these guys arent something to play with. they are slow tho so if you are on like barynox you could snipe them and they have really low hp and also always keep your distance if they touch your tame and it isnt ammune to its shock consider your dino dead.

raise this tip so noobies dont lose their level max tame like me:)

If u have a basilasouris u can delete it

Murder machines for early and most late game players they poison paralyze everything they need to be nerfed

While your tame still might die anyway if you have a high hp dino that gets zapped by these whistle followall and swim away. If you can i managed to rescue my 140 rex that way. She had 8k health and lost around half with a normal saddle. I came back with my re and killed them with rock throw. (It was super effective)

Me die

A helpful tip should include more words

It wants to cuddle with you. It won't stop till it touches you

I like to swim, bait this troublemakers to the ground, and shoot them with arrows from above ground.

Now how do you like ‘advantage’? You little sh*ts.

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

Basilosaurus. That’s all I’ve got to say

play on scorched earth OR extinction to never see this f***

One time, me and my brother were fighting a alpha megalodon with my two sarco’s, and suddenly, a whole MESS of these things attacked us and dismounted us and killed us all. It was a sad day in ark history. 😭

Up to 15 tentacles grow from each corner of the bell and can reach 10 feet in length. Each tentacle has about 5,000 stinging cells, which are triggered not by touch but by the presence of a chemical on the outer layer of its prey.

I will kill them from distance with a crossbow,to kill these you have to aim up on these and aslo these guys has so much less health they will die before they even approach you,but if u didn't see these then that is tha last moment for u or your tame. I hope this is usefull

You have entered the Encountering category? I have 3 words for you.

KILL

THEM

ALL

Just grab a shot gun and just blast them out of existence

can NOT be killed by therizno.

So I’m taking a dip in the sea, see three megalodons and whistle my lvl 215 spino that I obtained at a very early level to attack them. This spino is my prize… the Apple of my Ark eye. Anyway, I see three idiot blue jellies WAY FAR AWAY rise up to attack my spino. My spino is just circling the megs and trying to kill them. Little does it know that an electric death awaits it. I sat there in horror, sure that my beautiful spino would die, but(and it is a huge and relieving but), my spino kills the megs just in time, and comes to shore. I ended up getting some biotoxin at the end of the trip, too! All good. BUT BE CAREFUL THEY WILL KILL YOUR LEVEL 215 SPINO. I’ve lost many tames already. The only reason I’m telling you guys this is because there is hope. Good luck, fellow survivors🫡

Only fight them close to the bank. Get them angry and dash to shore. Then, stay out of reach of their electric tentacles and hit with a weapon. Make sure they are close to shore enough so you can stand.

Afterwards, harvest the Cnidaria's potent Biotoxin!

Kill on sight. VERY NOT FRIENDLY. They will totally obliterate you, your tame, your tames tame, your tames babies... they will even float up out of the water to attack your flyers. Ok that's not real but they're freaking ridiculous.

Don't recommend swimming close unless you have a Basilasaurus, lost my favorite itchyasaurus, her name was flipper , but I learned if you ride a raft, you can get close and stab with spear, easy removal of killer jellyfish.
