Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 13-14; Anal spines: 3; Anal soft rays: 8. This species is distinguished by the following characters: body oblong, its depth less than head length and 2.8-3.3 in SL; preopercle rounded, finely serrate, the lower edge fleshy; opercle with 3 flat spines; upper edge of operculum almost straight; 1-3 large canines at midside of lower jaw; gill rakers of first gill arch 7-10 + 15-18 (including 6-87 rudiments on each limb); D IX,13-14; caudal fin lunate, the upper and lower lobes produced, about twice length of middle rays; pectoral-fin rays 16-19; lateral-line scales 66-77; lateral scale series 113-135. Colour of head, body, and median fins yellowish brown to orange-red (specimens from deep water more reddish) with numerous small round or elongate spots of blue, lavender or pink; rear margin of median fins broadly yellow; pectoral-fin rays red to brown, the distal third abruptly yellow[ large juveniles (10-25 cm SL) with irregular black band along dorsal part of body ending below rear of dorsal fin and continuing on head (up to eye) as 3 irregular black spots; black blotch at base of upper caudal-fin rays; head and body (including black band) with small pale blue to pink spots; a pale yellow or white stripe mid-dorsally on head from tip of lower jaw to dorsal-fin origin; small juveniles (< 7 cm SL) lack the black band and black spots on dorsal part of head and body (Ref. 39231, 89707, 90102).

Biology     Glossary (e.g. epibenthic)

Usually seen in clear-water areas at depths below 15 m, and prefers islands and offshore reefs rather than continental shores. Feeds mainly on fishes, and on crabs, shrimps and stomatopods. It is highly appreciated for the quality of its flesh. It may not be sold in Mauritius because of cases of ciguatera poisoning (Ref. 11888). In the Hong Kong live fish markets (Ref. 27253). This common and important food fish is caught with handlines, spear, and traps (Ref. 39231).
