Clam Characteristics and Behaviour
The main lifestyle niches vary between the shallow burrowers, such as clams that live buried in the sand or mud, and the attached forms, such as mussels, jewel box clams, and thorny oysters (Spondylus).
Most of the free-living bivalve mollusks live on the ocean floor, such as scallops. They can also 'swim' by clapping their shells.
