Length at first maturity / Μέγεθος / Βάρος / Age
Maturity: Lm ?, range 34 - ? cm
Max length : 80.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 9563); common length : 45.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 9258)
Ραχιαίες άκανθες (συνολικά): 0; Μαλακές ραχιαίες ακτίνες (συνολικά): 54-59; Εδρικές άκανθες 0; Μαλακές εδρικές ακτίνες: 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.
