Etymology:

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathydemersal; depth range 5 - 1153 m (Ref. 26346). Deep-water

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

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)

Short description Morphology | Morphometrics

Dark grey dorsally, white ventrally (Ref. 26346).

Biology     Glossary (e.g. epibenthic)

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).

Estimates based on models

Preferred temperature (Ref. 123201): 9.5 - 14.1, mean 12 °C (based on 33 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00659 - 0.03318), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.80 se; based on food items.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (60 of 100).
