Neoscopelus macrolepidotus, also known as a large-scaled lantern fish, is a species of small mesopelagic or bathypelagic fish of the family Neoscopelidae, which contains six species total along three genera. The family Neoscopelidae is one of the two families of the order Myctophiformes. Neoscopelidae can be classified by the presence of an adipose fin. The presence of photophores, or light-producing organs, further classify the species into the genus Neoscopelus. N. macrolepidotus tends to be mesopelagic until the individuals become large adults, which is when they settle down to the bathypelagic zone.

The species Neoscopelus macrolepidotus is described as having a dark grey ventral surface, a greyish-silver head, pinkish-red fins, and rows of photophores along the ventral portion of the body and along the sides of the tongue. These photophores produce and emit light in the process of bioluminescence. The species generally does not exceed 25 cm in length and is found exclusively in marine environments, along various parts of the Atlantic, Indian and Pacific Oceans on continental shelves.
