Etymology: Aethotaxis: Greek, aethia, = unusual + Greek, taxis = disposition (Ref. 45335); mitopteryx: The specific name is derived from the Greek word mitos (thread or string) and pteryx (wing), referring to the filamentous nature of the first dorsal spines and pelvic rays (Ref. 11892).

Southern Ocean: islands of the Scotia Sea, Weddell Sea, Prydz Bay and the Ross Sea. A separate subspecies may be present in the Ross Sea population, but this needs more evidence (Ref. 5179). Reported from Olaf Prydz Bay, Mackenzie Sea, Indian sector of the Antarctic (Ref. 44178).

Maturity: L_m ? range ? - ? cm
Max length : 44.3 cm TL mâle / non sexé; (Ref. 124149); 33.6 cm TL (female); poids max. publié: 563.60 g (Ref. 124149)

Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 7; Rayons mous dorsaux (Total) : 34; Rayons mous anaux: 30. Gray with violet hue and lighter below with metallic luster. In alcohol, purplish gray or light brown dorsally (Ref. 11892).

Feeds on zooplankton. The storage of lipids in cells of adipose tissue as well as the reduced calcification of the skeleton provide buoyancy to this species.

Estimates based on models

Preferred temperature (Ref. 115969): -0.2 - 1.2, mean 0.9 (based on 21 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00525 (0.00328 - 0.00839), b=3.10 (2.96 - 3.24), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.45 se; based on food items.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (68 of 100).
