Short description Morphology | Morphometrics

Anal spines: 0; Anal soft rays: 0. Dark grey-brown in color, dorsal fins with very small fin spines, very short snout, lanceolate upper teeth and bladelike lower teeth with short, oblique cusps, stocky body that tapers abruptly from pectoral region, moderately large dermal denticles with triple cusps and ridges in adults and subadults (Ref. 247).

Found on continental and insular slopes (Ref. 247). Occurs in large schools near the bottom which are segregated according to size and sex (Ref. 247). Feeds on cephalopods and bony fishes (Ref. 247). Ovoviviparous (Ref. 205), with up to 36 young in a litter. Size at birth between 32 and 36 cm (Ref. 247). Used for fishmeal and liver oil (Ref. 6871). Minimum depth from Ref. 247.

Estimates based on models

Preferred temperature (Ref. 115969): 5.1 - 8.8, mean 6.9 °C (based on 105 cells).

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00490 (0.00201 - 0.01192), b=3.13 (2.92 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.59 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec=36).

Vulnerability (Ref. 59153): High to very high vulnerability (73 of 100) .

Price category (Ref. 80766): Unknown.
