The first time I encountered them was on Ragnarok and i've seen YouTubers being really annoyed by them so I had 4 spears in my invintory so I know that they can knock you out easily so I threw the spears and it died 3-4 shots, I was surprised because of the drops. YOU CAN NOT TAME THEM

Me and my sister were on our way to go on a jungle adventure (We were playing on ragnarok and we lived at Viking Bay) and I had to stop to get water, I got a drink and my sister thought she’ll get a drink too and fill up her water skin, all of a sudden i say “Ooo a pretty tail” and then I’m knocked out. Me and my sister were playing splitscreen and we found a bug with it where when I got knocked out by the Lobster thing she did too, and she wasn’t even that close to me, so we both were screwed and we died. I then came back, killed it with my crossbow, and took a selfie with its dead corpse. Now in the present we still encounter them, but we know how to handle them. Infinite Chitin, Black Pearls, and Silica Pearls! Yay! (yes.. to this day we still live in Viking bay...)

If your a Viking Bay on ragnorok... and you see a cool looking lobster thing... DONT POKE IT WITH A STICK

Be very careful about these-they do tons of torpor damage, I was down on the bottom of the ocean (on the island) and I saw a pack of these sea scorpions. I decided to dismount off of my mosa and kill them with my pick, as that would get more black pearls. When I got close to them one of them-a level ten hit me and knocked me out in one shot. I was level 88, wearing journeyman flak and apprentice riot. And they knocked me out in one hit. The moral of the story is that these things are very dangerous.

I was just starting living on a beach I got a trike, a turtle, and a couple dilos. It glitched out and started floating above the ground and started bulling me good thing at least the trike lived.

These guy can float on land no joke............by the way

Fun fact: eurypterids count as insects for Beelzebufo's (frog) increased damage. Grab a frog, dive down into Viking Bay and get a shitload of black pearls!

Watch out because sometimes they float. Pretty sure it's a glitch but just be careful.

For you nerds out there, the specific eurypterid we see in ARK is called Megaloraprus, the second biggest species of sea scorpion right behind Jaekolopterus!!

Was on ragnarok, and was near the bay. THIS THING Sneak attacked me, and I was lucky my Dinosaur were with me and high lvls. It knocks out any pet you have on your shoulder as well. It ko my jerboa. Hope it helped! I’m still mad thou
