They suck they will kill you Dino ulmost instantly and u bc they shock you and you go very slow only good thing about them is there bio toxic there’s like no way to escape from them if you’ve been shocked.

Use a cross bow or stand on the beach and shoot them with a ascendant longneck rifle

Just don't get to close and kill them with a crossbow

Pikes and Crossbow works best. I always love going underwater and make bases there. With tek gear Ofcourse. They are easy. Pikes i used mostly becuz they have more reach than the swords.

If you spawn craft a range and kill it that’s it. If it dies then you won’t have to be scared about it shocking you

Basilos are immune to the shocks! You can now avenge all your dead tames.

Shoot it with a long range weapon on land

Fun tip: basilosaurus are not affected by the stun so get a basilosaurus are rain hell down on these evil jellyfish!

I have figured out a way to kill them so easy all you have to do is get them near this the land get it just keep on dipping yourself and water and then eventually they’ll beat them selves and then you can harvest them for their biotoxin

How to kill that on one hit without weapon

Step 1 lie in water And bug game

Step two wath how that crap go to surface And die

You will underestimate This guy, he will do nothing but can still take out an entire army of gigas. DONT MAKE THE SAME MISTAKE I DID

Did anyone thinks 🤔 like me that what if they are tamable 😈 and once TAMED they give you bio toxin somehow🤔🧐

Beautiful from afar,

We shimmer like shining stars.

But come near me,

And you'll quickly see,

You're mistakes leaves everyone scarred.

They can put you to sleep by electrocution, so be careful! I've lost a sarco and a meg to theese shiny seductors. On an unrelated note, jumping on their tops isn't an option. Nemo lied to us. ~CL1

Hide your kids hide yo wife and hide your husbands while your at it cuz we got jelly fish killing everybody

These are really ez to kill. Just go to the shore, get out your crossbow, and should em. I once fought six of these guys and killed em all. I hope this helps yall

Me thinks “ok it cannot see me it has no eyes, if it attacks me I will kill it. Five seconds later, I CANNOT MOVE“ I lost my pets that day also the same day my base got raided by a large creature I don’t know which one but RIP game

There aren’t very many ways to kill them. One method is to use a titanosaur or possibly a bronto to kill them, use an argentavis to kill any floating above the water, or a crossbow. It may be possible to use a diplo to push them if they are too close to your aquatic pets.

In mobile, if you ever got your precious dino get stinged by these, you can either equip your strongest melee weapon and kill the cnidaria or quickly jump back on land and go to your inventory -> your charater info -> look into the stat section then find and press the tame button (it will bring up the list of all your tamed)then select the name of your endangered dino and chose request, it will take a short amount of time(about 20 seconds) for the request to be done then after it done, your dino will be next to you

NOTE: for land dino, you must be on land in order to request, for sea dino you can either request while in water or do it on land then jump back in

I had save my megalodon from cindaria 2 time and my rex 1 time now

Up if found useful

Kill quickly without any danger or ammo:

This just happened to me accidentally, but it seems useful. Get just close enough to make them follow you. Rush back to the beach. Wait for them to get close and then move down the beach away from them. Try to get them as close to the shore as possible. If they get too close to you, just get on the beach and add a little distance. When they are close to the shore, move around them on the beach and go back in the water (on their opposite side). They will all go on the shore and die. Collect your biotoxin

How to kill:

Find some in the shallows

Lure towards shore or at least to where you can stand Shoot with bow

Boom! Bio toxin
