Never go near it with your Dino, it will kill you, your Dino, your friends, your family, the guy down the street, some guy over in Africa, all while they won't do a thing to attack it.

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.

To say like many before me (ahem)

If you are reading this it seems your underwater adventure came to a shocking conclusion.

Admit it. if you're reading this you definitely lost at least a dino or two to these guys.
