amphibian PLATYHYSTRIX: A sailed little oddball with poisonous mutating Slime




Real Life Context

The Platyhistrix 'Platyhistrix Rugosus' Is a small Temnospondyl that lived in the Permian 300mya, Temnospondyls were early amphibians and are related to beasts like Koolosuchas and Diplocaulus. It is primarily known for its unusual sail, similar to Dimetrodon or Spinosaurus although it is not closely related to either and its purpose is just as mysterious. Its back was covered by hard scute like plates but it has been identified as a true amphibian so may have been moist and smooth skinned like modern amphibians. In its hey-day it could be found throughout the USA in habitats similar to lush floodplains or marshlands which was crucial since like modern amphibians they are thought to be reproductively tied to the water and go through a tadpole metamorphosis phase like modern frogs and salamanders.


Should the 'Platy' join the ARK ecosystem, it would resemble a small Dimetrodon with the body of a Lystrosaurus with a large frog-like head with big yellow eyes, a bright blue tongue splayed out clawless legs and a long salamander like body with a medium length yet stumpy tail (see image above) It also possess the iconic sail, unlike Dimetrodon it is taller in comparison to its flat body and resembles a bright sea shell. It would have 4 main color regions. It is a small creature, not big enough to ride probably a bit larger than a bulb dog (see image above) It could be small enough to be a shoulder pet but could just as easily work without being a shoulder pet. They would often be found naturally in bright colors similar to a poison dart frog.

region 0: Stomach/shell lines

region 1: Body

region 2: Sail body

region 3: Back spots/scutes

region 4: N.A

region 5: N.A


The Platy would move in a crawling salamander motion, swaying its body will it walks, it would be able to run but not efficiently, it would probably run as quick as a bulbdog if not quicker. It would be as quick in the water as on land, still able to get around at a decent speed but not quick enough to escape some water predators like Piranna's


Sound designs, it wouldn't make much sound, maybe the sounds of bubbling or creatures gulping for air in a bit of a chirping medium to high pitch. Maybe some low grumbling included but nothing too grotesque.


Platy is a low tear predator, and would eat meat just like any carnivore, In the wild It would be a passive predator similar to Dimetrodon, it would not attack other animals or survivors aside from its special features (SEE MORE INFO BELOW), instead It would be skittish similar to Mesopithicus. It would be an uncommon find, not rare but not as common as say a dodo, but to find one that hasn't been attacked by another creature is another endevour, they would be solitary and spawn alone but you could find 2 that have blundered into each-others range by pure chance.


In Game Meta


Being a small creature, a survivor is not able to ride it, but it could be used as a shoulder pet. It would have generally low stats as shoulder pets do, low weight and health, but a dump stat would be for a Platy as designed in this post would be mainly stamina and oxygen despite being semi aquatic it would still need oxygen. In game meta, it would be a cute little utility tame, useful for all kinds of tribes, from low tear to alpha tribes. 


Like other amphibians like Beezlebufo and Diplocaulus, it would only reproduce in water, the eggs would have to stay underwater and the babies would hatch as tadpoles before becoming adults as they mature.

Poisonous defense

The Platy is designed to appear poisonous, with bright colors warding off 'potential predators' inspirations taken from Blue tongue lizards and Poison dart frogs. The mechanic built around its design involves its defense. When attacked or startled, it would release poison in a gaseous form, possibly similar to a lymantria or an Ammonite, I personally would akin the ability to a walking mushroom from Abberation, with the small portable spore-field inducing similar dizzy, health/oxygen draining and increased Torpor in tames and players. These could be deposited in areas like Lymantria for a short time or (I like more) form a protective bubble around the Platy as it flees from danger following it wherever it goes, this would make a startled platy potentially dangerous to any survivor or wild creature unprepared. Additionally, a creature biting a Platy or harvesting a dead Platy could induce this same sensation so dino's eating a Platy similar to getting hit with a Cnideria or something, so best beware, unless the player was protected by a hazard suit or gas mask, harvesting a dead Platy could be dangerous but would be rewarded with biotoxin, hard to get outside of Cnideria in the standard META.

