Ecologia
marinhas batipelágico; intervalo de profundidade 180 - 2600 m (Ref. 58426), usually 400 - 1200 m (Ref. 1371). Deep-water; 73°N - 20°N, 77°W - 32°E
North Atlantic: from about 37°N to Baffin Island and Greenland in the western Atlantic, and off Iceland and Norway to 73°N to Barents Sea, south to North Africa in the eastern Atlantic. Reported to occur from the tongue of the Ocean east of Andros Islands (about 24°N, 77°W) in the Bahamas.
Comprimento de primeira maturação / Tamanho / Peso / Idade
Maturity: Lm 52.7, range 60 - ? cm
Max length : 110 cm TL macho/indeterminado; (Ref. 35388); peso máx. publicado: 1.7 kg (Ref. 40637); idade máx. registrada: 54 anos (Ref. 41452)
Espinhos dorsais (total) : 2; Espinhos anais: 0. Head broad, rather soft; snout broad, rounded, with a large blunt tubercular scute at its tip; chin with small barbel. Scales relatively adherent; spinules dense on body scales, long, thin and recurved, narrowly lanceolate, with longitudinal anterior concavity. Pyloric caeca 29 to 31, long and slender. Color medium brown to grayish; orbits, oral and branchial cavities, and fins blackish to brownish gray.
Benthopelagic to bathypelagic in about 400 and 1200 m depth. Minimum depth from Ref. 1371. Form large schools at 600 to 900 m depth (Ref. 9988). Feed on a variety of fish and invertebrates, but primarily on pelagic crustaceans such as shrimps, amphipods and cumaceans; cephalopods and lantern fishes constitute a lesser portion of the diet. Batch spawner (Ref. 51846). This species is currently facing overexploitation in the North Atlantic. Utilized frozen and for fishmeal; can be fried and baked (Ref. 9988).
