Ok, so I was once taking a swim while my tames were near the shore and when I look to my right, these guys showed up and I swam for my life but the shocked me so when I took my spear out and hit one of them my tamed came over and started to attack these jellyfish...

I lost my Scorpion, Parasaur, and Sacro. :(

R.I.P. Scorpio, Lilly, and Snapper...

These dumb gelatinous orbs killed: my sarco Rip daverwaver, my 125 Baryonyx Rip Bary the 1st, my Meg Rip Megan, and my pelagornis! Rip pelvis, please do kill these things on sight with a crossbow! For Valhalla and our dead mounts!

WORST THING IN THE GAME!!!!!! They will stun your tame and kill it, regardless of the level. Only the basilasaurus is safe. If they sneak up on you with your mosasuar, they will kill you and the mosasaur

Once I saw this thing in the water and I was like “ oOh I Didn’T KnOw TherE WeRe TreASure chEstS In tHIs gaMe “ and just ran like Usain bolt into them. I’d say it was more insane Bolt. And Bolted to the spot was I! Yep, my discovery of the Cnidaria!

Use the basilosaur, it’s not affected by the jellyfish it’s ability

I rather fight 5 gigas than these things, thats because they are stronger than 5 gigas! Whatever you do, dont step on the water, they are aggresive and can silently sneak up on you and stun lock you. First, look in the water to see if there are any, then if there is, Shoot all of them with a ranged weapon. Then you're done.

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.

Was trying to take care of an alpha Megalodon that kept attacking anything that set foot in the water near my base. As soon as I went in with my Sarco that I had literally built for killing this thing, 5 of these pulled up and ended it instantly. DEATH TO ALL JELLIES

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

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

U can still hit them when u get stunned

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

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

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

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

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.

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

Buy Titanfall 2

We neeeeeed more SUPPORT

(And more players)

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.

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