Tridacna

a genus of large bivalve mollusks that inhabit the coastal zone of tropical seas. There are several species, the best-known of which is the giant clam (T. gigas), which inhabits the Pacific. Its shell measures as much as 1.4 m in length and weighs as much as 250 kg. The valves of the shell are identical and very thick, without a nacreous layer. They are marked by radial plication, coarse scales, and ribs on the surface. The inhabitants of the islands of Oceania use the shells as building materials. They also use them to make household utensils, ornaments, and amulets. In addition the shells serve as money for local trade.
