Maturity: Lm ?  range ? - ? cm
Max length : 6.7 cm SL male/unsexed; (Ref. 5182)
High-oceanic and mesopelagic (Ref. 4066). Found between 608-728 m during the day and between 364-426 m at night (Ref. 4066). Feeds on copepods and larval stages of krill, mainly calytopis and furcilia stages. Recorded from the stomach contents of Lepidonotothen squamifrons.

Estimates based on models
Preferred temperature (Ref. 115969
): -0.6 - 1.8, mean 0.9 °C (based on 288 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00423 - 0.02478), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.0 se; based on diet studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100) .
