Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 17; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 11 - 13. Body deepest ahead of dorsal fin. Head depressed and bony, mouth large, teeth conical, recurved and mostly depressible (Ref. 39983). Preserved specimens, dark ventrally (Ref. 11228).
Usually occurs below the 4°C isotherm. Rests stationary on the bottom with head slightly elevated in typical lizardfish fashion. Feeds primarily on fish and decapods (Ref. 4964). Synchronously hermaphroditic. Minimum depth reported from Ref. 5755.
