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

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 😭😭😭😭😭

U can still hit them when u get stunned

Bro was like weeping angels being able to yeet you off your tame unto the other side of the map. I was riding my mosasaur with a structure on its platform saddle just cruising my way to the base until one of this suckers bump my tame, then goes up up and away then died from falling.

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.

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

Do not get in the water with a tame without wiping these things out to extinction. They move silently and stun you and your creature so you can't move or fight back. Typically you can just stand on the edge of the beach, they will come for you, you can hop out of the water when they're close and then just whack them

Looking at the wrong page dude

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

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

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.

People have been telling me how these things killed there pets so when I see one or more I kill them all and harvest them

Only the basilosaurus can take it without getting knocked off.

I got my high level mosasaur killed because I got knocked off and

An alpha mosasaur killed it.

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.

It will kill your Dino they have super long agro range I was swimming in a turtle trying to gather oil but the jelly fish killed it rip frank

Who added these? Like come on? Who was in charge of making these?
