Where seen?
This narrow conch with black lips is sometimes seen in seagrass areas on our shores. Elsewhere, they are found on sand or sandy mud bottoms, sometimes associated with sparse algae. Often occurring in colonies. Intertidal and sublittoral zones to a depth of about 40 m.

Features:
3-5cm long. Shell thick, long and narrow without a very broad flared portion. The shell opening is black, although in some, this may appear as just a black border around the edges of the shell's underside. The animal is greenish sometimes with white or with beige spots. Like other conch snails, it uses its pointed operculum to hop along.

Human uses:
The snails are actively collected in the Philippines and often sold in the markets of northern Luzon. Shell frequently used to make decorative items.
