Short description Morfología | Morfometría

Relatively slender, moderately long, narrow snout and relatively narrow, low caudal fin. Color uniform dark brown (Ref. 37039). First to third gill openings long as the distance between the nostrils (Ref. 6032).

Biología     Glosario (por ej. epibenthic)

Found on the continental slopes. Oviparous, with one egg per oviduct laid at a time. Sexual dimorphism in adults unusually well-developed.

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Sexual dimorphism is evident in dentition of males (Ref. 49562). Males have longer teeth with fewer cusps (Ref. 51093) to make 'courtship biting' more effective (Ref. 49562).
