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.

Make these tameable so I can light up my pond 🐙

Get in the water and give it anime body pillow then you can go in the water any time without a problem

You can forcetame this bad boy.sadly you can't ride them

Early game it’s easy to kite them onshore and harvest the bodies for biotoxin, which makes taming other creatures much easier

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 :(

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.

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