Short description Morphology | Morphometrics

Dorsal soft rays (total): 9-10; Anal soft rays: 30 - 32; Vertebrae: 79 - 84. A species of Arctozenus differing from the only congener in having a pale body with lower half mostly devoid of chromatophores; body slender, its depth 14-19 in SL; a slender head, its depth at middle of eye 4.3-5.1 in HL. Compared to similar size specimens (>250 mm SL) of A. risso, A. australis has relatively slender body (5.2-7.3%, vs. 7.7-10.6% SL); the ratio of snout length/eye diameter relatively large 3.1-3.9 (vs. 2.7-3.4); origin of pelvic fin slightly but clearly behind dorsal-fin base (vs. usually below dorsal-fin base); and anterior lateral-line scales long, about twice as long as its height (vs. width subequal to the height). (Ref. 122005)

Biology     Glossary (e.g. epibenthic)

Reported as by-catch of bottom trawl on the slope of the Kerguelen Plateau (480-800 m) and South-Georgia (Ref. 122005).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00224 (0.00090 - 0.00555), b=3.14 (2.92 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.7 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100).
