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.
