Gear to ensure extended underwater survival during the taming process. The underwater caves can be treacherous, and having the ability to breathe underwater will be invaluable. Locating the Giant Olm: Venture deep into the subterranean caves of Aberration, specifically targeting the areas known to be inhabited by the Giant Olm. These creatures typically dwell in the darkest and deepest sections of the cave systems. Be cautious of other dangerous inhabitants such as Nameless and Rock Drakes that may also populate these areas. Setting the Bait: Once you have located a suitable Giant Olm lair, set up a secure vantage point nearby. Carefully deploy the bioluminescent bait, making sure to position it where the creature can detect and be enticed by its luminescent glow. Remain patient and vigilant, as the taming process may take time. Initiating Taming: When the Giant Olm is drawn to the bait, it will cautiously approach the surface. It is crucial to remain calm and avoid any sudden movements that may startle or provoke the creature. Slowly approach the Giant Olm, offering it additional bait by hand, establishing trust and familiarity. Establishing Trust: Continue the process of feeding and bonding with the Giant Olm over an extended period. Show it patience, care, and respect, allowing the creature to become accustomed to your presence. This gradual trust-building process is crucial for a successful taming. Finalizing the Taming: Once a strong bond has been established, and the Giant Olm is comfortable with your presence, it is time to take the final step. Carefully mount the creature and secure your position, ready to embark on your underwater adventures together. Remember, the taming process can be dangerous, and any sudden movements or aggressive actions may result in the failure of taming or even a hostile response from the Giant Olm. Approach with caution, respect the creature's boundaries, and exercise patience and perseverance throughout the process. Good luck, survivor, in taming this remarkable giant of the depths. May you forge an unbreakable bond and unlock the incredible potential that the Giant Olm offers.

With all the features and creatures present in the oceans of Ark, most water bodies are quite empty, or have a lack of interesting fauna and floral biodiversity. A characteristic that my team and I hope will be implemented more into Ark 2 for aquatic environments, though for animals to be introduced to Ark. One taxonomic classification of animalia that is usually under-looked are crustaceans, with only the Karkinos being present in Ark on specific maps. For a new addition, why not a Carboniferous Period crustacean distantly related to Mantis Shrimp, crustaceans who have the fastest and strongest punches in the animal kingdom. For size purposes, most Mantis Shrimp are quite small with only a few species growing up to or around 40 cm's in length (specifically the species Lysiosquillina maculata), this fictional species will be quite larger than its early ancestors, both for adaptive radiation and biological purposes, and because about 80% of animals in Ark are oversized (common trend). Common Name: Aenigmacaris Species: Aenigmacaris tromeronychus Time: Early Carboniferous Diet: Omnivore (primarily Durophagous) Temperament: Territorial Tameable: Yes Rideable: Yes Breedable: Yes Torpidity Immune: No Taming Method: Knockout Preferred Kibble: Superior Preferred Food: Chitin Equipment: “Aenigmacaris Saddle” (Level 71 - Crafted at either a Smithy or an Argentavis saddle) Rider Weaponry: No Humans Can Carry: No https://www.thefossilforum.com/index.php?/collections-database/arthropods/crustaceans/aenigmacaris-cornigerum-schram-horner-1979-r88/ Wild "Lurking within crevices in the seafloor, Aenigmacaris tromeronychus is a gigantic species of proto-mantis shrimp that lurks in tropical and humid oceanic environments. Ranging from reefs to abrasion coasts, these crustaceans are more robust, aggressive and armoured than their Earth counterparts. Their most notable feature, the dactyl clubs on their raptorial appendages, have evolved chitinous plates and extensions of their exoskeleton that allow the mantis shrimp to strike at speeds faster than a bullet. Enough force to break through mollusk shells, the carapaces of trilobites and break bone in vertebrates''. Domesticated "Survivors who tame Aenigmacaris find that its specialised forearms, its eyes that are able to detect various wavelengths of light, its ability to block the attacks of foes with its telson, and its ability to turn and move at short-timed bursts quicker than a dime; makes this crustacean a perfect siege and shielding mount that can impact its surrounding habitat with the snap of its claws''. Anatomy Discovered originally and documented from 1978 to 1979 by Frederick Robert Schram and Jack Horner, the species Aenigmacaris cornigerum has been found throughout Montana, similar to other Aeschronectida crustaceans. However, Aenigmacaris has more characteristics prominent in this genus, and is considered more closely related to mantis shrimps or modern day Hoplocarida than other proto-genera. A. cornigerum was found in the Late Mississippian