Their attacks shock you (which makes you unable to move), and they often stick in groups. If you get surrounded by these, you're basically dead. Don't use melee weapons, use a crossbow.

They drop bio toxins, which can be used for a new tranq dart that's more powerful AND shocks the target.

Don’t have your spinos near them

I HATE These guys if you see one don’t even think about going into the water they are creatures that like the trodon that litreally STUN LOCK YOU UNTIL YOU DIE if you see one then there’s allways more I mean don’t even get me started on how many deaths I had to them in ARK mobile

They aren’t tamable because there so o.p, one killed my lvl 296 Rex🥲

Make these tameable so I can light up my pond 🐙

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

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 :(

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

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.
