Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 12 - 13; Anal soft rays: 10 - 12; Vertebrae: 49 - 50. This species can be distinguished by the following set of characters: D 12-13; P 14-15; lateral-line scales 53-55; rows of transverse scales 4 1/2 above lateral line, 5 1/2 below lateral line; pectoral fins moderately long (reaching at or just above the line form origin of pelvic fins to origin of dorsal fin); 2 rows of teeth on outer palatines; 0-3 teeth on vomer; tongue with ca. 4-5 rows of teeth posteriorly; caudal peduncle compressed (depth greater than width); stomach and intestine pale whitish (Ref. 101339).

Found at depths of 57 to 127 meters. The largest specimen was 40.10 cm in standard length (Ref. 101339).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00501 (0.00236 - 0.01065), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.4 ±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): Moderate vulnerability (39 of 100).
