Dapeng Bay National Scenic Area

Uca perplexa

Physical Features：

The Uca perplexa has a similar shape and color to the Milky Fiddler Crab (Uca lactea) and is often misidentified. The major chelipeds of the former are yellow or white; the shield has mixed black and white stripes. The main feature of the male crab is that it has a triangular tooth at the end of the major chelipeds, sharp serrations on the bite edges of the two chelipeds, and brown markings on its walking legs.

Living Habits：

Uca perplexa frequently moves its chelipeds from the front to the side. It mainly inhabits mud and sandy areas at the high tide line, with granular feeding pellets often scattered outside its hole. There are also more Uca perplexa than Milky Fiddler Crabs in Dapeng Bay.
