Entosphenus is a genus of lampreys.
Six species in this genus are recognized: [1]
Petromyzontidae are a family of lampreys native to the Northern Hemisphere, comprising the vast majority of living lampreys. Petromyzontids have the highest number of chromosomes (164–174) among vertebrates.
The Pacific lamprey is an anadromous parasitic lamprey from the Pacific Coast of North America and Asia in an area called the Pacific Rim. It is a member of the Petromyzontidae family. The Pacific lamprey is also known as the three-tooth lamprey and tridentate lamprey.
The European river lamprey, also known as the river lamprey or lampern, is a species of freshwater lamprey.
The mountain brook lamprey or Allegheny brook lamprey is a lamprey found in parts of the Mississippi River basin, New York, Pennsylvania, Ohio, and in the Cumberland River and Tennessee River. This fish is jawless with a small sucker mouth and a long, eel-like body. It is fairly small, only growing to about 8 inches (20 cm) in length.
Mordacia is a genus of lamprey, the sole genus of the family Mordaciidae, also known as the southern topeyed lampreys.
The northern brook lamprey is a freshwater fish in the family Petromyzontidae. It is closely related to the silver lamprey and may represent an ecotype of a single species with I. unicuspis.
Eudontomyzon is a genus of lamprey in the family Petromyzontidae. Most species are found in Eastern Europe.
Eudontomyzon vladykovi, or Vladykov's lamprey, is a species of lamprey in the family Petromyzontidae. It is found in Austria, Germany, The Czech Republic, Bulgaria, Romania, Serbia, and Montenegro.
The Kern brook lamprey is a species of lamprey in the Petromyzontidae family endemic to the United States. It is found on the east side of San Joaquin Valley, in lower Merced, Kaweah, Kings, and San Joaquin rivers in California. It can grow to up to around 14 centimeters, and is characterized by its grayish brown and white coloring, and black spots on its fins.
Lampetra is a genus of lampreys in the family Petromyzontidae.
The lake lamprey, Entosphenus macrostomus, also known as the Vancouver lamprey or Cowichan lamprey, a recent derivative of the Pacific lamprey, is a species of freshwater lamprey endemic to two North American lakes: Lake Cowichan and Mesachie Lake in Vancouver Island, Canada. The lamprey was originally called the Vancouver Island lamprey, until an error in filing shortened it to the Vancouver lamprey. The alternate common name of "Cowichan lamprey" was coined and promoted by the species' describer, Dr. Dick Beamish, who originally identified the species in the 1980s.
The Miller Lake lamprey is a species of lamprey in the Petromyzontidae family endemic to the United States. Its natural habitat is the Miller Lake drainage in the state of Oregon.
Lethenteron is a genus of lamprey in the family Petromyzontidae.
Lampreys are a group of jawless fish comprising the order Petromyzontiformes. The adult lamprey is characterized by a toothed, funnel-like sucking mouth. The common name "lamprey" is probably derived from Latin lampetra, which may mean "stone licker", though the etymology is uncertain. Lamprey is sometimes seen for the plural form.
Caspiomyzon is a genus of lamprey in the family Petromyzontidae. They are native to Eastern Europe and parts of Western and Central Asia. Two of the three species in the genus are endemic to Greece.
Ichthyomyzon is a genus of lampreys in the family Petromyzontidae, native to North America.
Tetrapleurodon is a genus of lampreys that are endemic to the Lerma–Chapala basin in west–central Mexico. Both species are threatened.
Oregon & Northern California Coastal is a freshwater ecoregion in western North America. It includes the coastal rivers of Oregon and Northern California, from the Columbia River mouth in northwestern Oregon to northern Monterey Bay in Central California. It includes the Umpqua, Rogue, Smith River, Klamath, Mad, Eel, and lower Russian rivers, and many smaller coastal rivers and streams, including those on the coast side of the Marin and San Francisco peninsulas.
