Loodan, et käesolev referaat annab üldise ülevaate koalade elust. 1.2 Ajalugu ja levila «Koala» tähendab Uus-Lõuna-Walesi suguharude keeles «ei joo». Koalat on esimest korda mainitud tundmatu autori poolt, tema aruandes reisist Sinimägedesse 1798. aastal. Samal aastal lasi esimese tõendusmaterjali kuberneri sekretär John Price. Tundmatu autor kirjutab et Sinimägedes elab loom nimega kullavain, kes välimuselt sarnaneb Lõuna Ameerika laisikuga. Teadusele avastati koala merelaevastiku ohvitseri F. Ballieri poolt 1802. aastal. Esiteks muretses ta koalanaha, hiljem aga ka elusa looma. Pärast seda leiti viiekümne aasta vältel koalasid ainult Uus-Lõuna-Walesi piires, kuid 1855. aastal nähti teda ka Victoria osariigis ja 1923. aastal Queenslandi kaguosas. Minevikus asustas koala ka Lõuna- ja Lääne-Austraaliat, aga ta kas suri hijem välja või hävitati täielikult, sest leiud tõendavad, et ta seal elas. Queenslandist on leitud ka pool tonni kaalunud
Endangered animal koala bear Though often called the koala "bear," this cuddly animal is not a bear at all, it is a marsupial. Koalas live in eastern Australia, where the eucalyptus trees they love are most plentiful. In fact, they rarely leave these trees. That is why they are usually called "treehuggers". Koalas have thick, grayish fur, with white on their chests, inner arms, and ears. They have large furry ears and leathery noses.The koala has large, sharp claws to assist with climing tree trunks. The koala is one of the few mammals that have fingerprints. Koalas do not live in big groups, they rather prefer to be alone. Koalas consume eucalyptus leaves and bark from 12 different eucalyptus tree species. Koalas rests motionless for about 16 to 18 hours a day, sleeping most of that time. They can be aggressive towards each other, throwing a foreleg around their opponent and biting.
KANGAROO, KIWI AND KOALA Canada is north of the USA. It is a very big country. There are a lot of forests there. The maple leaf is the symbol of Canada. The people in Canada speak English or French. Ottawa is the capital of that contry. The Niagara Falls are two waterfalls on the border between the USA and Canada. The American Falls are in the States and the Horseshoe Falls are in Canada. A lot of tourists visit the falls every day. Australia is a warm country. Kangaroos and koalas live there. In Australia the summer months are December, January and February and the winter months are June, July and August. The Australian people speak English. The kangaroo is the symbol of Australia... New Zealand is east of Australia. There are more sheep than people in New Zealand. The people of New Zealand speak English. The kiwi, a bird which cannot fly, is the symbol of New Zealand.
Koala Koala pikkus on umbes 70-80 sentimeetrit. Ta kaalub kuni 16 kilogrammi. Tema välimus on väga kummaline: kohev karv, tillukesed silmad, alati kikkis kõrvad, naljakas lapik ja kongus nina. Koala karv on hallikaspruun või tuhkhall, seljal mõnikord punakas või hõbedane, kõhupoolel heledam.Koala kinnitub puu külge tugevate küünistega, mida ta vajutab puukoore sisse. Küünised on eriti tugevasti arenenud kahel teineteisele vastandataval varbal. Need on piisavalt tugevad, et kanda looma raskust. Tsüsiit, konjuktiviit ja sinusiit on koaalade tavalised haigused. Sinusiit tüsistub sageli, eriti talvel, kopsupõletikuga. Koala toitub ainult mõnede eukalüptiliikide lehtedest
Koalas The koala is an arboreal herbivore marsupial native to Australia. It is easily decide by its strong, tailless body; round, fluffy ears; and large, spoon-shaped nose. The koala has a body length of 6085 cm and weighs 415 kg. Fur colour ranges from silver grey to chocolate brown. At the beginning of the 20th century people hunted Koala because their fur. Today this animal is under the protection but they still are in danger. Koalas from the northern populations are typically smaller and lighter in colour than the other. Most of their food consists of eucalypt leaves but sometimes they eat other leaves too. There is about 600 species of eucalypt, koalas eat only 30. Because they get so little energy from their diet, koalas must limit their energy use and sleep 20 hours a day. They typically eat and sleep in the same tree

