Cottus koshewnikowi, Koshewnikow's sculpin, is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It inhabits the upper Volga drainage in Russia and drainages of the northern and eastern Baltic Sea from Estonia eastward and northward to Finland and northern Sweden. In coastal waters of the Northern Baltic Sea it forms hybrid populations with the more western bullhead species Cottus gobio (sensu stricto).
It reaches a maximum length of 10 cm (3.9 in). [2] It prefers medium-sized rivers to small streams, and lake shores.
The spoonhead sculpin is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is widespread in northeastern North America.
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.

The European bullhead is a freshwater fish that is widely distributed in Europe, mainly in rivers. It is a member of the family Cottidae, a type of sculpin. It is also known as the miller's thumb, freshwater sculpin, common bullhead, and cob.
The fourhorn sculpin is a species of ray-finned fish belonging to the family Cottidae, the typical sculpins. This species has a Holarctic distribution and can be found in marine, brackish and fresh waters.
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.
Cottus microstomus is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found in Eastern Europe and is widespread in the Dniester drainage, Odra and Vistula drainages, most likely extending further east to the Gulf of Finland. It is part of the wider European Cottus gobio complex, and possibly makes hybrid zones with Cottus gobio and Cottus koshewnikowi. It is a demersal fish, up to 10.1 cm long.
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 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 shorthead sculpin is a species of fish in the family Cottidae. Shorthead Sculpins are bottom-dwelling small fish, typically sizing around 13 to 15 cm long. They have large heads and fanlike pectoral fins. They have 7-9 dorsal spines, 15-19 dorsal soft rays, and 10-14 anal soft rays. Narrow caudal peduncle. Palatine teeth and coloration being dark brown and yellow.
Cottus duranii, the Dordogne sculpin or chabot d'Auvergne, is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found in France. It inhabits the Loire and Dordogne river drainages. It reaches a maximum length of 10.0 cm. It prefers streams with clear, cool, moderate to swift water and stone substrate. This species was described as a separate species from the European bullhead in 2005 by Jörg Freyhof, Maurice Kottelat and Arne W. Nolte. The specific name durani means "of Duranius", the Latin name of the River Dordogne.
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.

The Ozark sculpin is a species of ray-finned fish belonging to the family Cottidae, the typical sculpins. It is endemic to Missouri, United States. Inhabiting the Osage, Gasconade, and Black river drainages in Missouri. It reaches a maximum length of 14.0 cm. It prefers rocky riffles of headwaters and creeks.
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.
The torrent sculpin is a species of ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found in the United States and Canada, inhabiting upper Fraser River drainage in British Columbia to the Nehalem River in Oregon (including the Columbia River drainage of British Columbia, Washington, Idaho, Montana and Oregon.

Cottus cyclophthalmus is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is found in northeastern Europe, in the Neman River and Venta River drainages in the basin of the Baltic Sea. This species is similar to the European bullhead but is distinguished by uts round, protruding and tubular eyes set close to the front of head; papillae in the skin on the top and sides of the head, a scale-less body without any bony prickles and a complete sensory canal on the flanks which has 32–36 pores. It is classified within the subgenus Cottus and the specific name cyclophthalmus is a compound of cyclos, meaning "round", and ophthalmus, which mean "eye", an allusion to the round, tubular eyes.
The Coastal Riffle Sculpin is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is endemic to the Coast Range Mountains of California, where it is found in streams draining to the west and southwest. This taxon was considered to be conspecific with the inland riffle sculpin until research published in 2020 by Peter B. Moyle and Matthew A. Campbell showed that it was a separate valid species which was split into two subspecies. One, C.o. pomo, found in the northern Russian River and north San Francisco Bay drainage; and the other, C.o. ohlone, in the southern Santa Clara Valley. The specific name honors the Ohlone people, a Native American group which lived around southern San Francisco Bay and the Santa Clara Valley. The Ohlone name refers to a group of over 50 people who interacted in these areas. It is not listed with a conservation status under the Endangered Species Act.
