Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 15 - 17; Anal spines: 3; Anal soft rays: 11 - 13. Distinguished by the following characteristics: Side body has rectangular dark gray blotches. Outer third of second dorsal, anal and caudal fins black. Edge of preopercle smooth, without pronounced lobe at angle; 17-24 total gill rakers (Ref. 26938); depth of body 3.3-3.5 times in SL; head length 2.5-2.8 times in SL; evenly rounded preopercle, without distinct notch or lobe at the angle; subequal sizes of anterior and posterior nostrils (Ref. 89707).

Minimum depth from Ref. 126840. A solitary species (Ref. 26340) inhabiting rocky and coral reefs (Ref. 9710). Adults feed primarily on fishes; juveniles mainly on crustaceans. Oviparous (Ref. 205). A protogynous hermaphrodite (Ref. 55367). Forms spawning aggregations (Ref. 55367). Common but difficult to approach (Ref. 9710). Marketed fresh and its flesh is of excellent quality.

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

A monandric species (Ref. 55367). According to a study in Campeche Bank, females changed sex between 85.5 and 125.0 cm FL, with median length of 103.3 cm FL. At 114.5 cm FL, 50% of the females in the sample had transformed into males. Age at sex change = 15.5 years (Ref. 55367).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00850 - 0.01290), b=3.05 (3.02 - 3.08), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.5 se; based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.16; tmax=14; Fec=500,000).

Prior r = 0.49, 95% CL = 0.33 - 0.74, Based on 1 data-limited stock assessment.

Fishing Vulnerability (Ref. 59153): High vulnerability (63 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (88 of 100).

Price category (Ref. 80766): Very high.