Koala The Koala is another recognised symbol of Australia. It's difficult to take koala pictures because they sleep 20 hours a day. (They are permanently sleepy because of the chemicals in the Gum leaves). Emu It is quite common to see emu's in Australia.They are the second largest flightless bird in the world (just smaller than the Ostrich), but the emu is unchallenged as the stupidest of all creatures. In the tropics you can meet emus cousin cassowary.
Mammals of Australia · Australia has more than 378 mammal species . · It is the only continent in the world to still have all three of the major groups of mammals: monotremes, marsupials and placentals. · Some of the best-known animals are the kangaroo, koala, echidna, dingo, platypus, wallaby and wombat. · Monotremes - egg-laying mammals (nowadays found only in Australia and New Guinea) Marsupials - babies born in embryonic condition and kept firmly attached to a teat in a pouch or nestled behind a protective skin-flap while developing further Placentals - unborn young are nourished by a placenta and born at a more advanced stage, some still naked, blind and unable to walk for a week or two, others able to run on their day of

Koala on tiheda karvkattega omapärane loom, kes elab ainult Austraalias. Tema eripäraks on see, et ta toitub ainult eukalüptilehtedest, seetõttu kiskjad tema liha ei söö ja tema ainus vaenlane on inimene. Tohutu küttimise tõttu käesoleva sajandi alguses ja esimesel veerandil, mille põhjustas koala ilus ja kohev karusnahk, oli loom peaaegu välja surnud. Kuid tänu loomade oidamisele kunstlikes tingimusetes, ja inimestele, kes jälgisid väga tähelepanelikult looduses säilinud isendeid, hakkas olukord sajandi keskpaigas vähehaaval paranema. Nüüdseks on koalade arv tõusnud, kuid neid on siiski väga vähe. Koalad on looduskaitse all. Selle teema valisin, kuna mind huvitavad loomad ja tahtsin koalade kohta rohkem teada saada
I slaid I am going to talk about strange animals that live in Australia. II slaid Australian kangaroos are the most famous Australian animals, and they belong to the most recognisable icons in the world. Australians call them 'roos' and they can be found in all parts of Australia, not just in the Outback. Their young are called joeys. All kangaroos are herbivores and only eat plants. The biggest enemies of kangaroos are humans. III slaid The Koala is one of Australia's best known animals. It is an icon represented when promoting Australia to the tourist industry. Koalas are mainly found in the south east Australia. Koalas are often referred to as a Koala bear. However they are not a bear. The name Koala comes from an Aboriginal word. It means "no drink", as Koalas get enough fluids through the eucalyptis leaves they feed on. They do not move around much and are only active for about 2 hours of the day. IV slaid
income. Enviroment. Although most of Australia is semiarid or desert, it includes a diverse range of habitats from alpine heaths to tropical rainforests. Australian forests are mostly made up of evergreen species, particularly eucalyptus trees in the less arid regions, wattles replace them in drier regions and deserts as the most dominant species. Among wellknown Australian fauna are the monotremes (the platypus and echidna); a host of marsupials, including the kangaroo, koala, and wombat, and birds such as the emu and the kookaburra. The koala and eucalyptus form an iconic australian pair pair. Culture. Since 1788, the basis of Australian culture has been strongly influenced by Anglo-Celtic Western culture. Distinctive cultural features have also arisen from Australia's natural environment and Indigenous cultures. Since the mid-20th century, American popular culture has strongly
Australian animals are very beautiful animals. The kangaroo is a symbol of Australia. There are more than 50 kind of red kangaroos. Adults are often 2.0 meters long. Kangaroos eat grass and leaves. Kangaroos live in group of ,twelve. But there are more interesting animals .Koalas are sleepy and their colour is grey .Koalas' babies ride on mothers back till six months .They live on eucalyptus trees and sleep 18 hours! Koalas eat eucalyptus trees leaves, they don't drink. The word koala means "No water " .In the sea you can find crocodiles that are 5 or 6 metre long. They eat fish, animals and sometimes people.You must be careful .Echidna and platypus babies are born from eggs but drink milk .The echidna eat ants with it catches with it long fast tongue .The platypus has a wide bill like a duck and a wide flat tail .It swims well ,but stays under water for a few minutes and it shuts its eyes and ears first .The emu is another Australian bird which is two meters long

