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.

these guys arent something to play with. they are slow tho so if you are on like barynox you could snipe them and they have really low hp and also always keep your distance if they touch your tame and it isnt ammune to its shock consider your dino dead.

raise this tip so noobies dont lose their level max tame like me:)

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

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.

Here’s a massive tip that I’ve learned that I find helpful and you might or might not. I’ve found out that setting my tames on creatures like paras next to the sea is the worst idea, they will run into the sea and your tames will follow. I have lost tons of raptors, paras, Ankys and even Rex’s to these stupid jelly fish and there’s nothing I can do but watch. I play on mobile evolved so my experience might be different to yours.

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.

"Deepest parts of the ocean" yeah right! You run into these guys on the surface.
