Red kangaroos are the largest marsupials in Australia. A
marsupial is an animal whose young develop in pouches. Male red kangaroos
(sometimes called boomers) are, as their name suggests, a reddish colour.
However, females (or blue fliers) are generally grey. An adult kangaroo
can grow to over 1.8 metres (6 feet) tall!
Kangaroos have extremely powerful z-shaped back legs and long feet.
Large tails help them balance as they jump and are used as a third leg
when they move more slowly. Kangaroos use their small front legs for
grooming and eating. They often lick their forearms to help them keep
cool.
