Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 17; Espinas anales: 0; Radios blandos anales: 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).
Body shape (shape guide): elongated.
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.
