deskripsi pendek
Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)): 0; duri punggung lunak (Keseluruhan (total)): 65-82; Duri dubur 0; Sirip dubur lunak: 50 - 65; vertebrata, bertulang belakang: 39 - 42. Dorsal origin over forward part of eye. Caudal with posterior margin a broad 'V'. Pectorals small and may be asymmetrical (Ref. 6885). Blind side white, with glossy highlights along myotome margins, increasing anteriorly. Pores: supraorbital 3-9; preopercular 5-7; lateral line 70-91. Interorbital space narrow (Ref. 37594).
Adults occur over sand and gravel substrates to depths of 339 m; larvae collected over depths less than 1,000 m (Ref. 37594). Feed on mollusks, polychaete worms, crustaceans, brittle stars, and fishes (Ref. 6885). A tasty food fish; in some years commercial catch in Canada reaches 3,000 t (Ref. 2850).
