Three Red Kangaroos Lounging Royalty-Free Stock Photo

The red kangaroo is the world's largest marsupial. Females have one baby at a time, which at birth is smaller than a cherry. The infant immediately climbs into its mother's pouch and does not emerge for two months. Until they reach about eight months of age, threatened young kangaroos, called joeys, will quickly dive for the safety of mom's pouch. As they grow, joeys' heads and feet can often be seen hanging out of the pouch. Red kangaroos hop along on their powerful hind legs and do so at great speed. A red kangaroo can reach speeds of over 35 miles (56 kilometers) an hour. Their bounding gait allows them to cover 25 feet (8 meters) in a single leap and to jump 6 feet (1.8 meters) high.
