Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathypelagic; depth range 200 - 5301 m (Ref. 58426), usually 500 - 2700 m (Ref. 82363). Deep-water; 67°N - 45°S, 180°W - 180°E

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Widely distributed in all Atlantic, tropical and austral Indian and Pacific Oceans (Ref. 4463). Southern Ocean: probably circum-Antarctic between the Antarctic Polar Front and the Antarctic continental shelf (Ref. 5162).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 15; Anal spines: 0; Anal soft rays: 17 - 20. Brown to brown-black in color; dense stellate pigment over head, body and fins (Ref. 3991).

Biology     Glossary (e.g. epibenthic)

An oceanic, deep mesopelagic to bathypelagic species (Ref. 4769). Precise depth range dependent upon developmental stage, latitude, season (Ref. 4769). Doest not exhibit diel vertical migrations (Ref. 4769). A non-seasonal breeder with no recognizable age-cohorts (Ref. 82363). Feeds mainly on copepods (Ref. 4769).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Protandrous, sex reversal observed in the eastern North Atlantic (Ref. 5162). Sex reversal at 22-24 mm SL (Ref. 4769).

Estimates based on models

Preferred temperature (Ref. 123201): 1.8 - 8.2, mean 3.2 °C (based on 7820 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00172 - 0.00881), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.13 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm>1; Fec=2,000-10,000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
