description Pearlside Overview
Pearlsides are small marine fish belonging to the genus Maurolicus, which is part of the family Sternoptychidae (hatchetfishes). These fish are mesopelagic, meaning they inhabit the middle depths of the ocean, typically performing daily vertical migrations. They are characterized by their silvery, reflective scales and rows of photophores (light-producing organs) on their undersides, which they use for counterillumination—a form of camouflage that helps them avoid detection from below by matching the faint light filtering down from the surface. Pearlsides are found in oceans worldwide and often form large schools.