subperiod Bear Gulch Limestone, more specifically in the Heath Formation of Montana, while the species A. minima has been found in the Kinney Clay Pit or Kinney Brick Quarry, and the Late Pennsylvanian subperiod Madera Formation/Group both in the Manzanita Mountains of New Mexico. Not much has been documented about this genus, with these shrimp being on average, around 102 mms in length (the fictional species is around 5 ft in length and 4.7 to 5 ft at its thorax to antennae). Like most crustaceans in their taxonomic classification, they had a layered chitinous exoskeleton and were quite abundant in the fossil record in their given sites and formations. Aenigmacaris had the basic body plan of most Aeschronectida, that including 3 long flagellate antenna, an enlarged abdomen, a shortened thorax, 3 segmented thoracic protopods (appendages), cephalic kinesis, pleopodal epipodite gills, an articulated rostrum and their body plan being divided into four segments or tagmata (including a food-processing unit, the pleon (the abdomen of a crustacean) and tailfan (used in propulsion), the walking-appendages and the sensorial unit). The carapace of these crustaceans covers the entire thorax and their compound eyes are stalked on the anterior cephalon of the head. The paleoenvironment of the Late Mississippian Carboniferous Bear Gulch Lime in the Madera Group/Formation in Central Montana consisted of a variety of fauna and flora, such as the earliest Synziphosurina Anderella parva, different genera of shrimp such as Belotelson magister and Sairocaris centurion, Carboniferous Period Horseshoe crabs like Euproops, cephalopods (ammonites, nautiloids and coleoids), a wide array of worms (nematodes, bristle worms and ribbon worms), cartilaginous fish such as Belantsea montana, Debeerius ellefseni, Falcatus falcatus, Stethacanthus, Thrinacodus and Squatinactis montanus, Actinopterygians or ray-finned fish like Cyranorhis bergeraci and Discoserra pectinodon, and lobe-finned fish including early coelocanths. In the formations Aegnimacaris cornigerum specimens have been uncovered, many of these shrimp appear to have fed on small prey present in and around algal growths. Design While the original genus of Aenigmacaris lacked any presence of clubbed claws, the fictional restoration Aenigmacaris tromeronychus has features prominent with Holocene Mantis Shrimps, the only living ancestors that have the closest relations to these shrimp. For the design of this species, A. tromeronychus should have the base body plan of Aeschronectida crustaceans, such as Cragopsis socialis with features like the shield carapace over the thorax, its limb count, feeding appendages and telson: https://www.researchgate.net/figure/Crangopsis-socialis-Salter-1861-OM-B-13970-Partial-reconstruction-Note-the-upraised_fig5_277674538 For a colour pallet, the texture of the Aegnimacaris should vary amongst individuals, with some having bright patterns similar to a Peacock Mantis Shrimp (Odontodactylus scyllarus) https://en.wikipedia.org/wiki/Odontodactylus_scyllarus Or The Purple Spot Mantis Shrimp or Gonodactylus smithii https://lifg.australianmuseum.net.au/Group.html?groupId=I5dgCwCr And others might have more bland or camouflage-based colour pallets designed to blend in with the oceanic floor: Squilla Empussa https://ucmp.berkeley.edu/arthropoda/crustacea/malacostraca/eumalacostraca/royslist/species.php?name=s_empusa While having characteristics present with the original Aenigmacaris, the fictional species should have smasher-type or “clubbed” dactyl appendages to differentiate it from other mantis shrimp species, but would play as an evolutionary and advantageous adaptation for this crustacean’s survival in the harsh biosphere/ecosystem centred around Ark Survival Evolved. The tailfin and telson should contain a reinforced exoskeleton and plating in correlation with its abilities and defensive purpose. Abilities - Aenigmacaris can boil surrounding seawater through the use of their forelimbs, purposefully superheating and vaporising water with the spring of its club-like appendages. This behaviour present in mantis shrimps demonstrates how the intense velocity and momentum created from their claws can result in the production of cavitation bubbles and enough force to result in sonoluminescence. Creating a flash of light (which has a 10% of stunning prey - Stunning Ability) with temperatures warmer than 4000℃. Aenigmacaris can provide heat absorption and warmness insulation effects within a given designation around the crustacean towards nearby survivors, when in combat or spring-loading its claws (which can also boil, burn or deal thermal damage to enemies that are struck by its claws). - Aenigmacaris tromeronychus have a melee attack known as “Shockwave (Shochwaved when dealted to opponents)''. When the pressure in a cavitation bubble collapses due to a shift in said pressure and force from potential energy that increases in a surrounding water body, from the use of their raptorial claws. Modern day mantis shrimp can create “shockwaves' ' that can stun or kill prey. This physical ability could be implemented into this fictional species