Elk

life science Maturity 5-7 Next article →

The elk, also known as the wapiti, is a massive mammal within the deer family, Cervidae.

It is the second largest species in its family, following only the moose. These animals are among the largest land mammals in North America and parts of Asia. The name "wapiti" comes from Shawnee and Cree words meaning "white rump."

This refers to the light-colored fur near their tails. Elk use this patch to signal distress or agitation to other members of their group. They may also use it during courtship or when males are fighting for dominance.

Elk thrive in habitats like open forests and forest edges. They are herbivores that eat a variety of plants. They graze on grasses and sedges found on the ground. They also browse on higher vegetation, such as leaves, twigs, and bark.

To stay warm during the winter, elk grow a thick coat of hair. This heavy coat is shed by early summer. They often rub against trees to help remove the old hair from their bodies.

Male elk are known for their impressive antlers made of bone.

These antlers grow very quickly, sometimes at a rate of one inch per day. While they are growing, they are covered in a soft, vascularized skin called velvet. This velvet is filled with blood and nerves to protect the developing bone. The growth and retention of these antlers are driven by testosterone. When the weather warms in late winter or early spring, testosterone levels drop. This chemical change causes the elk to shed their antlers annually.

During the mating season, males engage in several ritualized behaviors. They use posturing to attract females and participate in antler-wrestling, which is called sparring.

Males also perform a vocalization known as bugling. Bugling is a loud series of whistles, bellows, and screams. These sounds help males establish dominance over rivals and attract mates.

This behavior is a key part of their reproductive cycle.

For a long time, scientists believed elk were a subspecies of the European red deer, *Cervus elaphus*. However, mitochondrial DNA studies beginning in 1998 changed this understanding.

These genetic tests proved that elk and red deer are actually distinct species. DNA evidence shows that elk are more closely related to sika deer than to red deer. You can distinguish them by their wider rump patches and paler antlers. Even though they can produce fertile offspring in captivity, they are biologically different.

There are many subspecies of elk across different continents. In North America, four subspecies remain: the Roosevelt, Tule, Manitoban, and Rocky Mountain elk.

The Roosevelt elk is the largest, with males weighing up to 1,100 pounds.

Some subspecies, like the Eastern elk and Merriam's elk, are now extinct. In Asia, there are subspecies like the Altai wapiti and the Manchurian wapiti. The Manchurian variety is darker and more reddish than others. Some researchers believe the Manchurian wapiti may eventually be classified as its own species.

Elk have a very broad history and a wide range of impacts. During the Late Pleistocene, prehistoric populations lived across Eurasia and into Western Europe. Today, they are native to North America and parts of Asia. They have also been introduced to places like Argentina and New Zealand. In these new locations, their high adaptability can sometimes threaten local ecosystems.

Because they belong to the order Artiodactyla, they are related to livestock like cows. This means they can sometimes transmit infectious diseases to or from domestic animals.
