Cnidaria is a very powerful threat, Melee is impossible, Killing it is possible with ranged attacks, Velonsaur Darts, Any firearm, And The Wyvern Breath Attacks, And if you do choose to flee they are quite fast, Against a player with out Oxygen pumped they need to be quick to swim away. On a dino that swims fast they can be easy to bump into, So watch Out

Whenevere I see these guys I do a giga chad move,lute them and kill em with my sword I will avenge my old tames who have died to it and many more soldiers who has bad their tames killed my these monsters,I will them with ease and avenge me and you all people never give up and to kill these,you can't kill them with a:raptor strategy:get a little close to them and lure them into the most far place they can go into the land,n.2:kill them with your ranged attack(note they have bad range) this works better with a trike and Carno and many more big dinos like gigas and rexes,idk if I made your day better or worst but let me know by clicking the arrow pointing the sky mboby thingy,but if it made you dinos die click the downy button note again:I have lost 8 dinos/tames to this monster and I'm gonna avenge their deaths and yours.

Don’t go near these creatures just shoot them.

This thing killed my turtle named Michael Angelo

Ich can one tap these and make their drops better

A level 30 Cnidaria just killed me and my beelzebufo and I llost all of my armor and guns so from now on I am gonna kill all of these jerks on sight.

It's pretty easy just shoot it with bow or slingshot or lead it near shore and then use melee weapon

So I was killing that huge turtle kinda thing with my 9 dylos it when Tinto the water then there were 8 rip

I was killing a raptor, what I didn’t know was that it was going to turn into a disaster. At the time I didn’t have Dododex. I had like 19 raptors, 2 dodos, 4 trikes and carbies. Before I know it I lost 8 raptors.

These jelly’s stun lock you which makes you unable to move however you can still hit these jelly’s, and never go in the water near them they act idle but as soon as your in the water they creep up and you and boom your stun locked

Description is way off!

It is a big jellyfish found everywhere that will do what it can to mek your life miserable or end.

They are quite OP, but not very fast, but once you get close to them, you can’t get out, especially if there are more than one

U should have a harpoon if u want to kill it

If you’re just returning to ARK, what’s that glowing thing by coast? Chooses your next spawn location.

basilasaurs are immune to their sting

Basilo all the way! They don’t get shocked so just swim up and start munching

Lost my 160 plesiosaur to a group of these. Was following another plesi trying to tame it. These came and knocked me off and stun locked my Dino. The other plesi came over and killed us both. Be careful!

I am honestly scared to go in the water. I was chasing a Moschops and went in a river. A jelly spawned on me and killed me in seconds.

If you see them on a beach in early game get a bow and arrow's shoot the sh.t out of them and you'll have some bio toxin for a tame.

Monsters, with black hearts and no soul. You find one staring in your eyes (does it have eyes) and you feel cold. It killed Raptorsaurus II AND my sarco, Sarco I. Kill them, the resources are useful for taming and just do it. It’s suicide or homicide. Pick wisely. Raptorsaurus II and three of my dilos were on my raft while I was doing the task “Grand Voyage”. We pass a sarco eating some parasaurs and fighting dinos. I’m like, “oh, it can’t see me. I’m fine.” The sarco finishes eating, then swims at me and my tames. It gets on my boat, and my tames fight it into the water—I know, it sounds like it’s about sarcos, but listen—. It says “your Raptorsaurus II killed a sarco I’m like “yay!”. Cnidaria—3—get here, I’m like, “oh cheezewater.” I see that my tames are dying so I rush into water to help. “Your Raptorsaurus II has been killed by Cnidaria. I am so raged I kill the jellyfish. I was so sad that I left my three dilos to rot. I found them 8 months after.
