Gray Kangaroo

Gray kangaroos are large Australian marsupials that include eastern and western gray kangaroo forms. Mature males commonly weigh about 120–150 pounds or more, while females usually weigh about 60–90 pounds. They are gray to brown-gray with long tails, powerful hind legs, large ears, and a hopping gait adapted for efficient travel across open country. Gray kangaroos are social grazers that live in groups called mobs and feed mainly on grasses and herbs. In the United States, they have been kept in zoos since the early 20th century, with private exotic animal ownership and educational facilities becoming more visible later in the 20th century.
