(See ETYFish);  atromarginatus: atro-, from ater (L.), black; marginatus (L)., bordered, referring to black edging on all or most fins. (See ETYFish).

Biology     Glossary (e.g. epibenthic)

A little-known deepwater dogfish found on the upper continental slopes to at least 450 m (Ref. 31367). Ovoviviparous (Ref. 50449). Probably taken in bottom trawls (Ref. 31367). Caught by demersal longline fisheries operating in deepwater areas. Utilised for its meat, fins (low value) and liver oil (very high value) (Ref.58048).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205). Gives birth to a single pup. Born at 28-36 cm TL (Ref.58048).

Estimates based on models

Preferred temperature (Ref. 123201): 11.2 - 18.8, mean 14.2 °C (based on 105 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00263 (0.00121 - 0.00572), b=3.18 (2.99 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.3   ±0.3 se; based on size and trophs of closest relatives
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 (55 of 100).
