Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0. A large, fairly stocky, catshark with large and small black spots and sometimes white spots covering dorsal surface, saddle markings obsolete, small anterior nasal flaps that do not reach the mouth, no nasoral grooves, labial furrows on lower jaw only, second dorsal fin much smaller than first (Ref. 244)

A common inshore and offshore shark found on the continental shelf over rough, even rocky or coralline ground, and algal-covered bottoms. Found at depths of 1 or 2 m to at least 125 m. Feed on bottom-living invertebrates such as mollusks and crustaceans and on demersal fishes (e.g. sharks, S. canicula). Oviparous (Ref. 50449). Utilized fresh and dried salted for human consumption, and processed into fishmeal. May attain 170 cm (Ref. 27000).

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

Oviparous, with a single egg per oviduct (Ref. 244). Embryos feed solely on yolk (Ref. 50449). Size at hatching about 16 cm (Ref. 244).
