Teleostei (teleosts) > Myctophiformes (Lanternfishes) > Myctophidae (Lanternfishes) > Myctophinae
Etymology: Myctophum: Greek, mykter, -eros = nose + Greek, ophis = serpent (Ref. 45335); ovcharovi: Named in honor of Oleg Petrovich Ovcharov (InBYuM, Ukrainian Academy of Sciences), myctophid specialist who first noted that M. asperum does not migrate to the surface during its diurnal vertical migrations (Ref. 11324).
Eponymy: Oleg Petrovich Ovcharov of the Ukrainian Academy of Sciences made particular studies of how fish move through water and their growth patterns. [...] (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 25.4 - 26.8, mean 25.8 °C (based on 8 cells).

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

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

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).
