Description

Shells of Biplex perca can reach a length of 31–100 millimetres (1.2–3.9 in).[4] These unusual shells are quite flattened, well adapted to laying on a soft substrate, with large flanges close to the outer lips and a blade-like outpouching of the outer shell layer, forming two longitudinal folds (hence the genus name). Shell surface may be whitish, yellowish or pale brown.[5][6]

Distribution

This species is widespread from the Eastern Africa to Japan.[4][7][8]
