Maurolicus is an oceanic ray-finned fish genus which belongs in the family Sternoptychidae. They are commonly known as pearlsides, but the brilliant pearlside is the related Argyripnus iridescens. Occasionally, "bristle-mouth fishes" is used as a common name, but that usually refers to the genus Argyripnus or the family Gonostomatidae.


There are currently 15 recognized species in this genus:[1]

Fossils of pearlsides are known from the Miocene.[2]
