Iridescent Scallop
Pedum spondyloideum
Pedum is a monotypic genus of bivalves belonging to the family Pectinidae, the scallops. The only species is Pedum spondyloideum and it is the only genus in the tribe Pedini. Sometimes referred to as the iridescent scallop, this species is found throughout the Indo-Pacific.
Among scallops, this species exhibits a unique lifestyle where they "bore" into live coral, creating a narrow "burrow" or niche that these scallops inhabit throughout their life.

Description
The two shell valves of Pedum are fan-shaped and asymmetrical: the right valve has a deep byssal notch, is inflected, smoother, and is wider and larger than the left valve, which is flattened, possesses radial lines and spines. The scallop's mantle folds and tentacles are part of its visible anatomy; two tentacle types have been observed: a wholly white tentacle and a brown-striped variety. Like other scallops, Pedum possesses eyes.
