Holston Sculpin (Cottus sp. cf. bairdii)

Description: 

The Holston Sculpin is an undescribed species restricted to the upper Holston River drainage in Virginia and Tennessee. They are found in a variety of habitats but thrive in cool water and swift currents. Like all sculpins, they are ambush predators that use their cryptic coloration to hide on stream bottoms and eat anything that fits into their extremely large mouth.
