Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 87.0 cm TL maschio/sesso non determinato; (Ref. 31367)
Spine dorsali (totale) : 2; Spine anali: 0. Adults with tips of dorsal fins black, prominently marked from base of fins (Ref. 31367).
Body shape (shape guide): elongated.
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).
