Dozens of species of deer exist, including moose and reindeer. Deer live in a variety of habitats, and they can run and jump at great speeds, leaping up to 30 feet in a single bound.
White-tailed deer thrive in a variety of habitats from mountains to forests and grasslands, and they are even found in suburban neighborhoods. Although they are widely distributed throughout North and Central America, they are one of the smallest species of deer.
The moose is the largest species in the deer family, weighing in at between 1,100 and 1,500 pounds and standing 8 feet tall. These members of the deer family are found in the subarctic regions of the world such as northern Europe, Canada and Russia. The reindeer is a species of deer that also lives in colder regions.
Deer are herbivores, meaning they live exclusively on plants such as berries, nuts, leaves and grasses. A deer's stomach enables it to eat fibrous food, including twigs and even bark in times of food scarcity. Mule deer feed on plants such as junipers while caribous survive almost entirely on lichen and moss. The water deer grows tusks or fangs from its upper jaw instead of antlers.
