Animals That Live in Alaska

Known as ‘elk’ in some parts of the world, the moose (Alces alces) is an animal with a habitat distribution in the circumpolar regions. Alaska is found within this area and the subspecies Alce alce gigas, known as the Alaskan moose or Yukon moose, is one of the most common. They are the largest subspecies of moose. In fact, they are the largest of any species within the deer family. Learn more in our article about the different types of deer.

The Alaskan moose is also sometimes known as the giant moose. We can see why this is by looking at their weight. Males can weigh up to 771 kg (0.8 t) and females weighing up to 573 kg (0.6 t). They have a solid body, but relatively long and thin legs. Additionally, they possess large antlers that can span up to 1.8 meters (6 feet), which they use during mating rituals and to assert dominance.

This animal typical of Alaska has a wide distribution throughout the northern region. Their habitats are in coniferous or leafy forests, tundra further north, and taiga to the south. They generally prefer land with lakes, swamps, or wetlands, but they do not tolerate hot climates. If the temperatures rise, they tend to move away. The conservation status of the species is of least concern, according to the International Union for Conservation of Nature (IUCN). Their large size also makes them a key prey for predators like wolves and bears, playing a significant role in the ecological balance of their habitat.

This is the only species of mountain sheep that has horns. They are animals which display sexual dimorphism, seen in that males have larger, bulkier, and curlier horns than females. They are also distinguished by weight since males weigh between 73-113 kg (160-250 lb), while females are much lighter at between 46-50 kg (101-110 lb). Their fur is abundant and usually white, although certain coat variations exist. This thick coat helps them withstand the harsh winter conditions of their high-altitude habitats.

Dall sheep, also known as the thinhorn sheep, are native to Alaska and parts of Canada. In the USA, their habitat ranges in the northeast, center, and south. They tend to stay in dry areas with grasslands or bush. They can stay in places with lighter snowfall and strong winds which disperse snow. They are considered to be of least concern according to the IUCN. These sheep are agile climbers, using their keen sense of balance to traverse steep and rocky terrain, which helps them evade predators.

The otter is distributed in few regions, Alaska being one of them. One of the three existing subspecies, Enhydra lutris kenyoni, can be found in this region. In this subspecies the males are larger than the females, weighing 27-39 kg (60-86 lb), while females weigh 16-27 kg (35-60 lb). They have a brown to reddish colored double coat, which is important for the sea otter to bear the very low temperatures of the Alaskan waters. Their fur is the densest of any animal, with up to a million hair follicles per square inch, providing essential insulation against cold waters.

They are distributed in marine areas near the coast, which can have rocky or soft floors, but the abundant presence of algae is important. Although carnivorous, they look for food in and around the algae. The sea otter has been hunted for its fur in Alaska to the point they are now considered in danger of extinction. Conservation efforts are ongoing to protect their habitats and regulate hunting, emphasizing the critical role they play in maintaining the health of kelp forest ecosystems.

This marine mammal is anatomically well adapted to propel themselves fast while diving. When they are beneath the surface, they can slow down their heartrate to stay underwater for longer. Males measure from 1.60-1.90 m (5.2-6.2') and weigh between 80-170 kg (176-375 lb). Females do not exceed 1.70 m (5.5') in length and 145 kg (319 lb) in weight. Their streamlined bodies and flexible flippers make them agile swimmers, capable of quick turns and bursts of speed when pursuing prey.

The harbor seal has coastal habits and, in addition to North American, can be found in parts of Europe and Asia. Five recognized subspecies develop in different regions. For example, the subspecies known as Pacific common seals (Phoca vitulina richardsi) can be found in Alaska and other western parts of the country. This type of seal is considered of least concern. Their diet primarily consists of fish and invertebrates, and they play a vital role in the marine food web as both predator and prey.

This typical Alaskan animal is well adapted to living in freezing temperatures thanks to its abundant fur and thick skin. Most of the coat is white in winter and grayish or brown in summer, but there are also a few individuals with a gray-bluish coloration. The leather-like padding of their paws offers additional protection against the cold. They measure up to 70 cm (2.3') in length and has an average weight of 5.2 kg (11.5 lb). These adaptations are crucial for survival in their harsh environment, where temperatures can drop significantly.

