Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 55 - 63; Anal spines: 0; Anal soft rays: 37 - 42. Pelvic fins with 6 rays (females), absent in males.

Mesopelagic species (Ref. 75154). Pronounced sexual dimorphism: females are black, with well developed canine teeth, barbel and pelvic fins with six stripes. Males are dark-brown, have no teeth on maxilla and neither barbel nor pelvic fins (Ref. 47377). Apparently, females live below 500 m during the day and perform vertical migration at night to shallower depths; males always in deep water, ca 1,000-2,000 m (Ref. 5169).
