Clam. Clam is a common name for several kinds of bivalve mollusc. 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 sea floor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. [1]
Some pea clams (genus Pisidium) have an adult size of only 3 mm (0.12 in). In contrast, one of the largest species of freshwater bivalves is the swan mussel from the family Unionidae ; it can grow to a length of 20 cm (7.9 in), and usually lives in lakes or slow-flowing rivers.
Characteristics. This large clam shrimp presents a body colouration varying from orange to rose, and a dark maroon shell; the eggs carried by the female are yellow to orange. [1] The species is distinguished from other Lynceidae members because the males have a pair of large claspers, with the right clasper being larger than the left.
