Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 54 - 59; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 18 - 21. Eyes relatively large, greater than snout length in diameter. Anal fin originating near midlength of body, deeply indented at midlength, sometimes appearing as two. Ventral light organ absent. Color is generally gray.
Recorded from the upper continental slope (Ref. 9563). Occasionally found at 50 m. Feeds on fishes, crustaceans, mollusks and other invertebrates as well as food of terrestrial origin, including garbage. Probably a winter and early spring spawner (Ref . 4774). Minimum depth from Ref. 106682.
