Guys the best way to kill these guys is

Go in water and get out and they will comme to you

Get them near shore

After that go in water again and come out

These dumbos will follow u on land and die

(This worked for me on mobile)

The only use they have is bio toxin it's better than narcotics

I'm Tiger and press the trang arrow attacking the dimmorphodon if u like it and to help newbies

TAME BASILOSAURUS!! They do not affect the Basi at all whether you’re using it as your mount or a follow tame. If mount tame you won’t be shocked or knocked off while killing or if follow tame use it to kill them so they don’t kill you and whatever Dino you’re mounted on.

P.S. just incase so I’m thorough and not misleading any “noobs” or beginners to tame the Basi it’s a “passive tame” or “non-violent” so taming it does not involve knocking it out. Tame an Itchyosaurus(also passive tame but they don’t try to attack you) once you tame the Itchy use it to tame the Basi otherwise the Basi will attack you

Actually nvm keep this jelly boi the way he is

Update idea: make them evolve into the common and harmless moon jellyfish :3

Be sure to be on land when you see these guys, they have long range vision.

Also, NEVER EVER use melee, just ranged, these jellyfish are sure a nuisance but give bio toxin which is basically the narcotic twice its stats

If you’re in the water without a tame, as long as it’s shallow backpedaling is almost fast enough to outrun these suckers. Although their stun renders you unable to move, you can still stab it, and they’re squishy.

Shoot it from the shore with a bow and arrow

I HATE THEM,so I abuse them with my good ol' shotgun.Also I used them for some dodo Science.

Use a crossbow or harpoon launcher for these guys melee will kill you

I lost a space dolphin to jellyfish this says enough if you think you can just go by them in a hurry don’t just take the time to go a different way

They aren't that bad if you kill it with a crossbow or another ranged weapon. You can hit the body after it's dead with a melee weapon or tool and you wont get stunned.

DEFINITELY DO NOT GO NEAR THESE, now there is a story:

My friend was having fun with his new rifle, then he jumped on one of his sarcos (he has 3 :D) and went underwater, one of these stupid creatures just pulled him OUT of the sarco and literally surrounded him, he killed them all but drowned, he was going to lose all his stuff, if you see these just kill them from land or DO NOT GO NEAR THEM

"Early Game"?!? go tell that to my dead sarco, gatorade. more like endgame for you. These are endgame not early game.

U can eat stuff when ur stunned by them

Mega turtle and Kark should be immune to jelly sting because some turtles are immune to the stings and some crabs are too.

A Basilo is pretty much the only way to deal with these since they are immune to the shock

Lost my Plesio on six of them so i tested with two high level Dunleos. Worked well just 10% health lost... The dinos are short time not stunned, so they can attack them. More dinos less care about them! Never swimm alone!They will get you :)

If you want bio toxin , lure them to the upper surface and drive over them with a raft, kill them and get that bio toxin

I nearly lost my 3000 attack lvl 500 shadow mane too these guys so always have a backup

I once saw some glowing stuff near seashore I said are these energy thingies but on I came closer it was Cnidaria and I tried killing them but they killed me and my dodo at least I got and dilophasaur now
