| Biology |
Adults inhabits coastal and estuarine waters (Ref. 59043). Prefer sites with stony or sandy bottom, shaded by riparian vegetation (Ref. 41072). Spawning adults found in gravel riffles and runs of clear streams; feeding adults usually in oceans or lakes; ammocoetes in muddy margins and backwaters of river and lakes (Ref. 5723). Anadromous (Ref. 58426). There are non-migratory freshwater populations. Probably parasitizes any species of fish of suitable size (Ref. 27547), including commercial species (Ref. 58426). Subadults are non-parasitic (Ref. 12218). Feed on small aquatic invertebrates, algae and organic matter contained in detritus (Ref. 41072). Arctic lamprey has high quality flesh rich in fat (Ref. 41072). |

| Distribution |
Arctic: Siberian coast to Anderson River in Canada. Northwest Pacific: Bering Sea south to Japan and Korea. Freshwater resident populations in Slave, Hay and Mackenzie rivers, Northern Territories, Canada. Freshwater non-migratory stocks in river systems in Mongolia (Ref. 41072). Europe: Arctic, White and Barents Sea basins of Russia and Norway, from Pechora drainage in Russia to Pasvik drainage in Norwegian-Russian border (Ref. 59043). In danger of local extinctions due to pollution and use as bait (Ref. 12321). |
