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.

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 😭😭😭

Some of the players see them as Annoying critters,But they have a use...If you can kill a Jellyfish,I mean Cnidaria...U can get 10-12 biotoxin,Which is good,If u are taming a creature,When it's torpor goes down..We use nacrotics as solution...It increases 40-80 torpor...But a single bio toxin...It's increases 80-180 torpor thats insane...Because Nacrotics need 5 berries and a spoiled meat ..But if u kill a jelly fish u'll get many biotoxins that is equalient to many Nacrotics....U can kill them with basilosaur easily..and lure them to beach shore and killing them,But this method is risky,Because if u get close,They can give u a electronic punch that takes lot of health...I recommend using bow and crossbows for killing it...It's a friend and foe

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

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

These guys are annoying when i step in the water they attack and kill me. I know this jellyfish species its the deadly box jellyfish that that kills you in the ocean. Me and my carbonemys are swimming in the water to find dossiers and box jellyfish attack me and dies. 1 like= remove box jellyfish
