OMG!! Some of these guys came up to my angler fish and started attacking it out of nowhere!! Then my Sarco Swam in and started attacking them!! I thought they would both be dead BUT THEY SURVIVED!!!!!

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.

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...

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.

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

I’ve lost so many tames to these. They need to be fixed to where they don’t kill everything that touches the water excepting the basilosaurus. Logically, how does this dumb blue jellyfish kill spinos, mosas, plesios, and any apex predator that comes near? Just voicing my thoughts… hit the arrows if I’m not the only one who thinks this needs to change.

I think that the devs need to reconsider some of the creatures in ark. With the jellies and electrophorus, it's too much. Especially on fjordur. There are hundreds of eels EVERYWHERE in the shallows! I don't mean reconsider as removal, but they need to be nerfed. No person I know tames mosas, plessies, or dunkies anymore because of those two creatures. They've made a lot of ocean creatures irrelevant. My first water creature is always a basilo. And that's all I need, because what's the point of anything else.
