Short description
Identification keys | Morphology | Morphometrics
Mesopelagic to bathypelagic. Carnivorous. Probably spawns near the surface in temperate to tropical waters (Ref. 5759). Has been supposed to be one of the 'cable-biters'; reconstructions from big teeth found in submarine cables suggests that it attains at least 100 cm body-length (Ref. 4474).
