Gyrineum perca explained

Gyrineum perca is a species of predatory sea snail, a marine gastropod mollusk in the family Cymatiidae. It is more commonly known as the winged triton or the maple leaf triton.^[1]

Description

Shells of Gyrineum perca can reach a length of 31-. 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.^{[2] [3]}

Distribution

This species is widespread from the Eastern Africa to Japan.^{[4] [5] [6]}
