The Bluemask Darter (Etheostoma akatulo) is a small, colorful freshwater fish endemic to the upper Caney Fork River system in Tennessee. This species is named for the striking blue coloration displayed by males during the breeding season, which contrasts with their otherwise mottled brown and green bodies. Bluemask Darters rely on clean, well-oxygenated streams with gravel and sand substrates, where they forage for small invertebrates. Spawning occurs in gravelly areas where eggs are covered to protect them from predators and currents. The species' restricted range, specialized habitat requirements, and vulnerability to habitat disturbances make it a critical focus for conservation efforts.
