Bright red scorpion like shrimp...

Found this critter yesterday, hiding under an old shoe, on a muck dive. Approx 30ft water in a bay that has a river mouth. Cannot find any mention in any of the ID books that I have. It was approx 1 inch / 2.5 cms, bright red, and behaving in a manner similar to a scorpion. (And it really did not want to be photographed!)

The picture is not as sharp as I would like, but it should be clear enough to get an ID.

Thank you again for your help!

Critter to be ID'd

Those don't get photographed very often. It's Microprosthema semilaeve & it's in the same family as coral banded shrimp, the Stenopodidae.

They don't get seen very often!

The folks that were diving with me got a couple of great shots too.

Thank you again Leslie!
