Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 17; Anal spines: 0; Anal soft rays: 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).

Biology     Glossary (e.g. epibenthic)

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.
