If cnidaria killing your dino, you can kill them by harpoon launchers

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.

Keep a far distance from these things snipe them from a distance, they will come after you and camp at the beach you ran on to get away they killed my bary seaweed and my spino mintchocochip. If you see groups of them form kill them off when you can

This is the kind of creature I'd happily hunt to extinction...

Evil Jellyfish Of Doom: "So You Have Chosen Death"

Real story 😭 1 👆 = 1 R.I.P for chaos , grim and nebula 😭😭😭

i threw a spear at a group of these guys, then my sarco went to kill them and I watched in horror as she flew through the air dead, now all I do is kill every last one of these guys

“this is the kind of creature I’d happily hunt to extinction”

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