Description

The lesser silverside is a small schooling fish of the New World silverside family (Atherinopsidae) from the eastern Pacific. The species grows to about 8 cm and has a slender, silvery body with a shining silver lateral stripe. It forms small schools in shallow bays and near coastal reefs. As an omnivore it feeds on small zooplankton and small invertebrates near the surface. As an abundant prey fish it is important to larger predatory fishes and seabirds. Reproduction is oviparous. Owing to its small size the species has little direct fishery value and is harmless to humans.
