Red kangaroos live in the deserts and open grasslands of Australia. They live in groups called mobs, and their population is well over a million strong as of 2014.
Red kangaroos are the largest marsupials in the world. They stand 3.25 to 5.25 feet tall and can weigh up to 200 pounds. The females are smaller and faster than the males and carry their newborns in a pouch on their stomach for up to eight months. Males are well-muscled and often fight over mates with competing males. They are able to lean back on their thick tails and box each other with their powerful hind legs.
