Just jump into the water near shore then wait for them to get really close then quickly get back on shore and they will be near the shore, then use a spear or range to take them out, but keep a distance because they still can attack you, and there you go, easy bio toxin for day

As long as you on the shore and NOT underwater, they wont come for you

This Jellyfish just killed my level 15 Dilo I swear I'll have revenge

Try using far range weapons. These guys will drop BioToxin.

All you need to do is swim above it and far enough away we’re you can’t get stung. Then just pull out your sword and swing while swimming backwards. They hardly have any health and you will take them out in a few swings with a pretty solid sword. Just make sure you don’t get close or you will die!

Here’s a massive tip that I’ve learned that I find helpful and you might or might not. I’ve found out that setting my tames on creatures like paras next to the sea is the worst idea, they will run into the sea and your tames will follow. I have lost tons of raptors, paras, Ankys and even Rex’s to these stupid jelly fish and there’s nothing I can do but watch. I play on mobile evolved so my experience might be different to yours.

These Guy are awful, I had four Raptors and they killed all of them as I was going through a river.

Here's a tip in killing a cnidaria without having to kill it with any weapons or dinos:

•Get in the water close to them(not so close unless you want to die)

•let them follow you

•get out of the water

•They'll be now almost out of the water

•Get back in side and let them turn

•They die because of their turning issues

That's use full to get them Biotoxin (Note that I don't know if this works on any other devices,only I know it works on mobile)

They're good to get some useful Biotoxin!

FOR THOSE WHO HAVEN'T CONFRONT THEM YET OR HAVEN'T SEEN THEM: DO NOT GET CLOSE THEY GO IN PACKS OF 5 OR 6 I TRIED TO GET CLOSE TO SEE THEIR NAMES AND ALMOST DIED, I HAD TO KILL 2 OF THEM TO GET BACK AT LAND QUICKLY TO LIVE.

Killed my spino a week ago And now I have more biotoxin than I know what to do with. TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT

Rest in electrocuted pieces Barry you will be missed. Them darn jellyfishes ended my aquatic adventures and lvl180 baryonyx real quick!

Kill 999999999999999999999999999999999999999999999999999999999999999999999999999999999999 of these

if you see this pest under water, try to move it to swallow water and you kill it as they stand still. if you see it on open sea, go to your raft and move the cnidaria close to your raft and you kill it. but if you already on deeper water, go near a wild water creature and us it as cover. but if there is no wild creatures, try find high rock or try slip your body on rock and you kill the cnidarians, but if there nothing and just you and cnidarians. well nothing to do unless u bring your megalodon or other water creatures that you tame 😁

They have pretty long range. So if you see them just dont dive into water, first kill them from range weapon. And if you are already inside water then see if they are moving to check they spotted you or not. If they are not moving then simply change your way and dont try to fight, if they are moving then you better run in opposite direction for your life.

Atleast electrophorus can be tamed...

Just to let you guys know, Basilo is not the only tame which doesn't dismounts you in case you get shocked.

Direwolf doesn't need a saddle... meaning they don't dismounts you on impact, that's why using a high lvl (cave ..if u will) direwolf u can farm Bio-Toxin easily... without the need to have another tame.

I don’t get why people want to tame this, like seriously, it has no mouth (or brain for that matter) so why to people want to tame this, come on what will it even eat?

This thing will stun you nock you out and murder the crap out of you

These things suck! They Killed my lvl 257 Rex. But I avenged his death! Build a boat and get a crossbow and they are easy to kill. R.I.P Giant.
