Short description Morphology
Shell large, heavy, conical, with rounded shoulders. Umbilicus deep and round, operculum multispiral, circular. Colour: purple-black on a whitish background; aperture white, internally nacreous; operculum iridescent brown.
Stocks have been locally extirpated or are diminishing due to over exploitation (Ref. 355). Shallow subtidal, on rocks and shell rubble (Ref. 355). They are also found in intertidal and offshore coral reefs, particularly on algae, boulder, and coral habitats (Ref. 83934). Herbivore-detritivore. Most feeding seems to occur at night and early morning. Feeds on a wide variety of algae, sand and detritus (Ref. 105349).
Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Broadcast spawners. Spawning occurs during lunar period. Females lay eggs in ribbons or jelly masses in the substratum, after the males have released their sperm (Ref. 105346). Males don't have penis (Ref. 105349). Life cycle: Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults (Ref. 833).
