Clams are an invertebrate animal belonging to the phylum Mollusca. More specifically, they are a bivalve mollusk, meaning they have two shells. These two shells are called valves, and their job is to protect the clam's soft inner body parts. This squamosa clam has a blue body and white valves. Parts of their body may extend beyond their valves, but they can fully retract their body and close their valves around it to protect themselves from predators whenever they need to. Different species of clams can be found in both freshwater and saltwater environments, with the larger sized species being found in the world's oceans.
