Freshwater resident populations in Slave, Hay and Mackenzie rivers, Northern Territories, Canada. Freshwater non-migratory stocks in river systems in Mongolia (Ref. 41072). In danger of local extinctions due to pollution and use as bait (Ref. 12321).

Short description

Characterized by 2 large teeth on the supraoral bars, the presence of only 2 points on the central pair of lateral tooth plates, and the presence of a row of posterial teeth (Ref. 27547). Dorsal fins arise far back on body, the anterior dorsal lower than the posterior, the fins higher in males; lower lobe of caudal fin is somewhat larger than upper, the fin joined to both dorsal and anal fins; anal fin small, in males represented only by a low ridge (Ref. 27547). Color ranges from brown to olive to grayish above, paler below (Ref. 27547). The non-anadromous form rarely grows larger than 18 cm (Ref. 27547).

Prefers 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).
