Morphology | Morphometrics
spines: 0. Head profile rounded; snout short, blunt. Scales deciduous, with 1 to 3 divergent rows of small, thin spinules uniformly covering almost all of the body; scales absent over most of the snout and in wide patches on the head surrounding large pores of sensory lateralis system. Pyloric caeca rather long and slender, about 9 to 10. Overall color is dark brown to brownish black.
Southern Ocean: circumpolar, extending north of Convergence in some areas.
Feeds on fish, copepods and other small invertebrates (Ref. 5097).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00128 - 0.00712), b=3.12 (2.93 - 3.31), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.40 se; Based on food items.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (55 of 100) .
