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.

Paiute sculpin are benthic organisms, residing at the bottom of their environments.
The shorthead sculpin is a species of fish in the family Cottidae. Shorthead sculpins are small, bottom-dwelling fish, typically measuring around 13 to 15 cm in length. They have large heads, fanlike pectoral fins, and a narrow caudal peduncle. Their physical characteristics include 7–9 dorsal spines, 15–19 dorsal soft rays, 10–14 anal soft rays, and palatine teeth. Their coloration is a mix of dark brown and yellow.
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 Columbia sculpin is a species of fish in the family Cottidae. It is found in the United States and Canada, inhabiting the Columbia River drainage and Harney Basin in Oregon, British Columbia, Idaho, Washington, and Nevada. It reaches a maximum length of 11.2 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 marbled sculpin is a species of sculpin found in the Klamath and Pit River drainages in northern California and southern Oregon. Three subspecies have been identified: the upper Klamath marbled sculpin, which occurs in the Klamath River watershed above Klamath Falls; the lower Klamath marbled sculpin, which occurs in the Klamath River watershed downstream of Iron Gate Dam; and the bigeye marbled sculpin, which inhabits the Pit River Watershed. However, genetic analysis performed in 2012 indicated minimal difference between individuals from each of these three regions.
Cottus nozawae is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found in southern Sakhalin Island in Russia, Hokkaido and northern Honshu in Japan and in the Korean Peninsula. It reaches a maximum length of 6.9 cm. This species was first formally described in 1911 by the American ichthyologist John Otterbein Snyder with its type locality given as the Ishikari River at Sapporo on Hokkaido. This species is sometimes placed in the subgenus Cephalocottus. The specific name honours zoologist Shunjiro Nozawa, Director of the Fisheries Bureau on Hokkaido.
Cottus perifretum, the bullhead or miller's thumb, is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found on both sides of the English Channel, native to Great Britain. It also inhabits Atlantic drainages from the Garonne River to the Scheldt in France and Belgium, and the Moselle and Sieg in Germany. It is considered invasive in the Rhine drainage in Germany and the Netherlands. This invasive population in the Rhine is an intermediate between this species and Cottus rhenanus. Although this species is native to England and Wales it is considered to be a non-native invasive species in Scotland.
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.
