NATURE'S LOVABLE TEDDY BEARS

…..Cuddle koala bear of Australia is sometimes called ..... living Teddy bear. Only found in ..... Australia, koalas are also called ....."native bear" and "kangaroo bear".

The koala, however, is not really ..... bear; like the kangaroo and the opossum, it is ..... marsupial. Because of its cuddly appearance, it has been used as а model for our stuffed toy Teddy bears.

..... koala is dressed in ..... coat of thick fur, it has ..... round roly-poly body, ..... short legs, ..... small eyes, ...... rubber-like protruding black nose and ..... large fluffy ears.

...... healthy specimen weighs about 301b and stands about two feet. Its bright eyes constantly look at ..... world with a surprised expression. And koalas really enjoy being cuddled like teddy bears.

Very few of these living teddy bears have been exported to ….. zoos outside Australia because of ….. food they need to keep alive.

They flourish only when they can dine on ..... leaves of certain eucalyptus trees; which grow only in Australia. Other food is poisonous to them, resulting in ..... death.

Koalas get all ..... moisture they need from ..... leaves they consume; which is about 1 kg ..... day. They seldom drink any liquids, and their name "koala" comes from ..... native expression meaning "no drink".

..... giant tree may provide shelter and food for several koalas, but generally they live one to ...... tree. They are not even likely to be on visiting terms with their next-tree neighbour, living rather solitary lives except at mating time.

..... mother koala bear, like the kangaroo, has ...... built-in nursery. When baby koala is born he is sheltered for several months in his mother's pouch. After that ..... young koala buries its hooked claws in its mother's fur and rides pick-a-back.

When ..... danger threatens and ..... mother has to climb quickly ..... young one climbs around to mother's back, so as not to be in her way. There it hangs on securely while mother koala climbs to ..... safety.

If ..... young koala is disobedient, ..... mother knows what to do. She turns ..... naughty koala over her ..... knee and spanks him with ..... flat of her paw. And no matter how he wails, mother continues her punishment till she feels he's had enough. Young koalas grow to ...... maturity in about four years and, if all goes well, will live about 20 years.

Koala bears are very friendly and amiable. ..... Hunters took ..... advantage of this and almost killed them all off for their fur.

Now they are considered one of Australia's most prized animals and ..... Australian Government has laws to protect them.

Their popularity with ...... children is understandable. With fluffy ears, shoe-button eyes and furry body, they look like ..... Teddy bears that have escaped from ..... play-room.
