Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 11; Dorsal soft rays (total): 12 - 14; Anal spines: 3; Anal soft rays: 10. This species is distinguished from its congeners by the following set of characters: 2 conspicuous vertical black bars across the head; dorsal fin with wide black margin, especially distinct in distal spinous part of dorsal fin in fish < ca. 30.36 cm SL, proximal part of dorsal fin yellow; hind margin of caudal fin with narrow black edge in fish to around 30 cm SL, disappearing with growth; 4 scale rows between fifth dorsal-fin spine and lateral line; third outer molar teeth row extending to rear end of both jaws; basal width of 6 enlarged incisor teeth at front of upper jaw larger, 1.0-1.1 mm for 16 cm SL fish, and 5.0-5.5 mm for 34 cm SL fish; D XI,12-14; A III,10; orbit diameter, noticeably larger in fish > 15 cm SL (Ref. 95256).
Adults inhabit shallow coastal waters, mainly around reefs; also enter estuaries and bays (Ref. 30573).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00870 - 0.04578), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (34 of 100).
