Short description Morfología | Morfometría

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).

Biología     Glosario (por ej. 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 Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

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

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 9.7 - 12.9, mean 11.5 (based on 27 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00128 - 0.00621), b=3.24 (3.06 - 3.42), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.9   ±0.6 se; Based on size and trophs of closest relatives
Resiliencia (Ref. 69278):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).
