Further characterized by body depth at gill opening 18-23 in TL; origin of dorsal fin slightly closer to gill opening than corner of mouth; anus anterior to middle of body; front of upper jaw with three rows of teeth with 3-4 canines on outer row on each side, small teeth in between; two large canines of middle row; side of upper jaw with outer row of small teeth; about four large teeth in inner row; row of small teeth on each side of lower jaw; front of jaw with two pairs of small canines (Ref. 90102).
Body shape (shape guide): eel-like; Cross section: compressed.
Occurs at reef flats and outer reef slopes to a depth of at least 20 m. Feeds on fishes, cephalopodes and crustaceans (Ref. 89972). Unlikely to be encountered without the use of ichthyocide (Ref. 1602, 37816, 58302). Benthic (Ref. 58302). Possibly a protogynous hermaphrodite (Ref. 32169). Common, but highly cryptic and seldom seen (Ref 90102). Minimum depth reported taken from Ref. 86942.
