Spondylus varius is a species of large saltwater clam, a marine bivalve mollusc in the family Spondylidae, the thorny oysters.

Description

Sphondylus varius is the largest of the spiny oysters, reaching a maximum size of about 20 cm. Aside from the size, the shell is easily recognisable because its adult part is white, but a colourful (usually crimson, but it can be yellow) prodissoconch is clearly visible at the apical end.

Ecology

It lives at a depths of 30 m, and like most bivalves, is a filter-feeder, using plankton as a food source.

Distribution

This species can be found in the Indo-Pacific Ocean and off Australia, China, the Philippines, Japan, and Taiwan.
