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.
Most annoying creature ever I was playing gen2 trying to tame a shadowmane and these things constantly interfered coming up behind me and knocking me out 1 shot. After I finally did tame a shadowmane I devoured every single one with my brand new 240 shadowmane.
