Diaphus rafinesquii: The White-spotted Lantern Fish

The white-spotted lantern fish (Diaphus rafinesquii) is a deep-sea species found in various parts of the world, including the Atlantic Ocean, Mediterranean Sea, Gulf of Mexico, and Caribbean Sea. This fish has been widely accepted as one of its common names by the Committee on Names of Fish.

In terms of distribution, Diaphus rafinesquii exhibits oceanodromous behavior, meaning it migrates across entire oceans in search of food and suitable habitats. The species is primarily found at depths ranging from 40 to 2,173 meters (131 to 7,129 feet), with adults typically residing between 300 to 600 meters (980 to 1,970 feet) below the surface during the day, while juveniles are more commonly spotted at shallower depths of around 40 to 200 meters (130 to 660 feet).

The lantern fish's behavior is characterized by its nocturnal nature, with adults occupying deeper waters. Males tend to be slightly larger than females. In terms of size, Diaphus rafinesquii can grow up to 9 centimeters in length.

Contrary to some sources suggesting a connection to Madagascar or Brazil, the majority of evidence points towards the white-spotted lantern fish being found primarily in tropical and temperate regions with seas, bays, and streams. The species is not considered endangered, according to current conservation status assessments.
