Tamaño / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 87.0 cm TL macho / no sexado; (Ref. 31367)
Espinas dorsales (total) : 2; Espinas anales: 0. Adults with tips of dorsal fins black, prominently marked from base of fins (Ref. 31367).
A little-known deepwater dogfish found on the upper continental slopes to at least 450 m (Ref. 31367). Ovoviviparous (Ref. 50449). Probably taken in bottom trawls (Ref. 31367). Caught by demersal longline fisheries operating in deepwater areas. Utilised for its meat, fins (low value) and liver oil (very high value) (Ref.58048).
Life cycle and mating behavior
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
