Max length : 47.0 cm TL male/unsexed; (Ref. 7251); common length : 20.0 cm TL male/unsexed; (Ref. 3696)
Carapace and caudal peduncle blackish with numerous small white spots; lips and bases of fins blackish; terminal edge of caudal fin narrowly white with a blackish submarginal band (Ref. 13442).
Found on coral reefs (Ref. 12204). Solitary or in small groups (Ref. 9710). Feeds on a wide variety of small bottom invertebrates such as mollusks, crustaceans, worms, sessile tunicates and sponges exposed by a jet of water ejected through the mouth (Ref. 9710). Marketed fresh locally (Ref. 3696). Toxins released when excited kill other fishes (Ref. 5521). Easily approached (Ref. 9710).
