Chionophiles are any organisms (animals, plants, fungi, etc.) that can thrive in cold winter conditions (the word is derived from the Greek word chion meaning "snow", and -phile meaning "lover"). These animals have specialized adaptations that help them survive the harshest winters. [1]
Animals such as caribou, Arctic hares, Arctic ground squirrels, snowy owls, puffins, tundra swan, snow geese, Steller's eiders and willow ptarmigan all survive the harsh Arctic winters quite easily and some, like the willow ptarmigan, are only found in the Arctic region.
Antarctica, also known as the southern pole, is larger and can become much colder than the northern pole. As a result, few animals can survive on the mainland of Antarctica, and those that do mostly live near the coast. The few animals that live on the mainland are birds such as Antarctic terns, grey-headed albatross, imperial shag, snowy sheathbill and the most well known inhabitant of Antarctica, penguins. The inhospitable environment helps to deter predators; the few predators that hunt on the mainland, including the south polar skua and the southern giant petrel, mainly prey upon chicks. Most Antarctic predators are found in the polar waters, including the orca and the leopard seal.
Normally when colder conditions arrive, animals go into a state of suspended animation called hibernation, when they go into a state of inactivity for long periods of time, which they do not come out of until more suitable conditions for them to survive in arrive. However, when animals live in an environment that is inhospitable for much of the year, then hibernation is not necessary. One of the few animals that does so are lemmings, which have a mass migration after they come out of dormancy. However, most animals living in the arctic would still be active, even during the most brutal times of winter. Aquatic animals such as Greenland shark, wolf fish, Atlantic cod, Atlantic halibut and Arctic char must cope with the sub-zero temperatures in their waters. Some aquatic mammals, such as walrus, seal, sea lion, narwhals, beluga whales and killer whales, can store fat called blubber that they use to help keep warm in the icy waters. Some ungulates that live in frigid conditions often have pads under their hooves to help have a stronger tension on the icy ground or to help in climbing up on rocky terrain. But mammals that already have a pad under their foot such as polar bears, wolverines, Arctic wolves and Arctic foxes will have fur under their pads to help keep their flesh concealed from the cold. Other mammals such as the musk oxen can keep warm by growing long, shaggy fur to help insulate heat. And this can be quickly shed off when warmer temperatures arrive. But with the snowshoe hare it will change the color of its fur from white to brown or with patches of brown when it sheds off its winter coat. This is to help camouflage itself in its new environment to match with the dirt during the summer or back again when it regrows its longer white fur to match with the snow during the winter.
Other chionophiles can be found on or near the equator and yet still live in freezing temperatures. This is mostly due to their geographical range, such as on high altitude mountains where it can reach very cold temperatures and have less oxygen the higher the altitude. These may include the Andes, the Himalayas and the Hindu Kush mountains, where animals such as snow leopards, pumas, wild yaks, mountain sheep, mountain goats, ibex, vicuñas and guanacos can thrive.

The following animals are known chionophiles:
The skuas are a group of predatory seabirds with seven species forming the genus Stercorarius, the only genus in the family Stercorariidae. The three smaller skuas, the Arctic skua, the long-tailed skua, and the pomarine skua, are called jaegers in North American English.
The Antarctic Sound is a body of water about 30 nautical miles long and from 7 to 12 nautical miles wide, separating the Joinville Island group from the northeast end of the Antarctic Peninsula. The sound was named by the Swedish Antarctic Expedition under Otto Nordenskjöld for the expedition ship Antarctic which in 1902, under the command of Carl Anton Larsen, was the first vessel to navigate it. Since 1998 cruise ships have been visiting the area.
Admiralty Bay is an irregular bay, 8 km (5 mi) wide at its entrance between Demay Point and Martins Head, indenting the southern coast of King George Island for 16 km (10 mi), in the South Shetland Islands of Antarctica. The name appears on a map of 1822 by Captain George Powell, a British sailor, and is now established in international usage. The Henryk Arctowski Polish Antarctic Station is situated on the bay, as is the Comandante Ferraz Brazilian Antarctic Base. It has been designated an Antarctic Specially Managed Area.
Scoresby Sound is a large fjord system of the Greenland Sea on the eastern coast of Greenland. It has a tree-like structure, with a main body approximately 110 km (68 mi) long that branches into a system of fjords covering an area of about 38,000 km2 (14,700 sq mi). The longest of the fjords extends 340–350 km (210-216 mi) inland from the coastline. The depth is 400–600 m (1,310-1,970 ft) in the main basin, but depths increase to up to 1,450 m (4,760 ft) in some fjords. It is one of the largest and longest fjord systems in the world.
Half Moon Island is a minor Antarctic island, lying in McFarlane Strait 1.35 km (0.84 mi) north of Burgas Peninsula, Livingston Island in the South Shetland Islands of the Antarctic Peninsula region. Its surface area is 171 hectares. The Argentine Cámara Base is located on the island. It is only accessible by sea and by helicopter; there is no airport of any kind. The naval base is operational occasionally during the summer, but is closed during the winter.
This is a list of the fauna of Finland. Finland borders Sweden to the west, Russia to the east, and Norway to the north, while Estonia lies to its south across the Gulf of Finland, allowing an ecological mix. Finland contains many species of mammals, birds, and fish, but only a few reptiles and amphibians. This article discusses all the vertebrate animals which can be found on Finland itself, not the oceans.
The Southern Indian Ocean Islands tundra is a tundra ecoregion that includes several subantarctic islands in the southern Indian Ocean.
Bluenose Lake is a lake in Kitikmeot Region, Nunavut, Canada. It is located north of the Arctic Circle within the large, shallow basin of the Melville Hills. It is approximately 33 mi (53 km) long, 12 mi (19 km) wide, and is situated at 1,800 ft (550 m) above sea level. The Croker River flows north from Bluenose Lake to the Arctic Ocean, entering at Dolphin and Union Strait.
Seymour Island is an uninhabited island in the Qikiqtaaluk Region of northern Canada's territory of Nunavut. A member of the Berkeley Islands group, it is located approximately 30 mi (48 km) north of northern Bathurst Island. Between Seymour Island and Bathurst Island lies Helena Island. Penny Strait lies about 90 km (56 mi) to the east where open water polynyas occur.
The Arctic coastal tundra is an ecoregion of the far north of North America, an important breeding ground for a great deal of wildlife.
Lions Rump is a conspicuous headland 2 km (1.2 mi) north-northeast of Low Head, forming the west side of the entrance to King George Bay, on King George Island, in the South Shetland Islands of Antarctica. It was charted and given its descriptive name in 1937 by Discovery Investigations personnel on the Discovery II. Chopin Ridge runs between Lions Rump and Low Head. The rock feature known as "Martello Tower" lies 4 km (2.5 mi) to the north-northwest.
The fauna of Illinois include a wide variety of mammals, birds, amphibians, reptiles, fish and insects.
The Southern Powell Island and adjacent islets Specially Protected Area is a 2688 ha site encompassing part of southern Powell Island in the South Orkney Islands of Antarctica. It includes neighbouring Christoffersen, Fredriksen, Michelsen and Grey Islands, along with some other (unnamed) offshore islets. It was designated an Antarctic Specially Protected Area because of its biological values as it supports many plants and animals that exemplify the natural ecology of the South Orkney Islands. It is also a breeding site for Antarctic fur seals.
