Here are choice to kill these pest

1. Long neck rifle

2. Any gun

3. A spear

4.sword 50% death

5 and any range weapon

The long neck rifle is the best choice lots of damage a range weapon and fast

Easy to kill with a Basi and the bio toxin they drop is needed to make shock darts which are far mor powerful than standard tranq darts

Us a basilisaurus and they won’t dismount you and you can collect all the Botoxin you want while jamming Free Bird and high as a kite…

The reason I can’t craft anymore arrows…

Lost 2 maewings and a level 300 spino in the span of 5 mins to these absolutely awful creatures. Don’t go near them. If you get caught the best thing to do is whistle neutral and hope you Dino kills them. You can try to shoot them with a cross bow. Oh they also will damage shoulder mounts….. found that out the hard way…

I recommend a bow/cross bow, but if you don't have those you can hire them with a spear or pike, by luring them close to land and stabbing them.

Is there any dinos these things can't knock out??

Except for Basilo....plss tell me guyss...

Want a tip? Come in from above, slowly approach FROM THE TOP. Then spam your attack till you hear that crunch, if you get shocked off immediately pickaxe it's top👍

The best way to kill them and get bio toxin is to lure them close and kill them with arrows at close range. Then go and harvest the bio toxin with hatchet or axe.

Just out gathering stone on my doedicurus and I made the grave mistake of going into the water instantly they appear and kill me and my doedicurus.

RIP cuddles

They drop about 13-14 bio toxin

Most irritating Dino hands down kill my Giga when I was bringing it back to my base it fell off a cliff and I couldn't do anything to save it

Warning:

Do not go in if you see these.

Just kill them from shore

I— uh.. you guys bring your tames near these guys? I never travel through water on a tame other than an Icthy or Basilo. I don’t use all-terrain or semi-aquatics in the water. I don’t trust they’ll be ok. Except for my Sarco, she’s speedy as f***

The only reason I go near these things is for the night night gel

Bio-toxin is used to make shocking tranquilizer darts (once you get a fabricator) And those are super nice.

I’ve powered up the health on a couple turtles and take them into the water and they soak up damage from these while I pick them off with the crossbow.

Tip 1 dont take your dino near it unless you want to have to make a tomb stone.

Tip 2 dont go swimming with it.

Tip three jump in the water attract the evil jellies and slowly swim to shore and make these losers beach themselves and then kill them with a sword.

Iv lost dinos to them monsters. I had my bird fly behin while i was steering my raft and they killed it iv learnt my lesson.

These things are the worst bullies ever. One step and it’s killing central… we can all agree it’s a big bad bully.

Cnidaria Jellies inflict Electrocution, which paralyzes the target for a short period of time. And that's why your dino wont kill it.

Noobs, STAY AWAY FROM THEESE!!!! Please I you go near theese they will MURDER YOU!only cross rivers if you dont see any of theese than it’s safe to cross. (Unless there’s megapiranas then ur ded, oh and megs, watch out for them or ur just ded, like nothing speciel they just f***ing murder u.) so just my promise me you will NEVER go near theese.
