These guys can swim on land for some reason and chase you like a hover-scorpion.

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

Sending this tip as I’m currently knocked out by this broken lobster, run when u see it.

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.

Is it just me or can theses things levatate

These guys are very rare to find in mobile but they DO exist.

As if troodons weren't enough u got these bastards

As I'm writing this I am slowly dying by a level 3 eurypterid that keeps on spawn killing me

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!!

Are these in Ark mobile?anyone please answer
