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.

Touch it and die!!! I learned that the hard way

In early game they are the must annoying water creature ever, to kill them you need to bring them to the nearest point from beach land then kill them with arrows and if melee weapon so be fair as possible to be save from these annoyers

Up this if you hate cnidarias I lost my spino to three of these in an instant

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

Kill on sight. Wipe these obscenities off the face of the earth.

So I’m taking a dip in the sea, see three megalodons and whistle my lvl 215 spino that I obtained at a very early level to attack them. This spino is my prize… the Apple of my Ark eye. Anyway, I see three idiot blue jellies WAY FAR AWAY rise up to attack my spino. My spino is just circling the megs and trying to kill them. Little does it know that an electric death awaits it. I sat there in horror, sure that my beautiful spino would die, but(and it is a huge and relieving but), my spino kills the megs just in time, and comes to shore. I ended up getting some biotoxin at the end of the trip, too! All good. BUT BE CAREFUL THEY WILL KILL YOUR LEVEL 215 SPINO. I’ve lost many tames already. The only reason I’m telling you guys this is because there is hope. Good luck, fellow survivors🫡

Me and my friend: *enters the water to move our 3 gigas off of herbi island onto the mainland*

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

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