Description

Clam is a common name for the different kinds of bivalve mollusks. This word is applied mostly to edible and infauna species who spend most of their lives buried in sand on the seafloor or riverbeds. Clams have two shells which are of equal size and are bridged by two adductor muscles. Their burrowing feet are very powerful. They live in both marine and freshwater environments. In places with abundant salt water, like North America, they burrow into the mud and the water turbidity that is required varies with the location and the species. They are found across the world along sea coasts and river shores.
