Espinas dorsales (total) : 0; Espinas anales: 0. A large, plain or black-spotted smoothhound (Ref. 5578). Uniformly grey or greyish-brown above, white below (Ref. 5578).
Body shape (shape guide): elongated.
Found on the continental shelves and uppermost slopes, from the intertidal region to at least 350 m depth (Ref. 244). Collected to depth of 624 m in the eastern Ionian Sea (Ref. 56504). Sometimes in midwater but prefers to swim near the bottom (Ref. 244). Feeds mainly on crustaceans, but also cephalopods and bony fishes (Ref. 244). Viviparous, with a yolk-sac placenta (Ref. 244). Taken by shore and ski-boat anglers (Ref. 5578). Utilized for human consumption, oil, and fishmeal (Ref. 244). Sexual maturity is reached at a length of 70-80 cm (Ref. 35388).
Viviparous, with a yolk-sac placenta; 4 to 17 (Ref. 39938) young in a litter. Size at birth about 39 cm. Distinct pairing with embrace (Ref. 205).
