Size / Weight / Age

Max length : 100.0 cm TL male/unsexed; (Ref. 244); common length : 60.0 cm TL male/unsexed; (Ref. 4645); max. published weight: 1,320 g (Ref. 40637); max. reported age: 12 years (Ref. 81067)

Environment

Demersal; marine; depth range 10 - 780 m (Ref. 56504), usually 80 - 100 m (Ref. 81056)

Climate / Range

Subtropical; 63°N - 12°N, 18°W - 36°E

Northeast Atlantic: Norway and British Isles south to Senegal, including the Mediterranean. Possibly Côte d'Ivoire. Some populational differences exist between Catulus duhameli (a name for the Mediterranean canicula based on size) and this species which may eventually be expressed as subspecies. The only reported observation of this species in Crimean waters was in 1937, which is possibly erroneous (Ref. 897).

Short description

Dorsal spines (total): 0; Anal spines: 0. A slender, dark-spotted catshark with greatly expanded anterior nasal flaps, reaching mouth and covering shallow nasoral grooves, labial furrows on lower jaw only, second dorsal fin much smaller than first (Ref. 244)

Inhabit continental shelves and uppermost slopes. Depth range from 10-400 m (Ref. 244), and from 288-780 in the eastern Ionian Sea (Ref. 56504). Found on sandy, coralline, algal, gravel or muddy bottoms at depths of a few meters commonly down to 110 m. They sometimes occur in midwater. Feed on mollusks and crustaceans, small cephalopods, polychaete worms, and small bony fishes. Oviparous, with a single egg laid per oviduct at a time. Utilized fresh and dried-salted for human consumption, also for oil and fishmeal.
