Écologie
marin benthopélagique; profondeur 10 - 400 m (Ref. 58426), usually 10 - 30 m (Ref. 35388). Temperate; 72°N - 49°N, 70°W - 32°E
Northeast Atlantic: Norwegian coast to Finmarken and Waranger Fjord, occasionally Murman coast, rare in Skagerrak, Kattegat and Öresund, around Helgoland, also British Isles; also the Orkneys, Faroes, Shetlands and Iceland (Ref. 4782). Northwest Atlantic: Canada (Ref. 7251).
Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 25.0 cm SL mâle / non sexé; (Ref. 4782); 18.0 cm TL (female); common length : 17.5 cm SL mâle / non sexé; (Ref. 4782)
Épines dorsales (Total) : 50 - 54; Rayons mous dorsaux (Total) : 0; Rayons mous anaux: 35 - 40. Snout blunt; mouth frog-like. With a large fringed tentacle above each eye, a smaller one in front and others on top of head and on the anterior dorsal fin spines. First anal fin ray a short flexible spine. Lateral line represented by a dorsal and a mediolateral branch of neuromasts (the former begins as a short canal, with 4-5 pores.
