Quick Summary
The marsh fiddler crab, Uca pugnax, is a species of fiddler crab found along the Atlantic coast of the United States. Fiddler crabs are named for the male's disproportionately large claw, which it holds like a violin. While the female has two small claws, the male's large claw can regenerate if lost. These crabs live in burrows on beaches in temperate to tropical regions and feed on algae and other organic matter. Males are typically more colorful than females, with colors ranging from red and green to yellow and blue.1
