Biology     Glossary (e.g. epibenthic)

Minimum depth assumed from its ecology. Inhabits fringing barrier reef (Ref. 2912). Found in mangrove areas (Ref. 2908). Algae-feeding herbivore (Ref. 1456). Uses its radula to excavate a home site for grazing surface algae (Ref. 2907). Occurs at the high tide mark. Found from intertidal to 2 m, on rocks (Ref. 75835). Members of the class Polyplacophora are gonochoric. No copulation; males release sperm throught their respiratory currents and females shed the eggs into the sea. Eggs develop into lecithotrophic planktonic trochophore (Ref. 833). First reproduction occurs when individuals have reached the age of two (years) (Ref. 94892). In the Red Sea, spawning occurs during autumn (Ref. 98877).
