White-handed Fiddler Crab, Uca albimana (Fiddler Crab of the Week)

The White-handed Fiddler Crab, Uca albimana, is found throughout the Red Sea, the southeastern Arabian peninsula, and along the entrance of the Persian Gulf in the United Arab Emirates. Although originally described in 1877, it was largely considered a form of another similar species, Uca annulipes, until 2010 (in fact, Uca annulipes has been split into at least four different species in the last decade).

Not a lot is known about the behavior of this species; most historical work would have been performed on one of the closely related species rather than this one (when they were all lumped together) and it is not entirely clear how much of that work can carry over to this species.
