Depth range: 0-5 m on rocky bottoms. Usually under rocks; rarely under algal fronds. A specialized feeder on amphipods, mainly Gondogeneia antarctica. Feed on small crustaceans and common in littoral of all sub-Antarctic islands (Ref. 42041). Iteroparous and devotes a lot of time to parental care (Ref. 5191).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00206 - 0.01336), b=3.10 (2.88 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.3 ±0.53 se; based on food items.
Generation time: 4.4 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Weerstandsvermogen (Ref.
120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Fec = 400).
Fishing Vulnerability (Ref.
