I was thinking Emerald Mithrax crab too, but never seen one with a crusher claw like that!

Ya I missed seeing the big claw, interesting. The other claw looks exactly like an emerald crab claw.

Yeah, kinda weird. Could just be an Emerald with a messed up paw! Looks speckled on the head too, that's a strange one there...
I know....it's an Emerald Pistol Crab!! Just kidding.
Good luck with the ID.
