(See ETYFish);  attenuatus: Latin for drawn out or tapered, refer- ring to its “attenuate, almost anguilliform as though emaciated” shape. (See ETYFish).

Short description Khóa để định loại | Hình thái học | Sinh trắc học

Các tia vây lưng cứng (tổng cộng) : 0; Tia cứng vây hậu môn: 0. Caudal fin without a rippled dorsal margin and ventral lobe but with a strong subterminal notch; vertebral axis of caudal fin little raised above body axis (Ref. 13566).

Sinh học     Tự điển (thí dụ epibenthic)

An uncommon to common deep-water bottom-dwelling shark found on the outermost continental shelf and upper slope of New Zealand and on adjacent seamounts and submarine banks (Ref. 13566). Seems adapted to waters of about 10°C and 34.8 ppt salinity (Ref. 6893). Feeds on a wide variety of fishes, cephalopods, and other invertebrates (Ref. 13566). Probably in schools (Ref. 13566). Females grow slightly larger than males (Ref. 13566). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother, uterine milk is consumed additionally (Ref. 50449). Two young are born per litter (Ref. 13566).

Life cycle and mating behavior Maturities | Sự tái sinh sản | Spawnings | Egg(s) | Fecundities | Ấu trùng

Exhibit ovoviparity (aplacental viviparity), embryos feed on yolk and ova, also consume uterine milk (Ref. 50449). With usually 2 young per litter (Ref. 13566). Fetuses eat unfertilized eggs and store consumed yolk in their yolk sacs (Ref. 13566). Distinct pairing with embrace (Ref. 205).