The smallest are thekangaroos that belong to the group called rat kangaroos. There are million of kangaroos in Australia. Another Australian marsupial is the wombat. It lives in burrows in grassland areas of Australia and Tasmania. It has short strong legs and long claws for digging burrows.Wombats live in groups and come out to look for food at night. They have poor eyesight but they can smell and hear very well. Their nearest living relatives are koalas. The koala is one of the best known Australian animals. They live in eucalyptus trees,sleeping for 18 hours and eating 1 kilo of leaves each day. They drink almost nothing they get water from the leaves of the trees.They eat leaves of only five of 500 different kinds of eucalyptus trees.Baby koalas spend the first three months of their life in their mother's pouch,which opens to the back. They come out when they are about six months old. The possum is a furry animal that lives in the trees of Australia

No wonder that Australia is the world's largest exporter of lamb and wool. FUN FACTS the national anthem is referred to as "Advance Australia Fair" 1/5 of the land is desert pubs occupy more land than the mines Australians love meat pies the zoo has no cages, which is awesome!!! the koala, emu, kookaburra and kangaroo originated in Australia more venomous snakes than any other continent Bob Hawke's name was listed in the Guinness Book of world Record in the year 1954, for having 2.5 pints of beer in 11 seconds time. Later Bob Hawke was also the Prime minister of Australia. Historical facts o How cool is this??

In the outback, there are some sheep and cattle ranches (property.) There are about ten times more sheep than people in Australia. Sheep are raised for wool and for meat. In Australia what Americans call a ranch is known as a station. Stations are very big. Some stations are so big they have to use planes to keep track of the animals. The most famous animals in Australia are marsupials. A marsupial is a mammal that has a pouch to carry its young. Some kangaroos can jump 30 feet. The koala sometimes stays in the same tree for days and is endangered. The Great Barrier Reef is also in Australia. It is made up of coral and algae. Coral are tiny invertebrate animals. The Great Barrier Reef is about 1250 miles long. There is a channel of water that separates the reef from the Queensland coast. It is the largest deposit of coral in the world. It is also the world's largest living structure. Australia's national sport is Cricket. Cricket is a little bit like baseball but it
In Northern Australia there is a tropical climate. The coastal areas have the biggest amount of rainfall. In most parts of Australia rainfall is very low. 6. Animals Australia is the only continent on earth where marsupials live; they are also known as pouched mammals and egglying mammals. Ordinary mammals live also in Australia and these mammals are mostly imported there. Marsupials are kangaroos, wombats, koalas, Tasmanian wolfs and Tasmanian devils. The Koala is found all along the eastern coast of Australia from near Adelaide to the southern part of Cape York Peninsula, and as far into the hinterland as there is enough rainfall to support suitable forests. They are the cutest and lovelies animals of Australia. Koala accepts humans but if you really disturb them, they become aggressive. The Koala lives almost entirely on eucalyptus leaves. Koala has very long arms and very well developed paws. It eats about 2 pounds leaves a day

Their young are born before they are fully developed. The kangaroo is born after being only seven weeks inside it's mother. It is completely blind and only an inch or an inch and a half long. It crawls into its mother's pouch and attaches itself to a nipple there. There it stays for almost three months, when it begins to stick its head out. It is six months old before it is big and strong enough to leave the pouch. Some of the marsupials in Australia look very much like higher animals. The koala, which looks like a live teddy bear, is not really a bear at all but a marsupial. Today Australian marsupials are dying out. Dogs, cats, and rabbits brought to Australia by men are rapidly destroying the gentler marsupials. Some day there may be nothing left of the ancient animals. Australia has around 800 species of birds, 400 of which are unique to this country. There are 55 species of parrots in Australia, and the birds are as numerous as they are colourful.

