Fiddler Crab

Fiddler Crab
The fiddler crab, characterized by the enlargement of one of the claws in males, is commonly found on beaches and in marshes throughout the temperate and tropical regions of the world. Although greatly enlarged, the male’s claw is not used for combat but rather for attracting females during mating season. As at home on exposed beaches as it is under water, the fiddler crab prefers the shelter of a shallow burrow when covered by the tide. Fiddler crabs feed on plant debris, decomposed organic matter, and even carrion.
