When you see some you must curls them into the near of your raft.They wont attack you on the raft and you can easily shot them from it.

I dunno what all the hate is about, for a low level mobile player on a difficulty that keeps most creatures below level 40, these things really aren't bad. Sure, it'd be suicide to go in the water with them beside u, but they are the only viable source of biotoxin for me, that's gotta count for something. They're super easy to avoid once u get to know them and most times they don't even spawn near the necessary crossings at shallows, only in deep sea where most tames are entirely capable of out swimming them. Heck, I took on four cnidarias with the weakest of them being level 19 with a ramshackle pike and they barely did 200 damage to me. Just don't go at them with anything less than a basilo and they're fine. Those eels are the real worrisome ones, but cnidaria just aren't really a concern for me.

These guys bio toxin is easy to get and is very effective for keeping dinosaurs asleep

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

Megalodon lasted 10 minutes since I got it because of this, just run

I feel like you should be able to tame these guys and ride them. They could have a move that paralyzes your enemies. Up if the devs should add

Me after taming diplo: FINALLY!

Diplo:sup

Me: I’m going to cross the river let’s go.

Cnida: hmm that Diplo looks good.

Diplo gets kill

Me:NOOOO!

Ps:it took me a day (technical two half of day) to tame Diplo but, it took like 15seconds for cnida(s) to kill it plz up if this happened to you but similar R.I.P no name😔

If you have a paracer you can traverse the shallower waters and the jellies won’t seek you out. ( At least on mobile this seems to be the case.)

Me: go in ocean

Them: attak

Me: no

It A JELLY FISH! OF COURSE IT WOULD KILL YOU!

Best way to kill-get arrows stone or metal your choice

Leave all resources at base go to water 💧 shoot and run back to land then shoot 🔫 till death you can harvest bio toxin from their bodies

-Devious Trikster

When im in mobile ark i go near this creature and this creature following me near the beach but 1 or 2 cnidaria die because get push by another cnidaria and i know how to encountering it and i got my first biotoxin because that

Ez kill. All you have do is craft a bow and at least 11-15 of them depending on the group. And shove a few arrows into their heads and that’s it. Again, ez kill

Tip for beginners: dont get close to this creature. This is shock you and stop to moving for you. You can kill it with pike. Be careful.

This thing killed my crocodile RIP John

I can’t find these anywhere in Ragnorock

Run or kill them don’t take ur Dino
