I found an invincible one:( :( :(

If you sea glowing in the sea do not go to it

Me goes to glowing

Fieind do not go

Me goes anyway

Me dies a slow and shocking death

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.

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!

BROOO I WAS USING AGRY TO KILL THESE AND ONE WENT IN THE AIR AND HIT MY AGRY

Killed my beloved sarco Crocodile Dan whil i was getting oil, very fast silent untill they have yiu trapped

says it’s early game? I heavily disagree with that and they might kill a giga given the right circumstances

Ubfoot so can see..

I get water and fill my waterskin next 3 surround me and kill me and all my assisting Dinos :(

BASILOSAURS ARE IMMUNE TO THESE MF STING ATKS AND DISMOUNTS,UP SO THE NOOBS CAN SEE

Most annoying aquatic creature.

Cnidaria have a very large aggro range. They can't move very fast but you'd be surprised how've often they'll appear right behind you while you're in your inventory. Without a basilo, I kill them with my crossbow. NEVER look at a group of jellies and think, "Eh, they're far away enough. I can get into my inventory"

Lure them to near the surface and kill them from land.

For the new players if you see this thing in the water DONT APPROACH IT IF YOU GO NEAR IT IT WILL KILL YOU AND DONT BRING YOUR PETS NEAR THEM I LOST MY ARMY OF DILOS 2 CARBO 2 TRIKE 3 RAPTOR AND MY SACRO FROM THESE THING JUST DONT GO NEAR IT IT SWIM VERY FAST

Bary? Avoid.

Megaloshark? Avoid.

Spino? Ehh, he can nip at them but I wouldn't risk my buddy.

Basil? OH, IT'S GO TIME BABY.

These things dismounted me off of my 261 mosasaur and then killed me. I tried to go back and whistle the moss but it was stunned and couldn't move so it died instead.

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

These f!ckers killed ma spino and I destroyed em with a king titan

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.

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...

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