The Arctic lamprey (Lethenteron camtschaticum), also known as the Japanese river lamprey or Japanese lampern (Petromyzon japonicus Martens 1868, Lampetra fluviatilis japonica (Martens 1868), Lampetra japonica (Martens 1868), Lethenteron japonicum (Martens 1868) ), is a species of lamprey, a jawless fish in the order Petromyzontiformes. It inhabits coastal freshwater habitat types in the Arctic. [4] Some populations are anadromous, spending part of their lives in the ocean. It is the most common and widespread lamprey in the Arctic region. [5]

Description

This lamprey is usually about 13 to 32 centimetres (5.1 to 12.6 in) long, but specimens have been known to reach 63 centimetres (25 in) and 200 grams (7.1 oz) in weight. Non-anadromous individuals are rarely over 18 centimetres (7.1 in) long. [4] It is brown, gray, or olive in color with a paler belly. There are two dorsal fins located near the tail, the posterior one larger than the anterior. Males are larger than females. The caudal fin has two lobes, the lower longer than the upper. It is continuous with the dorsal and anal fins. The anal fin of the male takes the form of a small ridge. [4]

Distribution and habitat

The Arctic lamprey is a circumpolar species. Its range extends from Lapland eastward to Kamchatka and southward to Japan and Korea. It also inhabits the Arctic and Pacific drainages of Alaska and northwestern Canada. Arctic lampreys exhibit remarkable adaptability through a combination of extensive gene flow [6] among populations, morphobiological flexibility in response to varying environments, [7] and evolutionary conservation of neuropeptide Y receptors, [8] which together support their survival across diverse and changing arctic habitats. The adults live in freshwater habitat near the coast, such as rivers and lakes. It can be found over stony and sandy substrates, and shelters under vegetation. [1]

Behaviour

The adult Arctic lamprey spawns in the gravel of riffles. The ammocoetes, as the lamprey larvae are known, are found in muddy freshwater habitats where they burrow in the mud and feed on detritus. It is generally an anadromous species, living in the ocean before migrating to fresh water to spawn, but some populations are permanent residents of fresh water. [4]

The adult is generally a parasitic feeder that attaches to any of a number of other fish species, [4] including salmon, lake trout, and lake whitefish. [9] The smaller, non-migratory form is not parasitic. [9] The juvenile consumes aquatic invertebrates, algae, and organic debris. [4] This species is prey for other fish such as inconnu, northern pike, and burbot, and gulls feed on spawning aggregations. The eggs and larvae are food for sculpins. [9]

Status

The Arctic lamprey is a commercially important edible fish with fatty flesh. It is reared in aquaculture. [4] The ammocoetes are used as bait. Threats to the spawning habitat of this species include pollution and the regulation of water flow by damming. Nevertheless, the IUCN has assessed this species as being of "Least Concern". [1]

<i>Lethenteron appendix</i> 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 silver lamprey is a lamprey commonly found in the Northern and Central United States, as well as a large part of southern Canada. Its binomial name means "sucking fish" in Greek and "one-pointed" in Latin. The silver lamprey is a member of the class Agnatha, sometimes referred to as cyclostomes (round-mouths). Other common names include: bloodsucker, blue lamprey, hitch-hiker, lamper, lamprey eel, northern lamprety. The silver lamprey should not be confused with the sea lamprey, which has caused considerable damage to native fish populations in the Great Lakes region.

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.

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.

<i>Mordacia lapicida</i> Species of jawless fish

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.

<i>Lampetra ayresii</i> Species of jawless fish


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.
