Collection of crab photographs. Crabs are crustaceans, living in all oceans, on land, and in freshwater. They are short-tailed, but mostly their tail is hidden. The creatures mostly live in the sea. Living on land these animals sometimes visit the sea to pass their early stages in it. They are breathing through gills, but the land crustacean, the cavities are large and act as a lung. Because they have 10 feet, we call them Decapod. Usually, they step sideways but are also able to walk forward and backward. Check it out next time when you are on the beach. They communicate with each other by drumming and waving with the pincers. You can purchase a photographic print in our collection of crab photographs.
