Give FeedbackFiddler Crab (Uca)
The fiddler crab gets its name because of the size of the claws on the male. One of its claws is much larger than the other. When he waves them through the air it appears as if he is holding a bow and playing the fiddle. The mud fiddler is black or deep olive. The red jointed fiddler is brown or dark gray with red patches at the joints of the large claw. These two types of crabs usually make their homes in mudbanks. The sand fiddler is violet gray or olive. Its claws are lighter in color. It loves a sandier environment as his home.
