The Blue Ridge sculpin (Cottus caeruleomentum) is a species of sculpin in the family Cottidae. It is native to the eastern United States, where it can be found in a number of river systems that drain into the Atlantic. [2] [3]
This fish is variable in morphology. [4] It is up to about 6.3 centimeters long. [2] In general, the species has dark saddle marks and an incomplete lateral line. There are small spines on the preoperculum and small prickles in the postpectoral area. [4] The breeding male, at least in some regions, has blue to blue-green coloration on the chin, the mouth, the bases of some of the fins, and the membrane connecting the bones around the gills. [5] The fish is very similar to its close relative, Cottus bairdi , particularly the subspecies C. b. bairdi. The latter has notches in the band marking the base of the tail; C. caeruleomentum lacks the notches on one or both sides. [4] C. bairdi lacks the blue breeding coloration; its chin is blackish. The two fish occur together and are known to hybridize. [5]
This fish is native to the states of Delaware, Maryland, North Carolina, Pennsylvania, Virginia, and West Virginia. It can be found in the Elk, Susquehanna, Bush, Patapsco, Patuxent, Potomac, Nanticoke, James, and Roanoke river drainages. The species is common in upland habitat, and less common in lowlands. It lives in creeks, springs, and riffles. In coastal areas it is only found in cold streams. [3]
The diet is made up of invertebrates. [3]
The parasite load of this species has been investigated. The nematode Rhabdochona cotti lives in its intestine. [6] Another nematode was found there and subsequently described as a new species named Freitascapillaria laticauda . It can be over a centimeter long. [7]
The spoonhead sculpin is a North American freshwater fish of the family Cottidae. This species is not as common as its cousin species the mottled sculpin.
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 sculpin family Cottidae. 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 mottled sculpin is a freshwater sculpin found widely although unevenly throughout North America.
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, and common bullhead.
Cottus microstomus is a species of sculpin, a European freshwater fish in the family Cottidae. It 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.
Cottus asper is a species of fish in the sculpin family known by the common name prickly sculpin. 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.
Cottus rondeleti is a species of freshwater cottid fish that is only found in the coastal Hérault drainage of Southern France. The total known distribution comprises three distinct short stretches of stream, and the species considered critically endangered because of threat of drought that is promoted by water extraction and potentially by climate change.
Cucullanus is a genus of parasitic nematodes. The genus includes more than 100 species.
The shorthead sculpin is a species of fish in the family Cottidae. It is found in the United States and Canada, inhabiting the Columbia River drainage in Washington, Oregon, Idaho, Montana, and British Columbia. It is also found in the Puget Sound drainage in Washington. It reaches a maximum length of 15.0 cm. It prefers rocky riffles of headwaters and creeks.
The 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 Ozark sculpin is a species of fish in the family Cottidae. It is found in the United States and Canada, 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 fish in the family Cottidae. It is found in the United States, inhabiting the Klamath River drainage in California and Oregon, and the Pit River system from Fall River to Hat Creek, California. It reaches a maximum length of 9.0 cm. It prefers soft-bottomed runs of clear, cold creeks and small to medium rivers.
The margined sculpin is a species of fish in the family Cottidae. It is found in the United States, inhabiting the Columbia River drainage from the Walla Walla River system, Washington, to the Umatilla River system in Oregon. It reaches a maximum length of 13.0 cm. It prefers rubble and gravel riffles.
The reticulate sculpin is a species of fish in the family Cottidae. 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. It's 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 torrent sculpin is a species of fish in the family Cottidae. 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. It reaches a maximum length of 15.5 cm. It prefers swift waters of small to large rivers with stable gravel or rubble bottoms, and rocky lake shores.

It is found in the United States in the Tallapoosa River drainage above the Fall Line in east central Alabama and west-central Georgia. It reaches a maximum length of 7.7 cm. It prefers rocky shoals and riffles of small upland streams.
