I was farming oil in Viking bay. No joke I turn around and 20 of them are coming at me I get on my beaver and run ran out of stamina and got hit instantly became unconscious and died watch out for them but you can get lots of black petals from them.
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.
