Maturity: Lm 31.0  range ? - ? cm
Max length : 55.0 cm TL male/unsexed; (Ref. 2295); common length : 35.0 cm TL male/unsexed; (Ref. 2295)
soft rays: 10. The inner surface of the pectoral fin axil without scales. Overall color is silvery-gray with yellowish suffusion; scale margins are narrowly brownish. Indistinct dark blotches or bars are sometimes apparent on the body. The lips are whitish to yellow. The fins are yellow, faint brown spotting may be present on soft dorsal, anal, and caudal fins. A narrow blackish bar runs across the base of the pectoral fin.
Inhabits the outer edge of the continental shelf. Feeds on bottom-living invertebrates and small fishes. Caught mainly with bottom longlines and bottom trawls (Ref. 9775).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.00659 - 0.05258), b=2.96 (2.72 - 3.20), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.7 ±0.52 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100) .
