Normally found on the bottom of Ocean. These guys inflict heavy torpor so be careful if you are swimming near them as they will aggro you due to their aggressive nature. Not a lot of health but should still be cautious in groups of them especially if you're swimming alone
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.
