“Boring Clam” (Tridanca corcea)

Also known as the Crocus Clam, Corcea Clam or Saffron-coloured Clam, Tidanca corcea is a species of Tridacnid clam that is widely distributed throughout the west Pacific. Like most bivalves boring clams are filter feeders and will siphon nutrients from the water around them. Despite what its common name might suggest Tridanca corcea is actually quite interesting and will bore itself into hard substrates to keep itself affixed.

Fluted Giant Clam (Tridacna squamosa)

Also sometimes known as the scaly clam, the fluted giant clam is a species of “giant clam” (Tridacnidae) which occurs in shallow coral reefs throughout the South Pacific and Indian Oceans. T. squamosa can be distinguished from other members of the genus by its large “leaf-like” edges on its shell known as ‘scutes’. It is also noted for having a relatively small byssal opening when compared to other Tridacnids. Despite their size like other bivalve species fluted giant clams are sessile filter feeders.
