The fluted giant clam, Tridacna squamosa, is one of a number of large clam species native to the shallow coralreefs of the South Pacific and Indian oceans. It is distinguished by the presence of large leaf-like fluted edges on its shell called 'scutes' and a byssal opening that is rather small as compared to other members of the Tridacnidae family. Normal coloration of the mantle ranges from browns and purples to greens and yellows arranged in elongated linear or spot-like patterns. Tridacna Squamosa grows to 16 inches across.
