Description

The shell of this species is variable in degree of sculpture, depending on how exposed or sheltered the environment is in which the snail lives. These different forms are called ecomorphs. The shells can reach 73 mm in size.[2]

Distribution

This species is found in shallow intertidal waters, usually on rocky shorelines and in reef flats. It is native to the Central Indo-Pacific, from Northern Australia and New Caledonia to Japan, Southeast Asia, and the Andaman Sea.[3]
