Etheostoma is a diverse genus of small freshwater fish in the family Percidae. It contains more than 150 species. Most are restricted to the United States, but there are also species in Canada and Mexico. They are commonly known as darters although the term "darter" is shared by several other genera. Many can produce Schreckstoff substances[2] that serve to warn nearby fish in case of an attack.
