Description

Ghost Crab? Fiddler Crab? Ocypodidae, in any case. The guide called them Ghost Crabs (Ocypode quadrata), but the claw size looks more like the Fiddler Crab (Uca pugilator) pics I'm seeing.

As members of the family Ocypodidae, fiddler crabs are most closely related to the ghost crabs of the genus Ocypode.
