 Kangaroos live in Eastern Australia. They live in small groups, typically made up of 50 or more animals. Kangaroos belong to the animal family Macropus, literally 'big foot'. 
They posess powerful hind legs, a long, strong tail, and small front legs. Thanks to their large feet, kangaroos can leap some 9 metres in a single bound, and travel more than 48 kilometers per hour. With an average life span in the wild of up to 23 years, and weighing on average 90 kilograms, kangaroos are herbivores that survive on grass and small shrubs. They use their strong tails for balance while jumping. Kangaroos are the tallest of all marsupials, standing at almost 2 metres tall. 
If threatened, kangaroos beat on the ground with their strong feet as a warning. Fighting kangaroos kick opponents, and sometimes bite.
Female kangaroos have a pouch to cradle baby kangaroos called joeys. Newborn joeys are just 2.5 cm at birth, about the size of a grape. After birth, joeys travel unassisted through their mother's thick fur to the safety of the pouch. At about 4 months, the joey emerges from the pouch for short trips and to graze on grass and small shrubs. At 10 months, the joey is mature enough to leave the pouch for good. Besides humans and wild dogs called dingoes, kangaroos face few natural predators. Heat, drought, and hunger due to the vanishing habitat are the biggest dangers kangaroos face.
