The brook lamprey, also known as the European brook lamprey and the western brook lamprey is a small European lamprey species that exclusively inhabits freshwater environments. The species is related to, but distinct from, the North American western brook lamprey.
The Arctic lamprey, also known as the Japanese river lamprey or Japanese lampern, is a species of lamprey, a jawless fish in the order Petromyzontiformes. It inhabits coastal freshwater habitat types in the Arctic. Some populations are anadromous, spending part of their lives in the ocean. It is the most common and widespread lamprey in the Arctic region.
Mordacia praecox, the Australian brook lamprey or nonparasitic lamprey, is a freshwater species of southern topeyed lamprey that occurs in south-eastern Australia. It has a thin eel-like body around 12 to 15 cm long, with two low dorsal fins on the back half. The skin is dark blue above and grey below. Its eyes are small, and located on the top of its head. Unlike M. mordax, M. praecox has eyes that appear to have the potential for dichromatic vision despite being similarly adapted for low-light environments.
The European river lamprey, also known as the river lamprey or lampern, is a species of freshwater lamprey.
The western brook lamprey is a small (<18 cm), widely distributed, non-parasitic species of jawless fish endemic to the freshwater coastal waterways of the Western United States and Canada. Its range extends from the North American Pacific coast from Taku River, southern Alaska, Queen Charlotte Islands, to central California, including Vancouver Island, with major inland distributions in the Columbia and Sacramento-San Joaquin watersheds.
The chestnut lamprey is a species of lamprey.
Lethenteron appendix, the American brook lamprey, is a common non-parasitic lamprey in North America. In adults their disc-like mouths contain poorly developed teeth, useless for attaching to a host.
The southern brook lamprey is a lamprey found in the Southern United States including Arkansas, Louisiana, Mississippi, Alabama, and Georgia. It is a jawless fish with a sucking mouth on one end of it. It can appear to be a small eel, since it is rarely longer than one foot in length.
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 danfordi, the Carpathian brook lamprey or Danube lamprey, is a species of lamprey in the family Petromyzontidae. It is found in Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Hungary, Moldova, Romania, Serbia, Montenegro, Slovakia, and Ukraine. Unlike other brook lampreys, this fish is parasitic.
The Greek lamprey is a species of jawless fish in the Petromyzontidae family. It is endemic to Greece. Its natural habitats are rivers and freshwater springs. It is threatened by habitat loss. Originally considered a species of the genus Eudontomyzon, later phylogenetic analyses suggested that a placement within Caspiomyzon was more likely. It is the most endangered species of lamprey, living only in the Strymon and Louros river basins.
The Ukrainian brook lamprey is a species of lamprey in the Petromyzontidae family. It is found in brackish and freshwater areas in Austria, Belarus, Bulgaria, the Czech Republic, Georgia, Hungary, Moldova, North Macedonia, Poland, Romania, Russia, Serbia, Montenegro, Slovakia, Turkey, and Ukraine. It invaded the basin of the Volga River in 2001.
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 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.
Mordacia lapicida, also known as the Chilean lamprey, is a species of southern topeyed lamprey endemic to southern Chile, where it can be found in riverine and marine habitats. This species is anadromous. This parasitic lamprey can reach a length of 54 centimetres (21 in) SL. Ammocoetes and adults of this species are found in rivers, and occur in fine sand along river banks. The life cycle of a Mordacia lapicida is divided into three life stages: freshwater rearing, an ocean parasite and an adult spawning stage. Once in the adult stage, individuals migrate into marine waters where they attack and attach themselves to marine fishes. For this species, metamorphosis occurs during August and March.
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.
The least brook lamprey is a common, non-parasitic lamprey distributed in the Mississippi River watershed, and a limited range along the Atlantic coast.
Lampetra ayresii is a species of lamprey in the family Petromyzontidae. It is also called the river lamprey or western river lamprey. It is found in the eastern Pacific, specifically from Tee Harbor, Juneau in Alaska to the Sacramento–San Joaquin drainage in California, USA. It can survive in both marine surface waters and freshwater lakes, rivers, and creeks. In freshwater, it is found typically in the lower portions of large river systems. It is a predatory fish and feeds on fishes in the size range of 10–30 cm. It feeds by attaching to prey using its round, sucker-like mouth. Adult western river lampreys typically grow to about 21 cm (8.3 in) total length (TL), but can reach 31 cm (12 in) TL.
