Description

The nursehound is a bottom-dwelling catshark of the family Scyliorhinidae reaching about 170 cm. The elongate body is covered with large and small black spots, sometimes with white flecks as well. There are two dorsal fins set far back, and the skin feels rough. The nursehound lives solitarily on rocky and rough bottoms of the north-eastern Atlantic and Mediterranean, usually between 20 and 60 m, hunting benthic invertebrates and fish at night. It is oviparous, laying leathery egg cases ('mermaid's purses'). Fishing pressure has left the species assessed as Vulnerable across much of its range.
