(See ETYFish);  bruniensis: -ensis, Latin suffix denoting place: the shore of Bruny Island, Tasmania, where holotype was discovered in a “dried … but fair state of preservation”. (See ETYFish).

Southwest Pacific: confined to temperate waters off southern Australia and New Zealand.

Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 60 - ? cm
Max length : 65.0 cm TL male/unsexed; (Ref. 122636); 74.0 cm TL (female); max. published weight: 6.6 kg (Ref. 122636)

Short description Morphology | Morphometrics

Anal spines: 0; Anal soft rays: 0. Uniform grey-brown coloration; short, blunt snout; high sail-like dorsal fins with spines and broad apices, first dorsal spine inclined backward; high, thick triangular body with large, rough denticles; circular spiracles; lanceolate upper teeth, lower blade-like teeth in less than 12 rows (Ref. 247).

Biology     Glossary (e.g. epibenthic)

Found on outer continental and insular shelves and uppermost slopes (Ref. 247). Probably feeds on bottom invertebrates and fishes. Ovoviviparous (Ref. 205). Taken incidentally with bottom trawls but probably not used (Ref. 247).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Ovoviviparous, with 7 young in a litter (Ref. 247). Size at birth about 24 cm (Ref. 6871). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 6.2 - 10.4, mean 8 °C (based on 150 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00160 - 0.00860), b=3.15 (2.94 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.62 se; based on food items.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Fec=7).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100).
Nutrients (Ref. 124155):  Calcium = 8.32 [1.56, 44.88] mg/100g; Iron = 0.283 [0.065, 0.939] mg/100g; Protein = 18.8 [17.0, 20.6] %; Omega3 = 0.302 [0.100, 0.969] g/100g; Selenium = 14.1 [4.0, 44.8] μg/100g; VitaminA = 13.4 [2.6, 67.1] μg/100g; Zinc = 0.414 [0.198, 0.828] mg/100g (wet weight);
