I’ve been playing ARK Mobile for a while, and I’ve learned that these guys biotoxin is pretty legendary. it is 100% needed in order to tame any high level creatures. simple way to kill them is pure them near the shore, and use a bow or gun to finish them off. occasionally they do happen to float ashore and die almost instantaneously, but that sometimes happens. but honestly, I promise, what they drop is legendary and you need it to get good tames e.i. Giga, griffin, quetzal
If a cnidaria killed my spino, boy i would be mad. i lost my sarco to cnidarias, a scare with my icthy with cnidarias, and almost got my megalceros killed by some. ( he is dead now D:) I kill any of these that i can. The dossier says that they are passive, but aggresive when approched, NO! as soon as i step in the water these attack, and they litterally don't move at all, they just sit there and chill until you or a tame steps in the water. one like=one prayer for my deceased sarco, Gatorade (you can find his story in sarco) and one member of the cnidaria hate club.