of Aegnimacaris. - Similar to the 450 different species of Earth mantis shrimp, the compound eyes of Aenigmacaris can detect the multiple wavelengths of the light spectrum, similar to humans, but can detect ultraviolet and polarised light. Allowing these crustaceans to detect and differentiate prey from the blue reflections and background of the continuous ocean depths. Granting the Aenigmacaris a visual enhancing ability that allows the crustacean to detect the slightest movement signals and disturbances in its surrounding environment. - Peacock Mantis Shrimp and other “Smasher-based or non-sparring appendage” Stomatopoda are known for their ability to break through glass and structures with the momentum of a 22. Calibre bullet, capable of easily devastating aquariums. If this was applied to a gigantic species, the potential energy released would be more impactful. Aenigmacaris have an applied buff known as “Splintered”. The longer a charged snap is held, the damage increases and can dent or immediately destroy or decrease the fortitude of foundations, structures and building materials depending on the set or material. - Aenigmacaris have a quick turning radius, though it requires a lot of stamina. - Based on the characteristics present in Aenigmacaris and other Aeschronectida, the carapace protects the thorax and the body parts connected to the head. Providing further safeguarding for vulnerable organs and weak points that can potentially be advantageous for predators. This exoskeleton plating or “shell” blocks about 80% of oncoming melee and range damage dealt to the head. - When in combat, both wild and tamed Aenigmacaris can fold their body’s inwards (in a foetal position) with their telson, tail plates and tailfin bending towards the body. Being able to absorb and deflect incoming melee damage with resistant and relatively thick armour plated or calcified cuticles along the tail that naturally protect mantis shrimp and Aenigmacaris during territorial telson sparring sessions. - Aenigmacaris will naturally hunt trilobites, ammonites, Eurypterid sea scorptions and small fish. While they don’t have a gathering or material collection boost, these crustaceans receive an experience point boost, similar to imprinting, though it applies to specific species of aquatic organisms. There is also a small chance (5%) of a buff known as “Triturate '', where the shells of marine arthropods decrease in defence and health recovery or natural regeneration when struck by a Aenigmacaris snap, breaking opposing shells in the process. - Knockout taming these organisms is a dangerous process. High-level wild Aenigmacaris can one shot survivors given the time and chance, which is why elasmosaurus and Dunkleosteus placoderms are recommended in distracting or degrading the armour and health of the Aenigmacaris to about 15%. Allowing the player to feed the mantis shrimp chitin or kibble (higher efficiency) every 5 to 10 minutes, with its health very slowly regenerating. This process will continue until the animal is tamed. - Present in most mantis shrimp species, both males and females are monogamous and will only have one specific mate throughout their entire lifespan. This creates trust bonds, and coordination/cooperation between the pair that can influence the stats of offspring Aenigmacaris and the imprinting process of larvae. Weaknesses - To balance out the abilities of the Aengimacaris, these crustaceans have a slower movement speed and swimming capabilities. Instead, adapted for a territorial, ambush-based and melee implemented niches/roles. - Aenigmacaris are weak to large or specialised oceanic predators, including Elasmosaurus (are able to manoeuvre and outpace the attacks of Aenigmacaris), Mosasaurs, Baryonyx (stun attack), Spinosaurus, Dunkleosteus (are able to break through the exoskeleton of Aenigmacaris and are not affected by about 75% of the defensive buffs and boosts applied by the Aenigmacaris) and Sarcosuchus (death roll and agility). - Mantis Shrimp and numerous different species of aquatic crustaceans can survive out of water for a given time, though Aenigmacaris have a unique metre that monitors their moisture levels from surrounding influences. Temperature, climate, humidity and weather can affect stress levels and the conditions that allow these crustaceans to survive outside of water. - Based on studies on Peacock Mantis Shrimp (Odontodactylus scyllarus) The snapping of the dactyl clubs on the forearms of a mantis shrimp decreases their overall force, momentum and velocity when outside of a water source. Punching at an estimated half variable/percentage approximately speed-wise when in the presence of air, when compared to water. This applies to Aenigmacaris where melee damage is debuffed by a percentage of 50% or (½) outside of saltwater. - Aenigmacaris larvae are very feeble and infirm, being a potential prey source to numerous predatory organisms including cnidaria, electrophorus, megalodons, mantas and megapiranhas. Increasing the requirements/demands essential to raising and breeding these crustaceans. Any suggestions and comments please reply below. This is still a work in process.

