Short description

Dorsal spines (total): 5 - 7; Dorsal soft rays (total): 33-36; Anal spines: 2-3; Anal soft rays: 31 - 34; Vertebrae: 40 - 43. First dorsal spine longer than second dorsal spine. Opercles fully scaled (Ref. 27159). Female adult chocolate brown in color with darker fins; prejuveniles silvery with numerous dark spots of various sizes which become larger with age (Ref. 6548).

Inhabit continental slopes of all southern continents (Ref. 6545). Adults found near the bottom; juveniles near the surface, usually in association with krill (Ref. 5194). Feed mainly on salps (Ref. 27150). Eggs float near the sea surface and larvae also inhabit surface waters (Ref. 6390). There is no vertical migration during the day or night (Ref. 27150).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805)
PD₅₀ = 1.0010 many relatives (e.g. carps) 0.5 - 2.0 few relatives (e.g. lungfishes)

Trophic Level (Ref. 69278)

Resilience (Ref. 69278)
Very Low, minimum population doubling time more than 14 years (K=0.07; tmax=100; tm=31; Fec=6,000)
