Sally Lightfoot Crab

This colorful crustacean is known as a Sally Lightfoot crab. Grapsus grapsus is one of the most common crabs along the western coast of the Americas. It is also sometimes known as a red rock crab. These crabs are found along the Pacific coast of Mexico, Central America, South America, and on nearby islands, including the Galapagos ISlands. They live among the rocks at the shoreline, just above the limit of the sea spray. They are scavengers, feeding primarily on algae and sometimes other plant matter and dead animals.