Umoonasaurus Common name: Umoonasaurus Species: Umoonasaurus demoscyllus Group: Reptile Time: Late Cretaceous Diet: Carnivore Temperament: Docile Habitat: Ocean (Mostly found near the colder regions of the Ark) Wild Happily frolicking along the cold seas of the Ark is a plesiosaur of small stature called a Umoonasaurus, it has a notable crest made of keratin on its head which is much larger than its real world counterpart. Like its relatives the Umoonasaurus tends to reside in the deepest parts of the ocean feasting on its favorite food: the Ammonite. While I was watching the Umoonasaurus attack Ammonites I have noticed that it doesn't get attacked by other creatures while eating, it seems to delicately chew through the shell of the Ammonite by extracting the bile and not letting a single drop of it to leak from its mouth. Domesticated Umoonasaurus doesn't need a saddle to be ridden but can still be crafted to help provide the creature with protection, it also allows the rider to use weapons while riding it. It is a fast ocean mount able to outspeed even an Icthyosaurus, but the speed comes at a cost. It can dart through the water at high speeds but only in short bursts because its stamina drains too quickly when sprinting. Umoonasaurus is an adept bile gatherer and can also harvest pearls on the sea floor making it an invaluable tame in the oceans of the Ark. Taming Method: Umoonasaurus has to be passively fed Ammonite Bile but doing so will not attract any unwanted attention as creatures tend to ignore the Umoonasaurus when its feeding on Ammonite. The only problem in the taming process is that the Umoonasaurus is quite a playful creature and will want you to chase it after being fed. Its a fast creature to chase so bringing an Icthyosaurus is recommended, the Umoonasaurus only slows down when it wants to be fed again. Abilities: Mounted Bite - Harvests meat, silica pearl, black pearl and large amounts of ammonite bile. Whirlpool - Rapidly spins in a circle, knocking back and damaging nearby creatures hit. Dash - Lunges forward, covering a large distance and damages creatures in its path. It consumes a lot of stamina when used. Passive Keratin Armor - The keratin covering its head provides natural armor and reduces incoming damage taken from the front. The Umoonasaurus doesn't take reduced damage when attacked from the back and its sides. Ammonite Hunter - Deals increased damage towards Ammonites and harvests large amounts of bile from each kill. Has a higher chance of obtaining silica pearls and black pearls when harvesting the Ammonite's body, creatures ignore you when you attack an Ammonite. Insulation - Provides the rider with insulation but its effect is much weaker compared to a Basilosaurus. Credit to Johan Egerkrans for the used artwork.

