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.

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

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

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

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.

These trashbag demons killed my moshchops when I first started the game

I hate them more than compy

just swim to them (DON'T GET TOOO CLOSE) and then if they follow u swim back to the coast and if get can't get closer to u just shoot them

tadaaaaa u got biotoxin

Try taking out with a basilosaurus they are immune to the shock effect

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

Went on a killing spree with my spino to pass time to breed aga. Decided to go kill piranhas and my spino legit got stunlocked permanently until I finally managed to kill all of them with my spino hanging on by a thread because of these godforsaken things. Hunt these things into extinction or they'll murder everything you love and the neighbors.

If they are close to the beach lure to shore with crossbow and then kill them with a sword or spear once they beach themselves.

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.

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

My level 250 spino and I were enjoying the water and I didn’t know anything about these guys. Went for a nibble and got lit up. 5 megalodons came to reinforce my mistake and there I was, dead and without my beautiful spino.

Do not swim into the light…

Use a Basilosaurus, they are immune to the shocks from jellyfish and eels, also immune to tuso grabs. Easy biotoxin.

Remember when we thought they were friendlies...

These guys killed a my Carno less than 30 seconds after it was tamed. RIP Carno.

Guys I. Going to for a swim what a couple of jellyfish who cares they won't kill us. My brain said until we find out they make the oceon 9 times more annying

STAY AWAY FROM THESE they are FASTER THAN YOU THINK!

—I recommend staying at a safe distance and cross bowing them before they get to close to your Dino’s-

!Warning!:

nothing that isn’t resistant to them can survive an encounter with these. These monsters are GIGA KILLERS

Use the basilosaur to survive this menace
