Etymology: Gymnoscopelus: Greek, gymnos = naked + Greek, skopelos, a lantern fish (Ref. 45335).
Eponymy: Professor Dr August Bernhard Brauer (1863–1917) was a German herpetologist and ichthyologist. [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; bathypelagic; oceanodromous (Ref. 51243); depth range ? - 2700 m (Ref. 58018). Deep-water; 33°S - 78°S
Generally ranges between the coasts of Antarctic and 33°S (south-western Atlantic Ocean sector), 46°S (Indian Ocean sector between 50°-71°E), and about 46°S (Pacific Ocean sector off Chile).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 22.0 cm SL male/unsexed; (Ref. 128038)
Oceanic and mesopelagic, found in the upper 200 m at night but deeper in the region of Subtropical Convergence (Ref. 4066). Feeds mainly on Euphausia superba; also takes copepods (Euchaeta antarctica, Rhincalanus gigas), amphipods (Primno macropa, Themisto gaudichaudii) and the euphausiid Thysanoessa macrura.

Estimates based on models
Preferred temperature (Ref.
123201): -1.5 - 2.3, mean 0.8 °C (based on 693 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00437 (0.00200 - 0.00953), b=3.16 (2.96 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.3 se; based on diet studies.
Generation time: 3.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (34 of 100).
Nutrients (Ref.
