Classification / Names Noms communs | Synonymes | Catalog of Fishes(Genre, Espèce) | ITIS | CoL | WoRMS | Cloffa

> Myctophiformes (Lanternfishes) > Myctophidae (Lanternfishes) > Notolychninae
Etymology: Notolychnus: Greek, noton = back + Greek, lychnos, -ou = torch (Ref. 45335).
Eponymy: Both these species are named after the research vessel ‘Valdivia’ and the Valdivia expedition (1898–1899), Germany’s first expedition to explore deep seas. The holotypes were collected during the expedition. (Ref. 128868), visit book page.

Biologie     Glossaire (ex. epibenthic)

High-oceanic, epipelagic and mesopelagic (Ref. 4479). Found between 375-700 m during the day and between 25-350 m at night (Ref. 4066). Size stratification with depth during the day only (Ref. 4775). Juveniles migratory; adults migratory, partially migratory or non-migratory (Ref. 4775). Feed on copepods, conchoecid ostracods and euphausiids (Ref. 4775). Oviparous, with planktonic eggs and larvae (Ref. 31442). Also Ref. 58302.
