Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. Bladelike unicuspidate teeth in lower jaw and teeth with cusps and cusplets in upper jaw, relatively short snout, low, truncated denticles (Ref. 247). Blackish brown dorsally, with an obscure broad black mark running above, in front and behind pelvic fins (Ref. 247).

Found on or near the bottom of continental and insular slopes at depths from 275 to 1,000 m (possibly to 2,000 m); also oceanic in the south Atlantic from the surface to 710 m (Ref. 6871), possibly as deep as 1998 m (Ref. 58302). Feeds on fish eggs, lanternfish, squid, and other small dogfish (Ref. 5578). Ovoviviparous (Ref. 205). Utilized dried salted for human consumption and for fishmeal (Ref. 247).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00339 (0.00203 - 0.00564), b=3.06 (2.91 - 3.21), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 4.2 ±0.4 se; Based on diet studies.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Vulnerability (Ref. 59153): Moderate vulnerability (43 of 100) .

Price category (Ref. 80766): Unknown.
