Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 5 - 1153 m (Ref. 26346). Deep-water
Southwest Pacific: endemic to New Zealand. Specimens recently seen at Norfolk Island may be this species. Torpedo macneilli from Australia is very similar to this species (Ref. 6871).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 100.0 cm TL male/unsexed; (Ref. 26346)
Morphology | Morphometrics
Dark grey dorsally, white ventrally (Ref. 26346).
Found on the continental shelf and upper slope (Ref. 26346). Feeds on fish, probably at night (Ref. 26346). Ovoviviparous (Ref. 50449).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).
