Animals In Australia

A kangaroo is one of the few marsupial. In common use the term is used to describe the largest species from this family, the Red Kangaroo, the Antilopine Kangaroo, and the Eastern and Western Grey Kangaroo of the Macropus genus. The family also includes many smaller species which include the wallabies, tree-kangaroos, wallaroos, pademelons and the Quokka, some 63 living species in all. Kangaroo is a typical animal in Australia and it symbolises it on many occasions, for example, post marks and state crests.

In general, larger kangaroos have adapted much better to changes wrought to the Australian landscape by humans and though many of their smaller cousins are endangered, they are plentiful. They are not farmed to any extent, but wild kangaroos are shot for meat, sport, and to protect grazing land for sheep and cattle. Although there is some controversy, harvesting kangaroos for meat has many environmental and health benefits over sheep or cows grazed for meat.

People from outside Australia, who have seen kangaroos for the first time described them as very strange animals. That's not odd, because there are no animals alike outside Australia. Early explorers described them as creatures that had heads like deer (without antlers), stood upright like men, and hopped like frogs. Combined with the two-headed appearance of a mother kangaroo, this led many back home to dismiss them as travellers' tales for quite some time. The first kangaroo to be exhibited in the western world was an example shot by John Gore, an officer on Captain Cook's Endeavour in 1770. The animal was shot and its skin and skull transported back to England whereupon it was stuffed (by taxidermists who had never seen the animal before) and displayed to the general public as a curiosity.

Kangaroos have large, powerful hind legs, large feet adapted for leaping, a long muscular tail for balance, and a small head. Like all marsupials, female kangaroos have a pouch called a marsupium in which joeys complete postnatal development.

Before European settlement, the kangaroo was a very important animal for Australian Aborigines, for its meat, hide, bones and sinews. In addition, there were important Dreaming stories and ceremonies involving the kangaroo. Aherrenge is a current kangaroo dreaming site in the Northern Territory. The game of Marn grook was played using a ball made from kangaroo by the Kurnai people.

Unlike many of the smaller macropods, kangaroos have fared well since European settlement. European settlers cut down forests to create vast grasslands for sheep and cattle grazing, added stock watering points in arid areas, and have substantially reduced the number of dingoes.

Kangaroos are shy and retiring by nature, and in normal circumstances present no threat to humans. Male kangaroos often "box" amongst each other, playfully, for dominance, or in competition for mates. The dexterity of their forepaws is utilised in both punching and grappling with the foe, but the real danger lies in a serious kick with the hindleg. The sharpened toenails can disembowel an opponent.

There are very few records of kangaroos attacking humans without provocation; however, several such unprovoked attacks in 2004 spurred fears of a rabies-like disease possibly affecting the marsupials. The only reliably documented case of a fatality from a kangaroo attack occurred in New South Wales, in 1936. A hunter was killed when he tried to rescue his two dogs from a heated fray. Other suggested causes for erratic and dangerous kangaroo behaviour include extreme thirst and hunger.

In 2003, Lulu, an Eastern Grey, saved a farmer's life. She received the RSPCA National Animal Valor Award on May 19 of the next year.

Occasionally, individuals take on the task of rearing a recovered joey themselves. The rule-of-thumb says that if the joey is already covered with fur at the time of the accident (as opposed to still being in its embryonic stage), it stands a good chance of growing up properly. Lactose-free milk is required, otherwise the animal may develop blindness. They hop readily into a cloth bag when it is lowered in front of them approximately to the height where the mother's pouch would be. The joey's instinct is to "cuddle up", thereby endearing themselves to their keepers, but after hand-rearing a joey, it cannot usually be released into the wild and be expected to provide for itself immediately. Usually wildlife sanctuaries are willing to adopt kangaroos which are no longer practical, or have grown too large to contain, needing at least 1-acre (4,000 m2) and 7 ft (2.1 m) boundary fences for a fully grown kangaroo.
