Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 16-17; Anal spines: 3; Anal soft rays: 8 - 10. Color of head and body dark reddish brown, shading to pink or reddish below. Opercle with 3 flat spines, the middle one being the largest. Vertical fins angulate in larger fish. Pelvic fins shorter than pectorals and inserted slightly behind ventral and pectoral-fin base. Bases of soft dorsal and anal fins covered with scales and thick skin. No saddle on caudal peduncle. Interspinous membranes not incised (Ref. 26938); head length 2.3-2.5 times in SL; convex interorbital; subangular preopercle, serrae at angle slightly enlarged; straight upper edge of operculum; posterior and anterior nostrils subequal (Ref. 89707).

Adults occur mainly over rocky and muddy bottoms. Uncommon around coral reefs. Usually rest on the bottom (Ref. 9710). Juveniles may be found in shallow water, but adults are usually taken from depths of 70-330 m (Ref. 13442). Feed on a wide variety of fishes and invertebrates. Are protogynous hermaphrodites (Ref. 55367). Most females transform to males between ages 7 to 14. Susceptible to red tide toxin (Ptychodiscus brevi) (Ref. 5222). Marketed fresh or frozen. The world record for hook and line, 39 lbs., from Cape Canaveral, Florida (Ref. 13442).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01413 (0.00919 - 0.02171), b=3.01 (2.89 - 3.13), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.5 ±0.5 se; Based on diet studies.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.1-0.18; tm=4-6; tmax=25; Fec=1.4 million).

Prior r = 0.4, 2 SD range = 0.24 - 0.67, log(r) = -0.92, SD log(r) = 0.26, Based on: 1 M, 15 K, 2 tgen, 2 tmax, 3 Fec records

Vulnerability (Ref. 59153): High vulnerability (64 of 100) .

Price category (Ref. 80766): Medium.
