You can farm Biotoxin from these using Basilosaurus as it is immune to it's stuns therefore doesn't jake damage from them at all

Basilasaurus is pretty much immune to these guys attacks.

In easy zone one, (and probably anywhere else near ocean) can be farmed for their bitcoin, a more potent form of narcotic, used in shocking trang darts or just to keep dinosaurs sleepy

Very easy to kill. Primitive bow takes 4 or 5 arrows. Instead if grinding narcotic, hunt down this and harvest their bodies. They give you something called bio toxin which is used as a narcotic. Cant make arrows out of it, but its surprisingly BETTER than normal narcotics

Me: hey bro what up?
Bro: nothing just goin for a swim wanna come?
Me: sure but aren’t that jellyfish dangerous?
Bro: nah they fine come on!
Me: okey dokey!

Two weeks later: Me: hey bro did you complete making that chitin armour that got broke by that $&#*!?$&#* JELLYFISH?!!?

I wouldn’t recommend going after these guys unless you have some kind of bow. Once you do get a bow, shoot them from a distance where they can’t get you and shooting them is easy, you can walk up to their bodies once you kill them, take your arrows back and harvest it, but if there’s more than one I would get them all before taking the arrows/harvesting.

These guys drop bio toxin which CAN BE MADE INTO TOXICANT ARROWS AND AFTER A FEW MORE LEVELS SHOCKING TRANQ DARTS.

Use normal narcs for arrows. Use what these guys drop for KEEPING WHAT YOU ARE TRYING TO TAME DOWN...(gives 80 torpor to knocked out creatures)

It was the nice old days, back at my lovely peaceful river. Only Coelacanths, and a couple of Trilobites. Ahh the nice days, until a jellyfish came. Go for a swim I thought, it will be fun I thought, maybe I will take my Sarco. And so, I went for a swim with my Sarco and what happened?

P.S. KILL EVERYONE OF THESE I WILL GIVE YOU A NICKEL EVERY ONE YOU KILL

I lost a bronto to like 2 of these
