Length at first maturity / Size / Weight / Возраст
половая зрелость: Lm ?  range ? - ? cm Max length : 4.0 cm SHL самец/пол неопределен; (ссылка 349); common length : 3.0 cm SHL самец/пол неопределен; (ссылка 349); наибольший возраст (опубликованны данные): 4 годы (ссылка 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).
Life cycle and mating behavior
половая зрелость | размножение | нерест | Eggs | Fecundity | Larvae
Members of the order Neritopsina are mostly gonochoric and broadcast spawners. Life cycle: Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults.
