A type of porcelain crab, probably flat top porcelain crab

Not the flattop porcelain crab(petrolisthes eriomerus), but the flat porcelain crab(petrolisthes cinctipes). Flat porcelain crabs have red mouth parts, flattops have blue mouthparts. Also red antenna go for Flats. Super confusing common names, but I’m a crab biologist and very certain of my ID!

Flat porcelain crab most beautiful blue I've seen on a crab. Any other really blue crabs that you know of ? I thought it was a rarity

Oh my gosh thank you! I found a dead one washed on the beach earlier this year and I hadn't seen a crab that blue in the tide pools before. Some crawdads will get real blue like this but I hadn't seen anything quite like this before.

I agree, flattop porcelain crab.
