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

People who thinks these are strong just kill them with a pike or crossbow and if your not that lvl use a bow and if you are not the lvl accept your fate you noob

The animal like a long whale can anti this damage

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

Best way to deal with these things. Shotgun and raft combo. You sail the raft close to them, stand on edge of raft, and shoot them point blank. These jellyfish are worse than the Box jellyfish and or man o’ war jellyfish we have ILR, and need to be exterminated.

Side note. The raft and shotgun combo works for exterminating other hazardous sea life as well. Like so that new players will know how to deal with these things efficiently.

Another side note. Rafts are perhaps the best thing to have if you plan on taming any sea creatures. Put a generator and an auto turret on a raft to make a mobile safe zone for your aquatic tames. It really helps.

Another side note. Auto turrets are mid to late game, generators are mid game. Be wise with your engrams, and be sure to follow the below strategy.

From level 1-75 unlock all the weapons and saddles, then produce two of each saddle. After which, you’ll want to use mind wipe to reset your engrams and unlock all the armor. Produce two sets of each armor. Mind wipe a second time, then use your engrams to unlock whatever else it is you may need. That mind wipe is perhaps the most useful recipe in the game. Best way to get the recipes is to go to a cave and farm the creatures in there for recipes and ammo. Always be sure to check the inventory of everything you kill, you might find some useful gear.

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
