Short description Morphology | Morphometrics

A black-spotted longnose skate with an elongated, acutely triangular snout, and a stout tail- just shorter than body and slightly swollen along the mid-section; disc with rounded corners and smooth underside except for small denticles on edges and tip of snout; small thorns on nape and midback to 1st dorsal fin (Ref. 5578). Medium grey to brownish with numerous small dark spots dorsally; grey with conspicuous black pores ventrally (Ref. 5578).

Biology     Glossary (e.g. epibenthic)

Found on the bottom of the outer shelf and upper slope (Ref. 5578). Probably caught by trawlers (Ref. 5578).Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Males reaches maturity at ca. 57 cm TL, females at ca. 64 cm TL (Ref. 114953)

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

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): 8.8 - 21.2, mean 14.4 °C (based on 4 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).
Trophic level (Ref. 69278):  3.8   ±0.6 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 (46 of 100).
