Écologie
marin bathydémersal; profondeur 39 - 1200 m (Ref. 117245), usually 71 - ? m (Ref. 117245). Deep-water; 0°C - 5°C (Ref. 35388); 74°N - 61°N, 72°W - 45°W (Ref. 117245)

Taille / Poids / Âge
Maturity: Lm ?  range ? - ? cm
Max length : 52.0 cm TL mâle / non sexé; (Ref. 4695); common length : 27.5 cm TL mâle / non sexé; (Ref. 4695)
Dorsal fin without depression, front end with 0-3 black - brown spots. Lateral line runs near the anal fin (Ref. 35388).
Lives at temperature of 0-5°C. Off Greenland it measures 50 cm and off Scandinavia rarely over 25-30 cm (Ref. 35388). Benthic (Ref. 58426). Feeds mostly on endobenthic prey, with shrimps and euphausiids becoming the more prominent prey as the size increases (Ref. 13532). Prefers warmer waters (Ref. 13534). Large eggs of 6 mm diameter are deposited on the sea floor.
