Diaphus bertelseni, or Bertelsen's lanternfish, is a species of oceanodromous lanternfish, first described in 1966 by Basil Nafpaktitis.[2][3]
The species epithet, bertelseni, honours the Danish ichthyologist, Erik Bertelsen.[3]
Diaphus bertelseni lives in the Eastern Atlantic, Western Atlantic, Southwest Pacific, and Eastern Pacific at depths up to 300 meters.[2] They are mostly at 200 to 300 meters deep during the day, and 60 to 175 meters deep at night.[4]
Diaphus bertelseni grows to a length of 9.1 cm, and can have up to 15 dorsal fins, 15 anal fins, 8 pelvic fins, 18 gill rakers, and 35 lateral lines.[2] Their coloring is dark with paler photophores.[4]
