Bluebreast darter
The bluebreast darter (''Etheostoma camurum'') is a species of darter endemic to the eastern United states from New York and Illinois to Tennessee and North Carolina.
==Introduction==
The bluebreast darter is small in size, rarely reaching longer than three inches. The snout is a blunt, more rounded than other darters, and its gill covers do not bridge the breast. It is a colorful fish, predominantly olive green with a broad, lighter band that runs adjacent to the dark fringe of the second dorsal and anal fins, reaching the base of the caudal fin. During breeding, though, males tend to be very colorful, usually with orange-tinted dorsal fins, dark red spots along the sides, and the descriptive bright blue breast from which it gets its name.〔Felbaum, M., et al. 1995. Endangered and Threatened Species of Pennsylvania. ''Wild Resource Conservation Fund.''〕 The species is commonly found in clean-flowing, medium to large rivers with high benthic current velocity and an abundance of sedimentary gravel. Currently, ''E. camurum'' is listed as imperiled or higher in seven eastern US states.〔
