What feeding type is a fiddler crab?
Fiddler crabs eat algae, bacteria and decaying marsh plants. They feed by sifting through sand or mud for food particles. They often eat in a puddle of water to help separate food from sand. Females have an advantage over males for finding and eating food because both their claws are small.
