Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 5; Dorsal soft rays (total): 21; Anal spines: 1; Anal soft rays: 16 - 17. This species is distinguished by the following characters: D V,21; A I,16-17; pectoral-fin rays 14-16; lateral-line scales 46-48; 4 progressively larger, recurved canine teeth on each side at front of lower jaw; ctenoid scales on body except prepelvic area with cycloid scales; opercle and cheek are covered with ctenoid scales; body depth 4.7-5.5 in SL; caudal fin is truncate to slightly rounded; pelvic fins reaching beyond the anal-fin origin; colour of head and body generally white with 7-8 short brown bars on back, above lateral line and lower side with corresponding narrow yellow-orange to brown bars; adult has conspicuous black band on rear edge of cheek and short black band on lower pectoral-fin rays; females have a curved black band under eye along lower edge of suborbital (Ref. 116121).
This species lives in a relatively unusual habitat, consisting of a nearly enclosed, narrow, dead-end lagoon, with a gradually sloping, white sand bottom with scattered, mainly low-profile, coral formations, occurring as solitary individuals (Ref. 116121).

Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
