The corrugated darter (Etheostoma basilare) is a species of darter endemic to the eastern United states only known from the Caney Fork, Tennessee, where it has been shown to have as many as five subgroups. They are active hunters which prey on insects, fry, and possibly young snails. Multiple species and subspecies of these darters can coexist where substrate is varied, so this must be carefully preserved to accommodate many similar species. With the warming of spring, E. basilare enters its breeding cycle and males develop their dimorphic coloration. Like most darters, it hugs the stream bed, using its body shape and fin posture to maintain its position. This lifestyle which is so dependent upon the benthic architecture of the stream is highly impacted by disturbance, which can be the res
