Short description Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 43-45; Anal spines: 1; Anal soft rays: 39 - 42. Identified by the long filaments on the dorsal fin of the male (Ref. 48636). Body scaleless above and below lateral line on anterior half (Ref 12934).

Biology     Glossary (e.g. epibenthic)

Found in coastal reef slopes and deep outer reef lagoons in current channels. Usually in large groups with several large males (Ref. 48636). Inhabits sand-rubble bottoms (Ref. 90102). Found hovering above sandy slopes. Usually forms a harem of one male-phase fish and about a dozen female-phase fish (Ref. 37240). Normally buried when no current is running (Ref. 48636).
