Southwest Pacific: Western Australia to New South Wales, including New Zealand. Principal component analysis of morphometric and meristic characters indicates three separate subpopulations in the Great Australian Bight, off New South Wales, and off Tasmania (Ref. 7456).

Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 9; Dorsal soft rays (total): 29 - 35; Anal spines: 3; Anal soft rays: 24 - 29; Vertebrae: 24. Adults are elongate and slightly compressed, and have a primary lateral line with 71-89 scutes, and a secondary lateral line reaching to below dorsal-fin rays 7-9 (Ref. 33616).
Adults are commonly found near the bottom, in midwater and occasionally at the surface (Ref. 9258) in continental shelf waters (Ref. 27930). They form pelagic schools for most of the year but may move close to the sea bed during winter (Ref. 27931). Generally found at less than 300 m water depth with temperature less than 16° C (Ref. 9072). Juveniles inhabit coastal and estuarine waters although they may sometimes be found offshore (Ref. 27930). Adults feed mostly during the day mainly on krill and other planktonic crustaceans, light fish (Sternoptychidae) and lantern fish (Myctophidae) at the edge of the continental shelf (Ref. 27933).
Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Eggs and sperm are released amongst schooling fish, possibly deep in the water column near the edge of the continental shelf. Eggs are distributed between the surface and the thermocline and larvae are carried inshore by currents.

Estimates based on models
Preferred temperature (Ref. 115969): 11.1 - 20.2, mean 14.4 (based on 135 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00784 - 0.02022), b=2.97 (2.83 - 3.11), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.9 ±0.61 se; based on food items.
Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=2-4; tmax=25).
Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).
Climate Vulnerability (Ref. 125649): Moderate vulnerability (36 of 100).
