Biologia     Glossario (es. epibenthic)

Usually found over rocky areas or on coral reefs. Feeds on fishes and crustaceans (shrimps and crab) with occasional molluscs or worms (Ref. 89707). Nothing has been published on its biology. Appears to be very rare and therefore of little commercial importance. In Hong Kong live fish markets (Ref. 27253).
