You can bully them with a Basilo a good tip for people who absolutely hate this thing

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

Basilasaurus is pretty much immune to these guys attacks.

The only good from these little monsters, is harvesting the Bio Toxin from them to keep taming Dino’s unconscious.

These are just better narcotics in mobile

Because the ocean is really dark during the night, I decided to trap these guys in a stone railing box cage , so now I have a luminating water source if I go swimming.

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

You can't tame these creatures, but you can harvest their biotoxin after killing. Biotoxin is super useful for keeping a creature unconscious when taming. You can harvest about 12 from each Cnidaria.

Update Idea for this jelly boi: Since they don’t have eyes, ears, or even a nose form that matter so they swim aimlessly and can’t see where there going, they glow brightly at night time or in deeper water, they are smaller, weaker and stun lock doesn’t last very long, each individual jelly boi killed overs 3-5 bio-toxin but they wander in big groups. I hope the devs can take this into consideration, R.I.P. to the people who lost there dinos to these guys.
