دريايي موجوداتی که در محدوده وسیعی از آبهای آزاد از نزدیک بستر و یا روی کف بستر، در قسمت های میان آبی تا سطح آب و در برخی گونه ها با قابلیت پرواز، زندگی و تغذیه می کنند.; تغييرات عمق 125 - 3285 m (Ref. 58426), usually 128 - 1000 m (Ref. 117245). Deep-water; 61°N - 50°S, 180°W - 180°E
Worldwide except in tropical waters (Ref. 27363). North Atlantic: Gulf of Mexico and Cape Blanc, Mauritania north to Davis Strait, Canada and Iceland. South Atlantic: off South Africa. Southeast Pacific: off Chile. Eastern Indian Ocean: Australia (Ref. 7300). Southwest Pacific: New Zealand (Ref. 5755).
Size / Weight / سن
Maturity: Lm ? range ? - ? cm
Max length : 120 cm TL جنس نر / بدون خواص جنسي; (Ref. 4449)
خارهاي باله پشتي (کل): 5 - 12; شعاع نرم باله پشتي (کل): 2; خارهاي باله مخرجي 14-17; شعاع نرم باله مخرجي: 125 - 145; مهره ها: 225 - 239. Presence of palatine and dentary teeth in two or more rows. Numerous dorsal spines. Small specimens are pale tan or pale bluish gray, large specimens are dark brown (Ref. 37108).
Benthopelagic (Ref. 58302) and epibenthic (Ref. 58426). Not uncommon in depths around 180 m off Iceland and Greenland. Individuals with nearly ripe eggs have been found in late autumn off Iceland. Mostly found at depths well below 200 m, but enters slightly shallower water on Grand Banks in Canada (Ref. 7251). Feeds primarily on sea anemones (Ref. 4449).
