Darter (fish)

The fish popularly known as darters are small, perch-like fish found in freshwater streams in North America. They are members of the family Percidae and include members of the Ammocrypta, Crystallaria, Etheostoma and Percina genera.

Some darters are widespread throughout North America, most notably in New Jersey, Tennessee, and Kentucky, but others are restricted to single streams, leaving them vulnerable to extinction.

Percidae

The Percidae are a family of perciform fish found in fresh and brackish waters of the Northern Hemisphere. The family contains about 200 species in ten genera. The darters, perches, and their relatives are in this family: well-known species include the walleye, ruffe, and three species of perch.

This family is characterized by a greater or less degree of armour about the head, caused by the presence of teeth or spines on the cheeks, and opercles (gil-covers) or their edges, and by two narrow bands of numerous close-set teeth on the sides (palatines), and a heart-shaped plate of the same in front (on the vomer) of the roof of the large mouth within. The shape of these fishes is usually oblong, compressed, neither very deep nor much elongated, their scales are generally harsh and rough to the feel, or ciliate, and their colors are brilliant (red, brown, orange and yellow are the most predominant tints).

Species

FishBase lists 204 species in ten genera:[1]
