Brazilian Fiddler Crab

Uca maracoani

• Group: Crab

Males of this Brazilian fiddler crab carry one hugely enlarged claw, waved like a flag to court females and warn off rivals across the mudflat. Each digs a simple burrow about 40 centimetres deep, sometimes shared, and feeds by sifting organic scraps from the mud.
