Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Anal spines: 0. Black in color, small dorsal fin spines, moderately long snout, small lanceolate teeth without cusplets in upper jaw and large high, knife-cusped cutting teeth in lower jaw, mouth moderately wide and nearly transverse, caudal fin with strong subterminal notch and short lower lobe (Ref. 247).

Demersal or pelagic near continental slopes and seamounts in depths of 550-2,000 m (Ref. 6871, 58302). Also found from the surface to 580 m over deep water (Ref. 26346). Ovoviviparous (Ref. 205). Used dried and salted for human consumption and for fishmeal (Ref. 6871). Caught rarely by longline fisheries operating in deepwater; also caught, but rarely landed, by pelagic tuna longline fisheries (Ref.58048).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Distinct pairing with embrace (Ref. 205). Presumambly viviparous, with yolk-sac dependancy (Ref.58048).

Estimates based on models

Preferred temperature (Ref. 115969): 4.1 - 12.6, mean 7.7 (based on 948 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00168 - 0.00901), b=3.13 (2.94 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.60 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): Moderate to high vulnerability (54 of 100).

Price category (Ref. 80766): Unknown.
