Basically no utility except biotoxin, only go after them with weapons that have long ranges and MAKE SURE YOUR TAMES WON’T CHASE THEM!!! When I was a noob I watched my entire dilo pack run after them and watched as they were all slowly and brutally murdered, and I’ll probably lose more tames to those monsters later. If a troll was a creature, it would probably be this one. One ☝️ = one RIP for every tame lost to these.

You cannot tame a jelly fish but you can kill it and use it's wonderful biotoxins as narcotics to tame other huge animals

Basilosaurus is the by far the best way to kill these things. Doesn't get shocked. High level ones harvest hundreds of biotoxin in minutes with no threat.

Once grabbed they won't let go till dead I had a Lvl 215 spino and was having a jolly swim then BANG WAM I get jumped by 8 jelly bastards and the spino died :(

When it says a 50% death risk with your fist idk if its talking about the jelly fish or you

The most overpowered creature i've met

For those of yous that play on console do this.If u lose ur Dino to something close the application straight away and go back onto ark your Dino will b safe and you will b back where the game last saved which won’t b as soon as soon as your Dino died hope this helps🙏

i remember one time i shot the jelly with a crossbow and it tried to get me so i ran away and i was fast enough to get on land but then the jelly got to the surface ( bcoz it tried to get me ) and died.i have just avenged my diplo 1 up = 1 rip for barnie

Let's hope there not in ark 2 they end a lot of early gamers careers

Basilasaurus is pretty much immune to these guys attacks.

Step 1: Tame a basilosaurus

Step 2: Equip a saddle on it

Step 3: MURDER EVERY JELLY YOU FIND AND AVENGE YOUR FALLEN TAMES!!! SHOW THEM WHAT IT’S LIKE TO DIE WITHOUT BEING ABLE TO FIGHT BACK!!!

These guys are annoying when i step in the water they attack and kill me. I know this jellyfish species its the deadly box jellyfish that that kills you in the ocean. Me and my carbonemys are swimming in the water to find dossiers and box jellyfish attack me and dies. 1 like= remove box jellyfish

These things killed my ichthy once😢 pls pray for every tame killed by one of these monsters🪦💔

"won't attack unless approached" is a LIE. These things are the ones who approach ME, and then they swarm me. If theres any body of water with them I have to IMMEDIATELY get out of there.

Dosent matter if u have any big dino avoid these and please kill then and take revange for my spino rex sacro and rhyniogantha

You and ur sarco: Oh look, a pretty lightshow.

Jelly dude: Hehehe

You and ur sarco: lets step in to check it out

Jelly dude: >:)

You and ur sarco: this is nice-AHHHH NOOO

Ark: you were killed by a cnidaria.

Ark: your sarco was killed by a cnidaria

You: noooooo

HOW TO COUNTER THESE LITTLE SH*TS! First off the archelon which is that huge turtle, the archelon is very strong and immune to the Cnidaria attacks, and is great for farming bio toxin. Second the baryonyx, specifically the spin attack, these shred the cnidarias, the only downside of this is if they shock the baryonyx you get stunned and fall off it, so just hope he’s strong enough to kill them on his own. THIRD, THERE IS NO THIRD 😭😭

KILL THEM! EACH AND EVERYONE!

Ummm funny story so I just tamed a titan ok and I decide to swim back to my base with it and I see these things an I thought they wouldn't do anything but.... it got my titan and after 5 hours of trying to escape it killed my titan his name was Billy

1 like = 1 respect for billy

easy kill if you use a raft and crossbow
