Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 13 - 15; Anal spines: 3; Anal soft rays: 8. Distinguished by the following characteristics: tan body color with 5 oblique dark-edged pale bands; dark bands with scattered small black spots and pale blotches, especially dorsally; pale interspaces with small dark brown spots, mainly arranged in series along the middle of the interspaces; adults with dark brown line from the lower edge of the eye to the edge of the subopercle; faint dark band along the maxillary groove and continuing to the edge of the interopercle; dorsal fin and caudal fin covered with small dark spots; juveniles dark brown with black-edged pale brown bands enclosing numerous small black spots; body depth contained 2.6-3.0 times in SL; head length 2.1-2.3 times in SL; nearly flat interorbital, dorsal head profile slightly convex; 2-5 distinctly enlarged serrae on preopercle angle; upper edge of operculum almost straight; adults posterior nostril diameter 2-3 times that of anterior nostrils; maxilla reaches to or past vertical at rear edge of eye; 2 rows of teeth on midlateral part of lower jaw (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

Adults are found at depths between 80 to 383 m; juveniles in 18 to 20 m (Ref. 5222), over hard substrates (Ref. 89707). The species is apparently rare (Ref. 5222).

Estimates based on models

Preferred temperature (Ref. 123201): 16.9 - 27.8, mean 23.7 °C (based on 783 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01778 (0.01030 - 0.03070), b=3.11 (2.97 - 3.25), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.61 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec = 55,838).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (54 of 100).
