Description. Body shape eel-like, moderately compressed, elongated and attenuated to the caudal peduncle; scales absent on top of head and opercle; the pre-oral length is very short and is contained 3–5.3 times in the snout length; palatine tooth patch separated from pterygoid by a distance 0.7–1.7 times its length; first dorsal ray very short and vestigial; dorsal fin origin posterior to pelvic fin origin; anal opening white, surrounded by a ring of darkly pigmented tissue; pyloric caeca black. The main morphometric and meristic characteristics are presented in Table 8.

Habitat and distribution. Benthopelagic to benthic on the lower slope, continental rise and upper abyss, between 1,100 and 3,300 m depth and primarily between 2 and 4ºC isotherm (Sulak 1990). Circumglobal at tropical and temperate latitudes. Western Atlantic, from Canada to Venezuela and Guyana; eastern Atlantic, off northwestern Africa, Azores Islands and the Gulf of Guinea (Sulak 1977, 1990); Indian Ocean, from Saya-de- Malaya Bank and the East Indian Range (Filatova 1985), and eastern, central and northern Pacific Ocean and waters off of Chile (Froese & Sampang 2004; Kamikawa & Stevenson 2010; Hanke et al. 2014).
