Description

The hardhead silverside is a slender, semi-transparent fish of the family Atherinidae reaching about 10 cm. A conspicuous, shiny silver band runs along the side; the back is greenish and the body has two small, separate dorsal fins. The species forms dense, glittering schools in shallow coastal water over seagrass, coral and mangroves in the western Atlantic and the Caribbean. It eats zooplankton, especially copepods and larvae. Through its enormous numbers it is an indispensable prey fish for predators, seabirds and larger reef fish; the glittering schools are a familiar sight on the shallow reef.
