Etheostoma


Etheostoma is a genus of small freshwater fish in the family Percidae, and within the sub-family Etheostomatinae, native to North America. Most are restricted to the United States, but species are also found in Canada and Mexico. They are commonly known as darters, although the term "darter" is shared by several other genera. Many can produce alarm pheromones that serve to warn nearby fish in case of an attack.

Species

The 146 recognized species in this genus are arranged into 18 subgenera. Two former subgenera, Allohistium and Nothonotus have been promoted to full genera.
