The slimy sculpin is a freshwater species of fish belonging to the family Cottidae, which is the largest sculpin family. They usually inhabit cold rocky streams or lakes across North America, ranging from the Great Lakes, southeast Minnesota, northeast Iowa, southwest Wisconsin and northeast Canada. Slimy sculpins have also been found roaming the cold streams of eastern Siberia. They are commonly confused with their closely related relatives, Mottled sculpin, and with tubenose gobies who are both freshwater fishes as well. The slimy sculpin is a nocturnal fish that usually spends most of its time on the stream bottom and seeks shelter under rocks and logs, especially during spawning season. When it swims, it sometimes appears to be "hopping" along the bottom because of its inefficient ability to swim. This is partly due to the absence of a swim bladder, which normally gives buoyancy to a fish.
Cottus is a genus of the mainly freshwater ray-finned fishes belonging to the family Cottidae, the typical sculpins. They are often referred to as the "freshwater sculpins", as they are the principal genus of sculpins to be found in fresh water. They are native to the Palearctic and Nearctic.

It inhabits spring systems in the Thousand Springs formation near Hagerman, south-central Idaho. It reaches a maximum length of 9.0 cm. The specific name honors Charles Wilson Greene who was an instructor in physiology at Stanford University and was on the expedition on which the type was collected from the Thousand Springs on the Snake River, near mouth of Salmon Falls River in Gooding County, Idaho.

The banded sculpin 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. C. carolinae primarily eats insects and insect larvae, but their large mouths enable them to eat prey nearly as large as themselves, including other sculpin. To prevent predation, including by other fish, 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.
The prickly sculpin is a species of ray-finned fish belonging to the family Cottidae, the typical sculpins. It is native to the river drainages of the Pacific Slope of North America from Seward, Alaska south to the Ventura River of Southern California. It extends east of the Continental Divide in the Peace River of British Columbia. It has also been introduced to several reservoirs in Southern California.
The Potomac sculpin is a freshwater species of sculpin that lives in West Virginia, Maryland, Virginia and Pennsylvania.
The black sculpin is a species of freshawater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is endemic to the United States. Its range includes the extreme upper Clinch and Holston River systems in western Virginia and just into northeastern Tennessee. It reaches a maximum length of 8 cm (3.1 in).
The Paiute sculpin is a species of fish in the family Cottidae. It is found in the United States, inhabiting the Columbia River drainage from Idaho, western Wyoming, and northeastern Nevada to western Washington and Oregon, and endorheic basins including Lake Tahoe in Nevada and California. It reaches a maximum length of 13.0 cm. It prefers rubble and gravel riffles of cold creeks and small to medium rivers. It is also found in rocky shores of lakes. Paiute sculpin are benthic organisms, residing at the bottom of their environments.
The inland riffle sculpin is a species of fish in the family Cottidae. It is found in the United States, inhabiting the lower Columbia River drainage in Washington, to Morro Bay in California. It is also found in the Puget Sound drainage in Washington. It reaches a maximum length of 11.0 cm. It prefers rocky riffles of headwaters and creeks.
The knobfin sculpin is a species of fish in the family Cottidae. It is found in the United States, inhabiting the Current, Eleven Point, Spring and White river systems in the Ozark Highlands of Arkansas and Missouri. An invasive non-native introduced population is present in the Pomperaug River drainage in Connecticut. It reaches a maximum length of 9.0 cm. It prefers rocky riffles of headwaters and creeks.
The fourspine sculpin is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is endemic to Japan. It reaches a maximum length of 30.0 cm (11.8 in).
The reticulate sculpin is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found in the United States, inhabiting Pacific Slope drainages from the Snohomish River and Puget Sound in Washington to the Rogue River system in Oregon and California. It reaches a maximum length of 10.0 cm. This sculpin occurs in a variety of habitats, but mainly occurs in the slower sections of coastal headwaters, creeks, and small rivers. It prefers faster water with rubble or gravel substrate, but occurs in pools and along stream edges when other sculpin species are present. Often it occurs in clear cold water in forested areas. Its ideal habitat is cold creeks in old-growth forest, with plenty of riffles and runs. This species is tolerant of variable water temperatures and salinities. Where other sculpin species are common, spawning occurs in slow-flowing areas; where other sculpin species are rare or absent, spawning usually occurs in riffles.
The Pit sculpin is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found in the United States, inhabiting the Pit and upper Sacramento River systems in Oregon and California. It reaches a maximum length of 13.0 cm. It prefers rubble and gravel riffles.
Cottus volki is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is endemic to Russia where it is found along the continental coasts of the Sea of Japan but not on the coasts of Peter the Great Bay. It reaches a maximum length of 13 cm (5.1 in). It was previously considered a subspecies of the alpine bullhead. and this species was first formally described in 1933 by the Russian ichthyologist Anatoly Yakovlevich Taranetz as Cottus poecilopus volki with its type locality given as the Suchan River to Takema River on western coast of the Sea of Japan in Primorye. Taranetz did not identify the person honoured in the specific name but it is thought most likely to be his friend Alexander Maksimovich Volk, like Taranetz, Volk was killed in action during World War 2.