4 metres high. They can jump more than four metres and travel at seventy kilometres an hour. Kangaroos eat grass and leaves and live in groups about twelve. Everyone loves the sleepy gray koalas. Like kangaroos, they have s pouch on their fronts for their babies. After six months there, baby koalas ride on their mother's back. They live in eucalyptus trees, sleeping for eighteen hours, and eating one kilo of leaves, each day. They drink almost nothing. The word koala means "no water." In the seas and rivers of northern Australia crocodiles can be found. They are five or six metres long. They eat fish, animals, kangaroos - and sometimes people. There are more than 800 kinds of birds in Australia. The emu, which is two metres tall, is the second largest bird in the world. It cannot fly at all, but it can run at fifty kilometres an hour. Then there is the kookaburra, whose cry sounds like someone laughing, and the budgerigar, a
there for several months. The kangaroo is the most numerous among marsupials. There are more than 50 species of them. It's a furry animal that hops on its hind legs. An adult can measure 2,4 metres high. They can jump more than 4 metres and travel 70 km/h. The biggest are red kangaroos, grey kangaroos and wallaroos. The smallest are the kangaroos that belong to the group called rat kangaroos. They eat grass and leaves and live in groups of about twelve. The koala is one of the best loved Australian animals. The aboriginals named it "the animal that does not drink". They live in eucalyptus trees, sleeping for 18 hours, and eating 1 kilo of leaves and bark each day. Baby koalas are about the size of a bean when they are born. They move into their mother's pouch, which opens to the back. It comes out at the age of 6 months. The wombat lives in burrows in grassland areas of Australia and Tasmania. It has
pouch where they stay for several months. The most numerous among marsupials is the 4 kangaroo. There are more that 50 different species of them. Kangaroo is a furry and quite long animal who is known for its jumping. They can jump more than 4 meters and achieve 70 km/h. Kangaroos eat grass and leaves. The koala is one of the best-loved Australian animals. It is a small marsupial that lives in eucalyptus trees and it can sleep for 18 hours straight. The aborigines named it "the animal that does not drink", but it eats leaves and bark. The wombat is a small animal that has short, but strong legs and claws, which it uses for digging burrows. It lives on Tasmania, but also in burrows in grasslands of Australia. They do not see well, but they can hear and smell very well.
mama's pouch. They are born as small, bean-sized hairless babies that climb up into the safety of the pouch. After 33 weeks the little kangaroos have to leave the pouch. At top speed kangaroos can make 4m leaps and reach the velocity of 50 km/h. The long, heavy and powerful kangaroo tail makes it all possible by providing balance and stability. Only tree kangaroos can move their hind feet independently of one- another. The wombat is a marsupial rat. The koala or pouched bear lives in the gum- trees. It is the loveliest of all the Australian animals. The Tasmanian wolf and the Tasmanian devil, the only native carnivores of Australia, are almost extinct. The egg-laying mammals are the strangest of all Australian animals. They lay eggs like birds and feed their young with milk like mammals do. They form a link between birds and mammals. The duck-bill or platypus lives in the rivers of East Australia mostly. The

Füsioloogiline muutlikkus - näiteks võime muuta kiiresti värvust (adapteeruda keskkonnale). Ja kasvõi meie higistamine soojas ja värisemine külma käes. Kalade võime reguleerida soola sisaldust organismis - kuid on vaid vähe kalu, kes on võimelised elama ühtviisi hästi nii soolases merevees, kui ka magedas vees.