Common Name: Odobenocetops Species: Odobenocetops chalithalasus Time: Late Miocene to Early Pliocene Period Diet: Bottom Feeder (Molluscivore & Vermivore - Invertivore) Temperament: Curious Tameable: Yes Rideable: Yes Breedable: Yes Torpidity Immune: No Taming Method: Passive Preferred Kibble: Superior Preferred Food: Chitin Equipment: “Odobenocetops Saddle” (Level 58 - Crafted at either a Smithy or on an Argentavis saddle) Rider Weaponry: No Humans Can Carry: No https://en.wikipedia.org/wiki/Odobenocetops#/media/File:Odobenocetops.jpg Wild “Being the top predator of the invertebrate fauna amongst the ocean floor, Odobenocetops chalithalasus is a medium sized (15 ft long) subspecies of tusked Delphinoidea cetacean that thrives along the seabeds of tropical and temperate oceans. Unlike basilosaurus and other whales, Odobenocetops are equipped with a pair of unique asymmetrical tusks that contain millions of nerve endings, which allows these whales to detect the slightest movement, change or occurrence in their environment. A major adaptation and biological characteristic that has led to their success as the island’s main aquatic molluscivore, and of whom will occasionally hunt trilobites and small cephalopods. Using its broad teeth and tongue to crush their shells apart and syphon out their slimy insides”. Domesticated “Like its ancestors, Odobenocetops is incredibly social, curious and shares many distinct behaviours with beluga whales, primarily their elaborate social bonds and the formation of pods that discourages the slightest temptations of the carnivorous fauna that line the open sea. The same behaviour is shared with oceanic tribes, of whom use these animals in the hunting and gathering of sea scorpions, pearls from clams and the elimination of shelled pests, but also the deterrence of mantas, megalodons and the occasional cnidaria that line the seaways”. Anatomy Discovered in 1993 (by Christian de Muizon) in Southern Peru in the Pisco Formation, and later Chile, the genus Odobenocetops is a family of cetaceans that belongs to the superfamily of toothed whales known as Delphinoidea. While considered closely related to Narwhals and Belugas (Monodontidae), porpoises (Phocoenidae) and Albireonidae (an extinct monotype family of porpoise-like toothed whales) since 2014; this clade of tusked whales lived from the Tortonian of the Late Miocene, to the Zanclean of the Pliocene. The paleoenvironment of Odobenocetops in the Pisco Formation of Peru consisted of a biodiverse oceanic environment, with a wide variety of animalia, flora and species. Cetaceans including Odobenocetops were quite frequent with Livyatan melvillei (macroraptorial physeteroid), Acrophyseter (a smaller macroraptorial sperm whale), Atocetus iquensis (a small Miocene toothed whale), Balaenoptera siberi (an early baleen whale), Brujadelphis ankylorostris (an early species of river delphind) and Hemisyntrachelus oligodon (an early genus of Orcininae dolphins) being found at this site (presenting just a handful of the whales found in this location). The formation also contained pinnipeds (seals, sea lions, walruses) such as Acrophoca longirostirus and Piscophoca pacifica, birds such as Pelagornis, pelicans and Spheniscus penguins, the semi-aquatic marine sloth Thalassocnus, Piscogavialis jugaliperforatus (a monospecific genus of “gryposuchine gavialid crocodylian” related to the gharial) and the large prehistoric shark Otodus megalodon. When looking at Odobenocetops’s anatomy, the first characteristic is its tusks. While the tusks are quite brittle in shape or design, the tusks are prominent in males, where this genus experienced a form of sexual dimorphism between males and females. In a male specimen of O. leptodon, the right tusk measured around 1.2 metres or 3.9 ft in length, and the left tusk measured about 25 centimetres or 9.8 inches in length. This difference in size among tusks is currently considered controversial in the paleontological community, as assuming all males of this species and/or genus had asymmetrical tusk lengths is currently unknown (but will be applied to this fictional subspecies in Ark). These tusks or enlarged teeth are speculated to have been a product of convergent evolution similar to narwhals (the difference is that male narwhal tusks develop from the left maxilla or the upper jaw bone, where as male Odobenocetops tusks are implanted in the right premaxilla or the small cranial bones at the very tip of the upper jaw in most animals) and pinnipeds such as walruses, with many stating that these tusks were special sensory organs to help detect invertebrates in the sand or in the animal’s surroundings. When comparing this characteristic to narwhals, their tusks are filled with nerve-rich connective tissues (and about 10 million nerve endings) that creates a “pulp” that acts very similar to the enamel of human teeth, specifically when a tooth become sensitive when presented with cold, acidic or environmental conditions (or substances). This pulp allows the whale to detect the slightest changes in its surroundings, including salinity or salt levels, temperature, the proximity of nearby prey sources and can even support navigation. There also are secondary speculative details connected to the purpose of the tusks in