Clams

Clams are animals that burrow under the sea floor. They are bivalves, mollusks that have two shells to protect a soft body. There are over 15,000 different species, worldwide. The biggest clam is the Giant Clam, that is up to 4.8 feet and weighs 550 pounds. Most clams are only a few inches long. They are many colors like brown, red-brown, yellow, and cream. When a clam is threatened, the clams will pull their body into the shells and close them for protection. Clams have a foot to burrow into the sand and tube-like siphons to draw in water. They extract oxygen from this and also filter plankton to eat.
