Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 75 - 89; Anale stekels: 0; Anale zachte stralen: 60 - 71. Dark spots on ocular side irregularly and two dark small spots at end of both dorsal and anal fin bases on blind side symmetrically (Ref. 27363).

Feeds on amphipods, small crabs and polychaetes (Ref. 36453). In spring mature individuals migrate to 37°S and southwards to spawn and in autumn migrate offshore for feeding and growing (Ref. 41500).

Estimates based on models

Preferred temperature (Ref. 123201): 6.3 - 22.9, mean 12.1 °C (based on 642 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00427 (0.00264 - 0.00688), b=3.22 (3.08 - 3.36), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.3 ±0.49 se; based on food items.

Generation time: 2.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (45 of 100).

Xystreurys rasilis (Jordan, 1891)