Taming Method

The Platy would be a PASSIVE tame, but a challenging Passive tame, but still doable for even new ARK players. The taming food of a platy would be specific, something poisonous like bio toxin or organic polymer. Like any normal passive, you would feed it its taming food and wait until its hungry, but it would release its poisonous gas/spores even if its not startled. During the taming process and will not stop emitting these spores until either the taming bar is at 0% or when the taming process is completed. This needs to be mitigated with a gas mask or hazard protection suit giving use to the otherwise unused gas mask if you haven't learned the hazard suit engram from Aberration.

Tamed Utility

The Platy is undeniably a useful creature for all tribes, even the most powerful Alpha tribes would find Platy's useful. The Platy would first be able to release the poision on command at the cost of stamina, making stamina an important stat to boost. A tamed Platy would not be toxic to tames and ally survivors. However it would still induce the poisonous effect to other creatures and enemy survivors should it be startled or commanded to do so. If this was a shoulder pet, this combo could be devastating in pvp as you would become a walking sporefield as long as the staminia lasts, but easily prevented with protective gear like hazard suits or gas masks. in PVE if the torpor induce is powerful enough it could be used for KO-ing other tames or allowing for a getaway should you find yourself biting off more than you can chew, this makes it good for low to middle tear tribes at least combat wise, but still valuble in certain situation should higher tear survivors decide to use it, its basically a renewable poison grenade.


Harvesting them and taming them are both ideal for a survivor, obviously getting past its poison defense, harvesting a Platy would provide Biotoxin along with some hide and meat, Biotoxin otherwise is hard to come by aside from harvesting from Cnideria, making them a good source of Bio-toxin for players not as confident in the seas or in a location where Cnideria don't spawn very often. It also creates the dilemma of obtaining the bio toxin to tame it, (break a few eggs to make an omelet situation lol)

Mutating Toxin

The most important part of the Platy (its MAIN STAT and should really be considered if bringing it in) is the mutation factor. Having a Platy around for breeding its a GAME CHANGER especially for console players like myself who are unable to get MOD's that add items like the TEK mutator. To put it simply, if a tamed Platy is in range of creatures during the breeding process (2 creatures mating before gestation starts), it can pretty much double the likelihood of random mutation. This could take the form of a buff similar to the Oviraptor and would only be applied if the Tamed Platy was releasing its poison (again at the cost of staminia) in range. This utility makes it valuable to all tribes basic or alpha that are trying to breed the best creatures possible in their arsenal. Im no developer but this would really be a useful stat and save some really frustrating time trying to breed dinos with mutations for days on end.

Possible Uses

- Its got these big dumb eyes, big smile, and a cute lil blue tongue DILO wouldn't you want one around. YES they would probably be able to wear hats

- Biotoxin farm - its a good way to get Bio-toxin without venturing into the oceans, although Biotoxin is still best harvested from Cnideria

- PVP, they are walking spore fields, and poison grenades to creatures and enemy players if they are unprepared for them it could be a deadly combo for 1v1 PVP or when raiding a base, putting unprepared foes at a massive disadvantage, they are also a challenge in the wild to change, making them difficult to tame, but not too difficult since they are easily countered by obtaining Hazard gear, a gas mask, or if a player with no gear just runs in sacrificing their stats, hopefully re-spawning before it gets too far away 😧

- Breeding, these would be a game changer in regards to breeding random mutations at least in the current meta WITHOUT MODS, which is hard enough as it is. It would really benefit players of all types, those just starting out, experienced players trying to get the best mutations on their tames, or people just wanting dinosaurs with insane color variations. Having one of these guys around would really save a player trouble.

- Adding variation - another amphibian in the game would be interesting (I say as a lover of Beezlebufo and Diplocaulus) the breeding mechanics and mechanics I suggested above would make for a very interesting creature indeed.
