So this guy is supposed to be the ultimate organic polymer harvester, fast on water, slow on land, a slightly below average speed attacker that does a lot of damage, usually stays in groups up to 6 and also a good way to keep yourself warm, also the males have a mane while females don't, and they are smelly, anyways let's move onto the attacks:
Classic Bite: 40 dmg, harvests a good amount of polymer
Strong bite: 70 dmg and a bleed, has a 10 second cooldown and harvests an epic ton of organic polymer
Tail attack: 20 dmg, is faster underwater and slows the enemy down for 1 second
Scent: it gives you a buff that de-aggroes most creatures for 15 seconds and gives a debuff to creatures nearby that makes them 20% slower
Pack Buff Roar (Male Only): buff lasts 1 minute, it gives 20% speed, 20% damage, 20% resistance and 20% attack speed
Time to move onto a more specific description (not exactly a dossier because I am not good at making them):
Species: Thalassoleon Mexicanus
Time: Miocene and early Pliocene
Diet: piscivore/carnivore
Temperament: Male: Aggressive Female: Neutral
Wild: This Walrus usually lives in groups from 2 to 6, if anyone is attacked the entire group will protect the one who was attacked and try to kill the offender, Females are shy and will run away if attackes while Males are aggressive and you need to be more careful with them as they can easily kill you
Taming: To tame one you need to use a beartrap or a net ammunition and trap them, then feed them food, their kibble is the Superior one and they prefer fish over meat, but they will also accept meat if they need to eat it in order to survive
Tamed: These guys are able to not only defend you but with their teeth they are able to easily farm hide, pelt, organic polymer and more, their fighting strenght excels when they are in group as they become, faster stronger and tankier, and with their teeth they are able to bleed down even the toughest of the beasts, and this makes them really good to defend yourself underwater and also fight your enemies, and if you ever get in to trouble you can always leave your Thalassoleon's scent on the enemy and you will be able to escape
I will further improve this if I think of any good idea or if you guys give me some good ideas
Here is the drawing I made for it (It kinda sucks ngl)
