Short description Morfología | Morfometría

Very broad, almost pentagonal disc, light above and abruptly dark below; snout bluntly pointed with a flexible tip, eyes small and close together, and a disc with broadly rounded rear margins and tips (Ref. 5578). Small juveniles with and adults without thorns and covered only with small denticles (Ref. 5578). Slate-grey or greyish-brown above except rear margins of pectoral and pelvic fins and claspers of adult males which are dark brown; dark brown below, sometimes with light blotches (Ref. 5578). Lack of large thorns on its disc posterior to the scapular region (Ref. 6902).

Biología     Glosario (por ej. epibenthic)

A very rare species inhabiting continental slopes and probably down to the abyssal plains (Ref. 3167). Benthic (Ref. 58426). Adults usually at depths greater than 1,500 m while juveniles are mainly taken from about 450 m downward (Ref. 4426). Minimum depth reported taken from Ref. 4426. Feeds on crustaceans (Ref. 58426). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

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

Oviparous (Ref. 3167). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449).