Odobenocetops, ranging from courtship rights, use in intraspecific competition (Jousting amongst males) or sexual selection and/or for territorial purposes. Below are two specimens of Odobenocetops tusks, from both species: https://commons.wikimedia.org/wiki/File:Odobenocetops_peruvianus_5_maf.JPG https://en.wikipedia.org/wiki/Odobenocetops#/media/File:Odobenocetops_leptodon_4_maf.JPG The skull of Odobenocetops leptodon and Odobenocetops peruvianus contain an exact presence or reduction of a melon, a mass of specialised adipose tissue or body fat found in the forehead of all toothed whales. The melon’s function is that it modulates the animal’s vocalisations, acting as a sound lens that is important in communication and echolocation. The orbit or the cavity of the eye socket in the skull is “deeply notched” in Odobenocetops peruvianus that suggests binocular vision (the other species O. leptodon instead has an anterior edge that is slightly concave in shape). The palate of the skull is arched and toothless similar to that in walruses, and with a broad snout, flexible neck able to articulate over 90 degrees and a length of 2.1 metres or 6.9 ft in length (with a weight between 150 and 650 kg’s), Odobenocetops is speculated to have a diet as a bottom feeder. Feeding off of any (invertebrates) small worms, mollusks and thin-shelled bivalves in its habitat, using its powerful tongue to pry open and suck the foot and /or siphon of these mollusks out of their shells (ejecting the shell in the process). Skull of a female specimen of Odobenocetops peruvianus. https://en.wikipedia.org/wiki/Odobenocetops#/media/File:Odobenocetops_peruvianus_female.JPG Design When looking at the animals that classify as “related” clades and families to Odobenocetops, one major detail would be in the subspecies’s design. Odobenocetops chalithalasus has a natural countershading that provides camouflage from above or below, a characteristic prominent in porpoises, narwhals, belugas and other dolphins/delphinidae. This texture palette should also vary depending on its location, with members of O chalithalasus having paler skin tones in colder waters, darker colours in deeper waters and more “shaded” tones in tropical or shallow environments. Odobenoetops should have a blowhole that connects to its behaviour (applies to wild and tamed individuals) and an oxygen stat towards surfacing or “breaching”. https://www.ecomare.nl/en/in-depth/reading-material/animals/porpoises/ An example of the Odobenocetops’s natural colourization, in relation to a Harbour Porpoise. https://www.nationalgeographic.com/animals/mammals/facts/narwhal An example of the Odobenocetops’s colder biome colourization, based on narwhals and beluga whales. Abilities and Advantages - Odobenocetops chalithalasus has the presence of a melon like its ancestor O. leptodon, which grants it an echolocation ability (similar to Desmodus) that allows the species to detect the slightest changes in its environment, specifically the movement of other creatures (giving specific outlines towards predator and prey sources). Odobenocetops also has specialised hearing anatomy similar to belugas and narwhals, that can detect the slightest calls and/or movements of other animals, structures or survivors. - The tusks of Odobenocetops allow the creature to detect the slightest shift in climate (temperature) and allows the animal to detect the movements of creatures behind or to the sides of the cetacean. These tusks also allow the Odobenocetops a “fortitude” effect to specific attacks, decreasing the damage and stunning ability of Cnidaria, baryonyx and electrophorus by 25%, this percentage also applies to the chance of escaping a tusoteuthis tentacle grasp, slightly similar in ability to basilosaurus. - Odobenocetops have an insulation effect on survivors. - Wild Odobenocetops males use their tusks in sexual display and in certain circumstances, such as territorial “jousting” which in tamed Odobenocetops (has a 25% occurrence in the proximity of other males), increases the amount of damage the male performs for about 5 minutes in an ability known as “Sparring”. Attack damage and knockback damage is increased by 5%, movement speed by 5% and for 1 minute, a reduction of narcotic effects by 25%. In this process, wild males can also have a 50% chance of becoming “protective”, shifting their temperament when in the presence of females and will defend their pods from predators and survivors. An adaptation that allows the species to avoid or surpass predation. - Odobenocetops are incredibly social and curious animals and will allow a 5% XP boost and imprinting boost to other tames and a 10% to other tamed Odobenocetops. Female Odobenocetops increase this stat by 5% each (10% to other tames, and 15% to other Odobenocetops). - The strong teeth and broad snout adaptations peculiar to Odobenocetops grants it a 75% increased attack damage to all aquatic invertebrates, this includes ammonites, tusoteuthis, trilobites, eurypterid, karkinos and cnidaria. The Odobenocetops also has a 40% increase in gathering and 5% reduction in oil, chitin, pearls, black pearls (10% increase instead), ammonite bile (5% increase instead) and tusoteuthis beaks in an ability known as “Mollusca Specialist”. - The main predator of Odobenocetops