Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. Dorsal fins with very small spines, very short snout, lanceolate upper teeth and bladelike lower teeth with short, oblique cusps, stocky body that does not taper abruptly from pectoral region, very large lateral trunk denticles with smooth, circular, acuspidate crowns in adults and subadults (Ref. 247). Uniformly golden brown to dark brown in color (Ref. 6871).

Found on continental slopes and abyssal plains (Ref. 6871). Feeds mainly on fish (including sharks) and cephalopods (Ref. 6871), also gastropods and cetacean meat (Ref. 5578). Ovoviviparous (Ref. 205), with 13 to 29 young per litter, born at 27-31 cm (Ref. 26346). Utilized as fishmeal, dried and salted for human consumption, or as a source of squalene (Ref. 6871).

Estimates of some properties based on models

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

Bayesian length-weight: a=0.00589 (0.00275 - 0.01263), b=3.11 (2.92 - 3.30), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 4.5 ±0.1 se; Based on diet studies.

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (Fec=13-29).

Vulnerability (Ref. 59153): Very high vulnerability (75 of 100) .

Price category (Ref. 80766): Low.
