Biology     Glossary (e.g. epibenthic)

Occur in shallow outer reefs subject to surge (Ref. 9770, 48637). Commonly found over barren rock or the spur-and-groove zone where there is a mixture of bare rock, rubble, and coral. Juveniles on algae reef (Ref. 48637). Benthopelagic (Ref. 58302). Feed on algae, detritus, mollusks, crustaceans, worms, echinoderms, fishes, sponges, foraminiferans, and eggs. Territorial. Oviparous (Ref. 205). Also taken by drive-in nets (Ref. 9770). Minimum depth reported taken from Ref. 128797.
