Biology     Glossary (e.g. epibenthic)

Occurs in small groups over seagrass beds, sand and rubble areas of coral reefs, deep channels, and lagoons. Usually found in shallow water. Usually seen solitary but sometimes swims in small groups. Juveniles in seagrass beds (Ref. 48635). Feeds mainly on crustaceans, fishes, and echinoderms.
