Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Anal spines: 0. Black flank marking on side of tail base with short truncated posterior lobe; additional oval dark marking near base of caudal fin, but no transverse marking across midlength of caudal fin (Ref. 31367).

Probably demersal on the outer continental shelves and upper slopes (Ref. 31367). Feeds on squids (Ref. 31367). Ovoviviparous (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 13.4 - 23.6, mean 19.1 °C (based on 51 cells).

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

Bayesian length-weight: a=0.00380 (0.00194 - 0.00745), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.73 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (20 of 100).
