Many of the hard clams experimentally fractured using a single point-load on the Instron failed at forces close to or above the maximum stresses that stone crabs have been shown to generate, often breaking at forces over 1000 N. Thus, repeated loading (and the resulting generation of microfractures) may be necessary to explain their success rate, especially with very large prey items. Clam is a common name for several kinds of bivalve molluscs.The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds.Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot.