in its environment was the giant Lamniformes shark, Otodus megalodon (or simply Megalodon). When in the presence of a megalodon, Odobenocetops will receive a defence and damage reduction status as a form of a natural deterrence and an adaptation from an environmental or predatory pressure that will allow a higher percentage of reflected damage onto its opponent (s). In pods, this effect is multiplied by 2% to 5% (depending on the pod’s individual levels) that affects this status, known/referred to as “Carcharodon Resistance”. - Odobenocetops chalithalasus have binocular vision which increases the rider/player’s visibility underwater. - Odobenocetops have incredible muscular flexibility and the ability to “turn on the dime” without wasting much stamina. - Odobenocetops can receive an additional secondary boost when in the presence of another cetacean, this being Basilosaurus solatiumfecit that grants a form of natural protection for these smaller cetaceans. - The tusks and side of Odobenocetops can be lightly dragged along the sand which can be used to detect creatures or objects in or around that area (this is also an ability that correlates to our Websteroprion suggestion). Weaknesses - Odobenocetops are mammals (and while the basilosaurus primarily lacks an oxygen metre); this cetacean should require an oxygen stat that very slowly gradually decreases the longer it is underwater (which should connect to a natural behaviour of breaching and diving). - Odobenocetops has a very specific diet focused around invertebrates and will not eat fish meat or mutton (basic meat and chitin are its preferred food choices). - While Odobenocetops doesn’t have “tons” of health and can protect itself from smaller to medium sized aquatic predators, mosasaurus, plesiosaurus, spinosaurus and sarcosuchus can quickly outpower an alone Odobenocetops. Specific Drops When killed, the Odobenocetops can be harvested for a small amount of oil from its melon or can slowly produce and store about 20 “Odobeno” oil. Rather than being used as a simple fuel type (not as efficient and productive for gasoline as basilosaurus oil), Odobenocetops oil can be used instead as bait for fishing lures in attracting coelacanths, piranhas, sabertooth salmon and lamprey. Odobenocetops can also drop blubber. For its tusks, the tusks can be used as a trophy or miscellaneous item, however we are still deciding on an actual purpose for this hypothetical item.

Name: Brygmophyseter Species: Sperm Whale Time: Pliocene and Earlier Diet: Meat/Fish meat Temperament: Aggressive Length: 7 meters - 12 meter Favourite food: Raw Prime Fish The Brygmophyseter is part of a group of macroraptorial sperm whales (often shortened to "raptorial") which tended to be apex predators using their large teeth to catch struggling prey such as whales. It had a spermaceti organ which was probably used for biosonar like in the modern sperm whale. But unlike modern sperm whales the Brygmophyseter would of been a pack hunter like the modern day orca. Brygmophyseter likely preyed upon a variety of animals including fish, giant squid, and cetacean and even Megalodon. Taming: Knockout Domesticated: Domesticated Brygmophyseter would benefit from a pack boost that would increase damage dealt and decreased damaged received. Generating ambergris inside the inventory. Platform saddle could be implemented due to the sheer size of these creatures. Ability's: Bite attack. Head ramming to cause damage to the potential enemies and structures. Due to being relatives of the sperm whale family.You could implement sonar that would stun enemies for a short period of time. With a cooldown so it isn't overpowered OR it could scan for potential enemies like a parasaur. Pros: Would be a viable creature to take on the aquatic boss. Cons: Could implement a oxygen timer to be refilled via surfacing. Only affecting domesticated Brygmophyseter. Sourced used : https://en.m.wikipedia.org/wiki/Brygmophyseter

Dossier Text: "Wild: In the bogs and marshes of the Island, one can find the serpentine Cymbospondylus paludraco lazing around in the water. This basal ichthyosaur will defend its territory aggressively, often going toe to flipper with sarcosuchus and even megalodons. Cymbospondylus seem to enjoy feeding on crustaceans and occasionally small fish. It can even crawl onto land for short periods of time. Domesticated: Tamed Cymbospondylus can be a worthy companion for tribes due to their incredible versatility. A tamed cymbospondylus can crawl onto land for short periods of time to fight or flee from danger, or even to ambush unsuspecting tribes. Furthermore, Cymbospondylus can grab small dinos and drag them underwater to meet a murky demise." Silly words: My concept for this cymbospondylus was of a versatile sorta amphibious ichthyosaur that would be fun to use and also good for both pve and pvp. on the pve front, cymbospondylus is powerful enough to rival tusoteuthis and most swamp creatures, and on the pvp front it can grab things like a kapro and also does 1.5x damage to bugs, so it can be a good counter to karkinos soakers. I also just wanted to have one in the game because they looked cool lol REMINDER: Do not vote on this for just the abilities, because WC is likely to change them! (dossier by yours truly)
