Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 20 - 22; Raggi dorsali molli (totale) : 19 - 24; Spine anali: 2; Raggi anali molli: 18 - 21; Vertebre: 34 - 36. Body fairly elongate and strongly compressed. Mouth with fang-like teeth. The tips of both jaws with dermal processes. Gill rakers degenerated. Color is dark brown with violet tint; fin membranes black; margin of anus black (Ref. 6181).

Biologia     Glossario (es. epibenthic)

Adults, benthopelagic to mesopelagic, dwell on the continental slope or underwater rises, migrating to midwater at night (Ref. 6181). Eggs are pelagic (Ref. 6766). Larvae and juveniles, epipelagic to mesopelagic, are rather common in oceanic ichthyoplankton and are only found in the tropics (Ref. 6181). Feed on squid, fish and crustaceans (Ref. 6181). Consumed as food (Ref. 4537).
