So I thought (when I started the game) that I had lost my first tame (a dodo, I did it for the pursuit reward) but I checked tames and it was there. I requested it and it appeared. I walked across a reasonably shallow river (it was swimming pool depth) to my base. I had experienced these a million times, and when I saw 9 of these coming towards me I swam quicker and my dodo fell behind. They went to town on Pringles the Dodo.

1 up for Pringles

Lost my rock drake Tator to these guys he had 30000 hp and a good saddle and they still devoured him, but guess what I have a perfect breeding pair of rock drakes so I can always get another Tator suck it cnidaria

This stupid idiot killed my level 37 dodo

Dodo tales (Ep24 S1)

Rick was picked up by the Giga, and shaken around. Jerry looked back and noticed this, so he signaled Ares. Ares shot the Giga's.... (once again, I'm not going into detail)

It roared, and dropped Rick. He ran and made it. "Don't worry, the armor protected me" he told the others. They closed the doors and locked them. "We're safe now" Jerry stated "are you?" Said a voice. "Come on man, you again" Jerry responded. "Let us go and we won't tell anyone your dumb plans to take over the Ark" "I'm afraid it's not that easy" he told Jerry. Guards came in and surrounded them. "What a shame, I really wanted to see you get eaten, but I suppose it couldn't hurt to kill you myself."

The next thing they knew was that they were back in the Arena, but they had no armor or weapons. Then, the man came out, with shining flak armor up to his neck, and the longest pike that Jerry had ever seen. They ran, but the man threw a bola at Eden. He cried out, and fell to the ground...

180 giga: I am the strongest.

Cnidaria: *exists*

180 Giga: ima stay in the mountains.

Alright I lost a 297 lvl megalo to this bugger

Lemme explain.. so I was on a server with my friend we were having fun n stuff,

Then I thought huh I got a apprentice tuso saddle I’ll go tame one!

I set a journey off into the deep nothing happened really I never found a tuso and yes I easily did the brute cave

I was so happy I didn’t die making it across most the map until AND UNTIL I WAS SO CLOSE 50 METERS AND I CELEBRATED TO EARLY.. 5 jelly fishes killed it.. I tried everything..

So there I was, on ripjaw the baryonyx, going in to tame a megalodon near the red obelisk, despite there being at least 10 megalodons in the water.

But as I got careless, I was floating still in the water, shooting with my crossbow to tranq a megalodon, when out of nowhere, my baryonyx is shocked by these Cnidaria idiots, I forced to run back to shore, where after my baryonyx got the shock, the pack of megalodons went all in….

R.I.P. ripjaw, you served me for the longest and most memorable time.

I found a dead meg and I went to harvest it and out of nowhere a Cnidaria came and killed me with my parasaur

I feel like they should make the jellies not track and the follow you like a heat seeking missile. The dossier describes them as a passive jellyfish that floats aimlessly, and that would be TOATLLY FINE IF THEY REALLY DID THAT. These are supposed to be simple minded filter feeders, not blood thirsty killers. They don't even eat the meat why are they so aggressive, devs please nerf these dudes so they just float around in groups, I absolutely hate it when every single egg yolk knows when you enter the water, I know it's just a game, but this kind of detection is biologically impossible, jelly fish can only sense things that brush by their tentacles or move only a short distance away from them, they can't hear, or see, so tell me why these radioactive craps want anything to do with the deformed human trying to tame a dolphin. Please nerf, the ocean is so cool but its pretty much a death trap due to the jellies. They have nothing to gain. There is so much content and valuable stuff down there and yeah it's supposed to be dangerous, but we expect to be hunted by ancient sea predators, underwater titans, and the true horrors of the deep, NOT A GLOW IN THE DARK TRASH BAG. please at least lower their aggro range, yes real jellyfish are deadly, but they only kill the idiots who get too close and touch them, these things kill people because they hunt you down. I'm not saying remove them, but i just want them toned down. Thank you so much to every one who actually read my entire rant, have a great day.

Dont worry guys, ive been hunting them for bio toxin everyday and theres 3 safes full of bio toxin

These have killed two of my moschops one of my dilos and me like seven times. One up to get rid of the cndrias!

I had a wolf for 3 months it was my first ever wolf. His name was midnight. I jumped off a cliff with him at the beach. We landed in the water right on top of a pack of jellies and I died. I ran back to the beach after respawning and I watched my first wolf ever die to three jellies. Please use my mistake to protect your own tames.

Rest In Peace Midnight

So one day I was roaming with my pack of 8 dilos and then I had the brilliant idea to make my camp near a lake my dilos were on wandering mod. I suddenly saw a spino in the distance I whistled my dilos to stop. I came back with one spino and one bary. Then suddenly I saw my dinos all die to these bloody jellyfish ahhhhhhhhh

nih-DAH-ruh is how you pronounce this dinosaur.

Once upon a time.... I was near the beach side as a lowly level barely starting out near herbivore island I found a little poop dino with blue feet waddling around on the beach. It was a Lystrosaurus and he was just having a good time I decided I wanted to tame this little guy and so I did. That is how Blue Socks joined the very small family I had. I spent time with him, played with him, pet him and all was well but one thing , he couldn’t ride my raft from one side of the river to the next so I needed by boy to swim as fast as his little legs could! I whistled for him to follow and I gave him a good petting before we swam, I then swam to the other side and awaited him on the beach side. Then out of nowhere blue lights began coming it was the evil jelly’s, but it was already to late I couldn’t save him they swarmed Blue Socks and all I could do is watch as he was electrocuted to death by a dozen Jelly’s. Kill them.... kill all the jelly’s, Rip and Tear till there is nothing left....

These are mood killer, especially on Fjordur! There's too many of them spawning everywhere. Of course in groups of 20 or so. We made a base on a tiny island close to the swamps and they always spawn next to us. It's so annoying, lost so many dinos and patience already. They should nerf it.

I had a pack of 8 dilos, and one day they killed 3 other dinos without any of them dying. I was really happy and when I was walking back home I sent them after an ovirapter. The ovirapter ran into the ocean and I tried to call my dilos back but they wouldn’t come and some of these jellyfish killed all but one of my dilos. :(

Ok so at the time of this I was about level 40 ( rn I’m level 50 ) I had js tamed a sarco literally 2 minutes before and I was riding mr. Sarco ( his name ) back to my island with bloodborne ( my pt ) following. I’m an inch away from my island AND 5 OF THESE THING COME UP FROM THE BOTTOM OF THE SEA AND SHOCK ME OFF MR. SARCO AND MY PT FLIES AWAY TO MY ISLAND BY THE TIME IM FREE FROM PARALYSIS MR. SARCO IS ON 3 HP AND PARYLIZED…. Luckily I’m the god at clutches and used a grenade ;3. Rn mr. Sarco me and bloodborne are the dream team with bloodborne at level 129 and mr. Sarco at level 210 😌

I was taming a trike it went unconscious in the water but not deep enough so he would die to drowning, and then died to cnidaria

My first ever tame (a carbonemys named carbon dioxide) died to one of these. :(
