Biology     Glossary (e.g. epibenthic)

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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00197 - 0.01164), b=3.13 (2.92 - 3.34), 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. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (51 of 100) .
Price category (Ref. 80766):   Unknown.
