Environment / Climate / Range
Marine; bathydemersal; depth range 90 - 750 m (Ref. 9917). Deep-water
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 60 - ? cm

Eastern Indian Ocean: southern Australia, from Port Headland to Tasmania and off the Swain Reefs in Queensland. Torpedo macneilli is similar and probably synonymous with Torpedo fairchildi from New Zealand (Ref. 12951).
An offshore species found on continental shelves and slopes (Ref. 9917, 75154). Found near rocky reefs, over sand and mud bottoms (Ref. 12951). Feeds on fishes and crustaceans (Ref. 12951). Ovoviviparous (Ref. 50449). Capable of severely shocking people if handled (Ref. 9917).
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).
