Banded sculpin
The banded sculpin (''Cottus carolinae'') is a freshwater fish dwelling mostly in small to moderate sized streams in areas of swift current. Young and juvenile ''C. carolinae'' can mainly be found in pools, riffles, and other shallow habitats while adults tend to prefer deeper waters. Mating and nesting for the sculpin is in spring, with males carefully guarding the eggs until they hatch.〔Cathy Koczaja, Laura McCall, Elizabeth Fitch, Brad Glorioso, Chad Hanna, Juliana Kyzar, Matthew Niemiller, Jeremy Spiess, Amy Tolley, Richie Wyckoff, and Dennis Mullen. 2005. Size-Specific Habitat Segregation and Intraspecific Interactions in Banded Sculpin (''Cottus carolinae''). Southeastern Naturalist 10: 207-218〕
''C. carolinae'' primarily eats insects and insect larvae such as Ephemeropterans, or the may fly, with little predation on other fish and crustaceans. Their large mouths enable them to eat prey nearly as large as themselves, including other sculpin.〔Renn Tumlison and George R. Cline. 2002. Food Habits of the Banded Sculpin (''Cottus carolinae'') in Oklahoma With Reference to Predation on the Oklahoma Salamander (''Eurycea tynerensis''). Proceedings of the Oklahoma Academy of Science 82:111-113〕 ''C. carolinae'' itself is preyed upon by larger fish, most significantly Trout. To prevent predation, the color and pattern of the sculpin tends to match its environment. Most ''Cottus carolinae'' are mottled brown with dark vertical banding and usually reach about three inches in length. They have a broad head which rather quickly narrows into a slim body, giving them the appearance of a tadpole reaching adulthood.
