Etheostoma is a diverse genus of small freshwater fish in the family Percidae. It contains nearly 140 member species. Most are native to North America. 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.
