Size / Вес / Возраст
Maturity: Lm ? range ? - ? cm
Max length : 87.0 cm TL самец/пол неопределен; (Ref. 31367)
колючие лучи спинного плавника (общее число) : 2; колючие лучи анального плавника: 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
Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки
Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205). Gives birth to a single pup. Born at 28-36 cm TL (Ref.58048).
