Short description Chiavi di identificazione | Morfologia | Morfometria

A pale-spotted longnose skate with an elongated, acutely triangular snout, and a very slender tail- as long as body and tapering from base to tip; disc with angular corners and smooth underside except of small denticles on edges and tip of snout; thorns on upper surface of disc and tail conspicuously lighter than surrounding skin; spine at nape (Ref. 5578). Dark grey with numerous small light spots dorsally; grey with black pores ventrally, and with light areas around gills and at front of edge of disc (Ref. 5578).

Biologia     Glossario (es. epibenthic)

Probably taken by offshore trawlers (Ref. 5578). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

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

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
Resilienza (Ref. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (53 of 100).
