The moose (Alces alces) is the largest and heaviest living species of deer.

In North America, it is the second-largest land animal by body mass. Only the American bison is heavier. Most adult males are called bulls, while adult females are cows. Young moose are called calves.

These massive animals live in the cool forests of the Northern Hemisphere. They thrive in subarctic climates and temperate broadleaf forests. You can find them in Canada, Alaska, and parts of Europe and Russia.

Moose are mostly browsers, meaning they eat many kinds of plants. Their diet changes depending on the season. In the winter, they eat branches, twigs, and dead wood. They also eat aquatic vegetation from water.

To help them eat underwater, they have a unique proboscis. This is a large nose with nostrils that can seal shut. This allows them to browse plants in water without inhaling it. Their nose also provides a keen sense of smell. This helps them find food under snow or detect predators.

One of the most striking features of a bull moose is its antlers. Unlike the twig-like antlers of other deer, most moose have palmate antlers. This means they are broad and shaped like an open hand.

These antlers grow very quickly in the spring. They are covered in a soft skin called velvet. This velvet contains many blood vessels to nourish the growing bone. By September, bulls rub the velvet off by thrashing against trees. After the autumn mating season, bulls drop their antlers to save energy. They grow a brand new set every spring.

Moose have unique physical traits that help them survive in their habitats. Their feet are designed for soft ground and snow. They are even-toed ungulates, meaning they have two large keratinized hooves. Under heavy weight, these hooves splay outward. This increases the surface area of the foot. This prevents the moose from sinking into deep snow or soft mud. This foot structure also makes them efficient swimmers.

Different types of moose exist across the globe. The Alaskan subspecies, Alces alces gigas, is the largest race. An Alaskan bull can stand over 2.1 meters high at the shoulder.

These large males can have an antler spread of over 2 meters. In Europe, moose are often called elk. Northern European moose usually have palmate antlers. However, moose in southern Europe often have smaller, dendritic antlers. These antlers look more like twigs. This difference may be due to evolutionary pressure from human hunting.

Humans and moose have a very long history together. Evidence shows humans hunted moose as far back as the last Ice Age. In North America, moose were a vital source of food for many Indigenous people. The word "moose" entered English around 1606 from Algonquian languages. In Eurasia, the word "elk" is commonly used. The name "elk" has been used in Europe for centuries. Over time, the meaning of the word "elk" in English became vague. By the 1700s, some dictionaries described it simply as a deer as large as a horse.

Moose are generally solitary animals that live alone. They do not live in herds like many other deer species. A cow will stay with her calf for about 18 months. After this, she will chase the calf away. While they are often slow-moving, they can be very fast if startled. They can also become aggressive to defend themselves. This is most common during the autumn mating season. During this time, bulls engage in energetic fights to compete for females.
