are mammals that are also marsupials. They
live in Australia. Like other marsupials, their newborn are very
small and underdeveloped. After birth, one or sometimes two babies
find their way into the mother's pouch and become attached to
her nipples. There
they will grow and be kept safe. After a few weeks, the young
leave the mother's pouch but return to it for food and shelter.
They suckle the mother's milk and stay in the pouch until they
are weaned about seven months later. A baby kangaroo is called
have larger and stronger hind legs than forelegs. When kangaroos
move slowly, on all fours, they are supported by a triangle consisting
of the two front feet, the hind feet, and the tail for balance.
When running, they can leap in 25-foot (7.6 meters) strides, using
the hind feet alone and the tail as a counterbalance. Kangaroos
can travel 40 miles an hour for short distances. Hind feet of
all kangaroos have the second and third toes fused together. These
act as a comb for cleaning the fur. Its front feet can hold branches
when it eats leaves.
The red kangaroo
lives on the Australian plains, wallaroos in mountains, and the
gray kangaroo in forests.
