Description

Shells of Cymbiola imperialis can reach a size of 70–250 millimetres (2.8–9.8 in).[5] These large and glossy shells are elongate and fusiform, light to heavy in weight. The basic color is whitish. The spire is high, with canaliculate sutures, strong red-brown axial ribs and narrow red-brown spiral lines. The aperture is whitish, elongate-ovate, with the outer lip showing many black denticles. The operculum is dark brown, thick and small.[6]

Distribution

This species can be found in the Philippines, Sulu Sea.[2][5][7]

gollark: Also, it has incentives problems, as well as information flow problems.
