Biology     Glossary (e.g. epibenthic)

Occur in seaward reefs to depths greater than 60 m (Ref. 9710 , 48637 ), with rich invertebrate growth (Ref. 48637 ). Common in coral-rich areas exposed to currents (Ref. 1602 ). Usually at moderate depths in small loose groups (Ref. 48637 ). Benthopelagic (Ref. 58302 ). Diet consists mainly of algae and detritus but also takes in crustaceans, octopuses, sponges, and fishes (Ref. 1602 ). Oviparous (Ref. 205 ). Also taken with drive-in nets. Marketed fresh (Ref. 9770 ). Minimum depth reported taken from Ref. 128797.
