Short Description
A giant skate with a broad-based, abruptly narrow-tipped snout covered with small, sharp thorns; pectoral disc angular, and no thorns on nape or back, but three rows of large thorns on tail [536]. Larger immature and adult individuals grey with numerous small white spots above, underside white with no black pores; hatchlings plain reddish-brown above, often with blue spots, and white below with broad dusky grey margins on disc [536].

Distribution
Eastern Atlantic: Ireland and England southward round the Cape (South Africa) to central Mozambique [536], including western Mediterranean (to Tunisia and western Greece). Source: www.gbif.org

Human uses
fisheries: minor commercial; gamefish: yes; price category: medium; price reliability: very questionable: based on ex-vessel price for species in this family

Biology
Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Eggs are laid in huge cases and take up to 18 months to hatch [536]. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother [17086].

demersal; marine; depth range 30 - 600 m [17687], usually 50 - 500 m [20084]
