Ohhhhh man these things are annoying and great as they are pretty much the only thing that gives bio toxin and they are also pretty much the only thing that stuns my Dino’s and kills them also 1 like = 1 R.I.P for my mosasoar

This things killed all I ever had if there in ark 2 screw this world

I WISH THESE SHUTS BURN IN THE HOTTEST FIRES OF HELL.

I was in my hardcore world doing some traveling, and I hat to cut across the water to bring my dinos. I grabbed my water ones first, my level 124 Sarco "Shank", my Itchy, and my two 200+ level Moscops Mr. and Mrs. Snazzy. Water was cleared of megalodons and such, so I swam with my tames following me. I safely get across but notice my tames aren't there. I see them still near the beginning of the other side, staying still. I swim back over just to watch Shank die to a megalodon. I notice all my other tames are gone. I was so confused, it was a relatively low level Meh so my tames should have destroyed it. I killed the Meg in rage, and noticed the jellyfish, peeking from around a rock. They stunned my tames and made the Meg be able to kill them. Words cannot explain my anger and sadness. I straight up deleted the entire world, hardcore and lots and lots of work out into, and haven't played the game for a month or two. I miss you Shank :(

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

I was compy hunting, and i died to these guys. They are a pain, but on land, they are nothing except free bio-toxin. I lured them onto the beach, killing them. Suckers.

Owner of Peepee the Sarco, I almost cried reading that story. May Peepee the Sarco rest in piece

I had 2 dilos that ONE of gelatins killledddd

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

One day I was hunting them for bio toxin and I forgot that my kapro was on follow and she get in the water and tried to kill it but she died now I killed every cnidaria on my sight

My pack of 12 dilos chases an oviraptor into the ocean I only saw the sparks of my dilos getting stung. I called my dilos back multiple times and only 6 came back. I got stung a couple times but I killed the 3 Cnidaria and got revenge.

These things are so annoying and I do not know why they have a name section because I am pretty sure that you cannot tame them.

I've lost something like ten Mega-Sharks, four Barron's to these. Little story, so a few days prior to my story, a ton of my Baryonyxs escaped. I couldn't catch them, so I let them hunt. Earlier today, one got attacked by a single Jellyfish, and died... I hopped onto my Mosa, and immediately killed it it.

this piece of crap killed my lvl 246 giga and lvl 79 raptor. i hate these things so damn much, and i will kill every living one i see until there is no light on my world. i am entering my villain arc.

Don’t go near that bro I got my rock drake kill with 12k health kill in like 1 minute or 4 minutes it’s not good man

So, the harsh trip with a happy ending is as follows.

I have several bases on mobile single player, and I'm thinking of making one near the snow just b4 it starts getting cold(I messed up my é grams and now I can't go there cuz I have no fur clothing).

I got on my queen spino lvl 41 and went in snow, we were there b4, so I was confident.

We were checking the area when suddenly I get the red screen as a warning about the cold. I quickly ran off to the warmer shore, to make it even a smaller distance, I made my spino swim between the snow on the water, (smartest choice ever.....)

At the last iceberg, I fell into 3 cnidania, yes those beauty killers, I tried everything to save my spino, and from idk where, a megalodon killed me and I respawned back on base, quickly getting in to tame menu, spino is still alive!!!

(since I was knocked off and spino was on passive, I belive mega didn't wanna die so he didn't attack spino). So I went like REQUEST! REQUEST! REQUEST!

Spino is home, 200/1557hp

This guy killed my high level bary that could kill spinous Rex’s allos broncos etc but not this f££££king guy

One time I was taming a pt and some bio toxin because it’s torpor was dropping luckly I had my high level Baryonx named light and sended lighty to attack the jellyfish but suddenly guess what to lighty he died I wish these weren’t even added

One like one respect for lighty

Back when I was playing on easy I brought my op lvl 45 sarco into the water. 5 mins later... I brought my sarco back to the Meg I was taming (I play with my dad) I got off and turned around saw the monsters coming at me and I thought my sarco would destroy them. I was wrong. Me and my dad and the remaining baryonyx had to rush to shore before we died. Tips:

Baryonyx swipe attack only works in the water so just swipe these idiots and kill/run

Crossbow + stone arrow works in the water so while swimming backwards shoot em to bits.

The weird long sea cow (sos I don't remember it's name) is immune to these monsters!! rip for all the tames that died to this animal. Now I just kill those things on sight

Lost a spino . a baryonyx , and a thrizino by these dudes

My Parasaur got electrified out of existence because of this thing. Me and my Parasaur were swimming AND THE THIS LITTLE BRAT (Cnidaria) CAME OUT OF NO WHERE WITH ITS FAMILY AND THEN ELECTROCUTED OUT OF THE FRIKIN EXISTENCE
