The oceanic lightfish is a very small elongate deepwater species with large eyes and head. It has only one [[dorsal fin]], and there are a distinctive series of short fleshy appendages around each side of the upper jaw. |

It is the main prey of tuna during the tuna fishing season (late autumn and winter) in the equatorial Atlantic. Its own diet is varied and is dependent on its location. In equatorial locations it has been found to behave as a mesopelagic fish and as an opportunistic mesozooplankton feeder, whilst further north in oligotrophic typical tropical structures it was found to behave as an epipelagic fish, feeding on the dominant small prey during the daytime.<ref>{{cite journal | url=https://www.researchgate.net/publication/225486459 | doi=10.1007/s00227-008-1067-z | title=Feeding behavior of adult Vinciguerria nimbaria (Phosichthyidae), in the tropical Atlantic (0°–4°N, 15°W) | year=2008 | last1=Champalbert | first1=Gisèle Amélie | last2=Kouamé | first2=Basile | last3=Pagano | first3=Marc | last4=Marchal | first4=Emile | journal=Marine Biology | volume=156 | pages=79–95 | s2cid=84977688 }}</ref> |

Oceanic lightfish are abundant in the deep oceans of the world. They undertake daily vertical migrations, rising to the suface during the night to feed upon small [[copepod]]s. |

The oceanic lightfish (Vinciguerria nimbaria) a lightfish of the genus Vinciguerria, is found in all deep tropical and subtropical oceans and seas, from depths of 20 to 5,000 m. Its length is between 2 and 5 cm. It is the main prey of tuna during the tuna fishing season (late autumn and winter) in the equatorial Atlantic. Its own diet is varied and is dependent on its location. In equatorial locations it has been found to behave as a mesopelagic fish and as an opportunistic mesozooplankton feeder, whilst further north in oligotrophic typical tropical structures it was found to behave as an epipelagic fish, feeding on the dominant small prey during the daytime.[1]
