A small fish of the family Atherinidae, including species of silversides and sand eels found in marine and freshwater environments.
From French athérine, from Greek atherina, possibly deriving from a- (without) + therme (hot), or referring to the transparent or glassy appearance of these fish.
Atherines are one of those fish that barely anyone knows by name but that you might have caught as a kid—they're the tiny silver fish in shallow water, and they're actually found on nearly every coast on Earth.
