Close relatives to the reindeer family are...
The moose is the largest and heaviest species in the deer family. Unlike other deer, they are solitary animals and do not live in herds. They are easily distinguished by the broad, flattened, open-handshaped antlers sported by the males, which are known as palmate antlers.
Also known as the wapiti, the elk is one of the largest land mammals found in North America and eastern Asia. It has a reddish-brown fur coat and mostly lives and forages in forests. Like reindeer, elk shed their antlers after mating season and regrow them each year.
A surprising relative of the reindeer is the smallest deer on Earth, the southern pudú. This tiny deer is just 44 centimetres (17.3 inches) tall and is found in the rainforests of Argentina and Chile. Like the reindeer, pudús have antlers, but they are much smaller at just nine centimetres (3.5 inches) long.
