生物學特性     字彙 (例如 epibenthic)

A common species that occurs in sheltered sandy areas from reef flats to seaward reefs; over sandy bottoms near pieces of rubble, rock, or coral (live or dead) (Ref. 9710, 48637, 92171). Solitary or in small groups (Ref. 90102). Feeds on algae, detritus and small benthic invertebrates (Ref. 89972).