The arctic fox inhabits the circumpolar regions, which includes Alaska, developing in the arctic and alpine tundra of this state. It also has a presence in the sub-arctic maritime ecosystem of some islands in the area. It is considered of least concern. The Arctic fox is just one of many Arctic animals you can learn about. Their opportunistic feeding behavior allows them to survive in the tundra, where they scavenge carcasses left by larger predators.

The snowy owl is a bird of the order Strigiformes. The white color predominates in adult males, but females also have brown spots. They are one of the largest owls in the world, with a wingspan of about 146 cm (4.7') in males and 159 cm (5.2') in females. The average weight of the former is 1.6 kg (3.5 lb) and the latter 2 kg (4.4 lb). Their silent flight and keen eyesight make them efficient hunters, primarily preying on small mammals and birds.

It is an iconic owl of the arctic regions, including Alaska. It develops in the open tundra, from the area near the tree line to the polar maritime edge. Due to the population decline, it has been classified as vulnerable by the IUCN. Conservation efforts focus on habitat protection and monitoring populations to ensure their survival in the wild. Their presence is also a key indicator of the health of the arctic ecosystem.

Some species of whales are part of the Alaskan fauna belonging to its oceans, such as the humpback whale. While it is not yet confirmed officially in taxonomic studies, there are three proposed subspecies of humpback whale^[1]. They are often found along the Alaskan coasts in summer. They are very robust and characterized by long pectoral fins. They are dark gray in the dorsal area and white in the ventral area. These whales are known for their acrobatic breaches and complex songs, which play a role in communication and mating.

The humpback whale is a cosmopolitan species that is widely distributed throughout the world's oceans, but it is considered part of Alaskan wildlife during the summer. With a growing population trend, it is considered to be of least concern. Learn more by looking at the different types of whales which can be found. Their migratory patterns are vital for nutrient cycling in the ocean, and they contribute to marine biodiversity by supporting a variety of marine life.

The Alaska marmot is an animal that is distinguished from the rest of its group by the presence of a dark coloration on the head, which extends over the nose and reaches the neck. The rest of the body can vary between brown, gray, and even white in coloration. Average weight and length are about 3.4 kg (7.4 lb) and 59 cm (2'), with males being larger than females. They are well adapted to their cold environment, with thick fur and a hibernation period that allows them to survive the harsh winters.

This species of marmot is a native animal of Alaska and has an important distribution in the Arctic tundra. Here they are found extensive rocky stretches, where they make dens to provide protection. Its population is stable and is considered to be of least concern. Marmots contribute to their ecosystem by aerating the soil through their digging activities, which also provides habitats for other species.

This sea lion is the largest that exists. Although males are larger than females, both are of robust build and immense dimensions. The maximum size registered for them has been 3.3 m (10.8') and they average 1 ton in weight for males. For females, they measure a maximum 2.5 m (8.2') and 273 kg (601 lb). Their coloration is distinguished from other sea lions by being light brown to yellowish, which they maintain even when wet. These colors help them blend into their coastal environments, providing some protection from predators.

They are present in several coastal regions, including the Gulf of Alaska. Although they can travel long distances, they generally prefer to stay on shore and dive to feed. They can also occasionally be found on sea ice. They are classified as Near Threatened by the IUCN. Conservation efforts focus on protecting their habitats and ensuring sustainable fish stocks, as they are crucial to the sea lions' diet.

This animal is adapted for arctic conditions and is characterized by short legs and a barrel-shaped body. They are covered with long fur and both males and females have horns. The latter weigh up to about 250 kg (550 lb), while the former weigh 320 kg (705 lb) on average. Their thick, shaggy coats and a layer of fat underneath provide insulation against the extreme cold, allowing them to thrive in their frigid habitats.

Previously, the muskox was distributed in Canada, Greenland, and Alaska, but by the end of the 19th Century it disappeared from the latter region. However, they were later reintroduced, which is why today it is also considered part of Alaskan wildlife. They live in the arctic tundra tree line and are now considered to be of least concern. Muskoxen form social groups that help them protect against predators like wolves, and their grazing helps maintain the health of the tundra ecosystem.
