Circumglobal distribution in the region of the Subtropical Convergence, but may be absent over the region 115°W to the coast of Chile. Eastern Atlantic: known from the southern boundary limit, 23°S to 21°S but probably farther to the north in the Benguela Upwelling Region. Southwest Atlantic: between 32°S and 46°S (Ref. 47377).

Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 15; Anal spines: 0; Anal soft rays: 12 - 14.

Oceanic and mesopelagic (Ref. 4066). Taken as prey by hakes, kingklip and Cape horse mackerel (Ref. 36731). Found in the upper 250 m at night. Spawns in spring-early summer. Reach sexual maturity at a length of 3,6 cm (Ref. 47377).

Estimates based on models

Preferred temperature (Ref. 123201): 11.8 - 18.8, mean 15.7 °C (based on 7 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00328 - 0.01756), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.00 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
