Northeast Atlantic: Iceland to the British isles, it was formerly more widespread, including the Mediterranean Sea and North Africa, but its range is thought to be reduced due to fishing.

Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos anais: 0. This species is characterized by the following: snout long and pointed, length 3.7-5.1 times orbit length; disc broadly rhombic, anterior margin deeply concave; a row of 12-18 predorsal thorns in median row along tail (disc smooth in young); lateral thorns on tail pointed towards head; interspace between dorsal fins (2.4 ± 0.5 TL); upper surface dark olive-green in young with small pale spots, becoming greyish-brown; underside greyish or whitish; iris olive green (Ref. 114953, 127223).

Biologia     Glossário (ex. epibenthic)

A benthic species found in shelf and slope waters, mainly within the 200 m range but occasionally down to 1,500 m (Ref. 114953, 127218, 127220, 127222). Feeds on all kinds of bottom invertebrates and fish, including other skates (Ref. 114953). Oviparous, with long embryonic development. Males reach maturity at ca. 185 cm TL, females at 197 cm TL; birth size at ca. 29 cm TL, from large egg cases (up to 25 cm) (Ref. 114953). Biology unclear due to past taxonomic confusion.

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).
Nível Trófico (Ref. 69278):  4.1   ±0.6 se; based on size and trophs of closest relatives
Resiliência (Ref. 120179):  Muito baixo, tempo mínimo de duplicação da população maior que 14 anos (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
