It sits there like an eerie ghost. Waiting. Waiting. and waiting...

Ark has a kill 250 dodo quest on mobile… why don’t they have one for these demons? One Like=one person who wants there to be a kill 1,000 Cnidaria quest. Also they killed my first turtle my sarco and almost my spino I have been gathering amber to revive my sarco.

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

Don't, just don't. These plastic bags are only slightly malevolent.

These things will follow you to the end of the earth. For bio toxin harvesting, I like to build a pen in the water to lead them into then hit them with a longneck or shotty from the shore.

U can still hit them when u get stunned

These guys are why you don't get attached to your critters.

To kill these guys, make them follow you to a shore and poke at them with a metal pike from where they can’t reach you.

I'm fairly New to ark and I was breeding Rex's on herbivore island and wanted to bring them to the main land but I didn't have a big boat able to carry the Rex's so I decided to take a swim there Rex's I thought there invincible I thought I was wrong

Rip omega bravo punisher and Becky 😭😭😭😭😭

These guys are the spawn of satan. Don’t go anywhere near them

I need to take an rex, looks like I'm out of shocking bullets...

Jelly bois: *chuckles* I'm in danger

Jelly bois after I get there, for no reason: *chuckles* YÕÜR ÏÑ DÅÑGËR

So, I tamed a mosasaur after that I encountered THESE monsters known as Cnidaria. Here’s a little tip if it throws you off your mount swim down and kill the jellyfish

Why are you even here? They are untamable1!2!2!2!1!1!!1!1!1!1!

Looking at the wrong page dude

I dunno if this is mobile only or very common, but I tend to kill these funky, shiny, plastic bags of death by luring them to the shore, then entering and exiting the water repeatedly until they get beached.

The only creature you’ve really got to hate. Admit it, you lost a Baryonyx or a Megalodon to this, “thing”…

Use your basilosaurus to get free biotoxin, they don't get close enough to kill u, ur friends, ur family

Complete ASSHOLES

They will kill you off faster than the Shining, and the can also paralyze your Dino and you. I wouldn't use a water Dino, I'd find one, check if any others are there, and then I'd use Crossbow and good tranqs.

To kill a Cnidaria, you first need to stay distant from it. Your materials needed are simple, a ranged weapon (Bow, crossbow, gun ECT. Plus lots of ammunition for the weapon. Next you will need to scan the water. Check for piranhas and other predators: IF THEY ARE NOT NEAR YOU CAN BEGIN. First enter the water. Next get close enough till the Cnidaria starts to come. They are slow and with enough speed you can get away. Slowly bring it towards the land/sand. It will try and follow you, since the sand is inclined it can’t come up. You may then start to shoot it in the head (to kill it faster). That is how to kill Cnidarias. If this helps PLEASE up this. Thank you!

Yes they are dangerous, but if you use a pike you can float near enough to dmg and or kill, they are usually fragile, but if not you can aggro to shallows and shoot with rifles etc...

I love these suckers on the island for the ease of access to biotoxins.

They are shocking and will stun lock and kill in groups one alone is manageable it stuns mount, you pike or arrow till it dies or visa versa.
