Short description Morfologi | Morfometri

An all-dark longnose skate with a greatly elongated, broadly triangular snout, and a stout tail - shorter than body and with mid-section swollen and triangular-shaped; disc with angular corners and smooth underside; small thorn at nape (Ref. 5578). Uniform dark grey above and below with black mucous pores on the underside (Ref. 2708, 5578).

Biologi     Ordlista (t.ex. epibenthic)

Found on upper and mid-continental slope (Ref. 114953). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Males reaches maturity at ca. 83-98 cm TL; smallest known specimen at 24 cm TL; hatching size possibly at ca. 24 cm TL (Ref. 114953).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 9.7 - 12.9, mean 11.5 °C (based on 27 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Låg, lägsta populationsfördubblingstid 4,5-14 år (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High vulnerability (61 of 100).
