The Soft Lanternfish, Diaphus mollis, has been found to depths of 600 meters. Myctophid fishes comprise an important part of the "deep scattering layer" or DSL. The DSL is a community of deep water wildlife that migrates, every day, to shallower waters to feed on plankton at night. They return to the depths by day. It is the largest migration of wildlife on the planet, and it happens every 24 hrs. Lanternfishes are often deciphered by the number of and arrangement of the photophores on their heads and bodies. This individual was trawled up in the Gulf of Mexico, 2015.
