C. C. Cardiidae Tridacna


Fluted Giant Clam

Scaly Eater

Tridacna squamosa, known commonly as the fluted giant clam and scaly clam, is a species of bivalve in the family Cardiidae. It is one of a number of large clam species native to the shallow coral reefs of the South Pacific and Indian Oceans. It is distinguished by the large, leaf-like fluted edges on its shell called 'scutes' and a byssal opening that is small compared to those of other members of the subfamily Tridacnindae. 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 40 centimetres (16 in) across.
