The Arctic hare is a species of hare highly adapted to living in the Arctic tundra and other icy biomes. The Arctic hare survives with shortened ears and limbs, a small nose, the fat that makes up close to 20% of its body, and a thick coat of fur. It usually digs holes in the ground or under the snow to keep warm and to sleep. Arctic hares look like rabbits but have shorter ears, are taller when standing, and, unlike rabbits, can thrive in extreme cold. They can travel together with many other hares, sometimes huddling with dozens or more, but are usually found alone, sometimes taking more than one partner. The Arctic hare can run up to 60 kilometres per hour (40 mph).
Thymallus is a genus of freshwater fish in the salmon family Salmonidae; it is the only genus of subfamily Thymallinae. The type species is Thymallus thymallus, the grayling. The species in the genus are generically called graylings, but without qualification this also refers specifically to T. thymallus.
Arctic grayling is a species of freshwater fish in the salmon family Salmonidae. T. arcticus is widespread throughout the Arctic and Pacific drainages in Canada, Alaska, and Siberia, as well as the upper Missouri River drainage in Montana. In the U.S. state of Arizona, an introduced population is found in the Lee Valley and other lakes in the White Mountains. They were also stocked at Toppings Lake by the Teton Range and in various lakes in the high Uinta Mountains in Utah, as well as various alpine lakes of the Boulder Mountain chain in central Idaho.
The Arctic shrew, also known as the blackback shrew or saddlebacked shrew, is a medium-sized shrew found in Canada and the northern United States. Separate species status has been proposed for the maritime shrew which is found in New Brunswick and Nova Scotia and had been considered to be a subspecies of the Arctic shrew. The tundra shrew was formerly considered to be a subspecies of the Arctic shrew.
Rubus arcticus, the Arctic bramble or Arctic raspberry, is a species of slow-growing bramble belonging to the rose family, found in arctic and alpine regions in the Northern Hemisphere.
Kotelny Island is part of the Anzhu Islands subgroup of the New Siberian Islands located between the Laptev Sea and the East Siberian Sea in the Russian Arctic. It is administratively and municipally part of Bulunsky District.
Marinobacter is a genus of Proteobacteria found in sea water. They are also found in a variety of salt lakes. A number of strains and species can degrade hydrocarbons. The species involved in hydrocarbon degradation include M. alkaliphilus, M. arcticus, M. hydrocarbonoclasticus, M. maritimus & M. squalenivorans.
