Teleostei (teleosts) > Myctophiformes (Lanternfishes) > Myctophidae (Lanternfishes) > Gymnoscopelinae
Etymology: Notoscopelus: Greek, noton = back + Greek, skopelos = a lantern fish (Ref. 45335).
Eponymy: Henrik Nikolai Krøyer (1799–1870) was a Danish marine biologist. [...] (Ref. 128868), visit book page.

Taxonomic Remarks
The position of the species as a synonym of Notoscopelus elongatus (Costa, 1844) is apprently a mistake. Fixation of the issue in progress.

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00427 (0.00195 - 0.00931), 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   ±0.1 se; based on diet studies.
Generation time 5.5 ( 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 (K=0.2).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (39 of 100). 🛈
