In ARK: SURVIVAL EVOLVED MOBILE, these guys can also make oily ink like the tusoteuthis(I am not sure with the other arks though). Refinable too already. Need not taming a tusoteuthis anymore ‘cause this guy does that work. Got one named Dolphy and he produces oily ink every few minutes. Max stack is probably only 29.
A great beginner tame, once you have an icthyosaurus, you can swim up to it and passive tame it. I just tamed one, and less than 5 minutes after I tamed a level 4, it’s killed 2 megalodons and 4 mantas. Like so noobs and beach bobs can see.
Good fighter, immune to jellies, supernatural healing boost at the surface, produces oil in its inventory, impervious to squid grabs, looks kinda cute too, only one bad thing about it: it gets squashed in the deep! Only slowly but the damage is there!
