Length at first maturity / Μέγεθος / Weight / Age
Γεννητική Ωρίμανση: Lm ?  range ? - ? cm Max length : 4.0 cm SHL αρσενικό/απροσδιόριστο; (Αναφ. 349); common length : 3.0 cm SHL αρσενικό/απροσδιόριστο; (Αναφ. 349); μεγ. αναφερόμενη ηλικία: 4 έτη (Αναφ. 8702)
This species can be distinguished by the following characters: shell thick, subglobose with flat spire; outer surface polished and smooth; columella smoth; presence of small denticles at inner margin of outer lip aperture. Colouration: shell variable white, cream, brown, dark grey or green, marbled, streaked or spotted; aperture and columellar shield glossy white (Ref. 128042).
This very common species is prized for food and for its attractive shell (Ref. 349). Depth range based on species' occurrence data in Taiwan (Ref. 109505); to be replaced with a better reference. Common in intertidal shores of Capiz (Ref. 128042). Usually buried in sand during the day and emerging at night to graze on nearby rocks (Refs. 349, 799). Exclusively herbivorous and feeds on algae (Ref. 122680). Also found in mangrove areas. Part of both epibenthic and arboreal communities (Ref. 128397).
