Descrição breve Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 2; Espinhos anais: 0. Dark brown or blackish in color, dorsal fins with fairly prominent fin spines, moderately long snout, lanceolate upper teeth and bladelike lower teeth with short, oblique cusps, stocky body that tapers abruptly from pectoral region, and moderately large tricuspidate and tricarinate lateral trunk denticles (Ref. 247).
A rare species inhabiting lower continental slopes (Ref. 26346), also on insular slopes in large schools near the bottom which are segregated according to size and sex, and feeds on cephalopods and bony fishes (Ref. 247). Up to 36 young in a litter, ths size at birth between 32 and 36 cm (Ref. 247). Used for fishmeal and liver oil (Ref. 6871). Minimum depth from Ref. 247. Ovoviviparous (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00220 - 0.00627), b=3.12 (2.98 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Nível Trófico (Ref. 69278): 4.5 ±0.59 se; based on food items.
Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
