Why is australian fauna unique




















No need to worry about them if you are a bit careful. Most of these animals have flourished, spread all over the continent and became feral pests. You've heard about the feral rabbits, goats, foxes, cats?

These species all threaten the native fauna. Unfortunately, some unique Australian species have already become extinct. Australian camels belong to these introduced species. Although the numbers of feral camels have been increasing since their release into the Outback, it is widely accepted that their damage to the Australian environment is less serious. I hope you enjoyed this summary of unique Australian animals. Please come back when you get the chance. The animal section will be growing all the time.

The seeds of the berries, which are still intact, are sticky after passing through the digestive tract of the bird. These sticky seeds cling to the branch of their host tree and grow.

The parasitic mistletoe only grows high up on other trees and so this relationship ensures both the bird and bush can survive. The Tasmanian Devil, once seen throughout mainland Australia, can now only be found in Tasmania. Fox dens, for example, are very smelly and quite messy, so the devil can quickly sniff them out. Such helpful little devils! Learn about our impact in Australia, latest news and more.

The Echidna has porcupine-like spines, a bird-like beak, quoll-like pouch and lays eggs like a reptile. It also feeds their young on milk like all mammals but have no nipples — the milk just oozes out of the skin in the pouch and the puggle baby echidna licks it up. There are four species of echidnas, including the Short-beaked Echidna found throughout Australia in places like the Great Western Woodlands.

This family oriented bird does its communal call to establish the territory of the family unit and warn off other kookaburras. The family unit may vocalise together like a chorus to amplify their claim to their territory. If any rival families are within earshot they too may respond. Interestingly, researchers have found that members of a family unit laugh in a similar manner. The Numbat is an endangered small marsupial that survives in southwest Western Australia.

Due to its small size, the Numbat is hunted by many animals like feral cats, foxes, dingoes and birds of prey. Because it solely on termites which are active by day, the Numbat is the only diurnal opposite of nocturnal marsupial. It spends nights hiding in hollow logs or burrows that are too narrow for its predators to enter.

To further protect itself from predators at night, it uses its very thick-skinned rump to block the entrance. The Pellucid Hawk Moth is a unique species that looks like a cross between a moth, a cicada, and a Glasswing Butterfly. Very few species of Lepidoptera, the insect order which includes all butterflies and moths, have scaleless, transparent wings.

A long period of separation from the rest of the world has blessed Australia with its utterly unique fauna. Cut off from other continents for about 30 million years, our wildlife has evolved to suit the conditions here. Here's a breakdown of our incredibly unique animals and where you can find them.

Koala: These fluffy tree-dwelling marsupials are known for being lazy, sleeping hours per day. They spend the rest of their time eating, consuming up to one kilogram 2. Meeting a koala is one of Australia's most iconic animal experiences. Kangaroo: There are about 50 different types of kangaroos — including two that live in trees! Echidna: One of two monotremes egg-laying mammals in the world, these spiky animals look something like a hedgehog crossed with an anteater.

A baby echidna is adorably known as a puggle. Interestingly, their beaver-like tails are not used for swimming, but to store fat in case of a food shortage. Their friendly nature and adorable smiles have made them an internet sensation with many people snapping quokka selfies. Tasmanian devil: Living up to their namesake, these small, feisty carnivores are found in the southern state of Tasmania.

Among other fun facts , devils have powerful jaws used to devour their entire prey and are spectacular tree climbers. While they attack from underwater, salties actually have to bring their prey above water to eat. Australian waters are home to a celebrity humpback named Migaloo — an albino adult male. Keen whale watchers can spot him travelling along the east coast up to the Great Barrier Reef every year. Australian birds: A birdwatcher's paradise , Australia is home to 56 types of colourful parrots, the laughing kookaburra and even the planet's smallest penguin.

You will also find two of the world's largest and heaviest birds here — the emu and the cassowary. Australia has more than 40 species of kangaroo and wallaby, from the mighty red kangaroo to the teeny musky rat-kangaroo. If feeding a kangaroo or getting close to a koala is high on your bucket list, visiting one of our incredible zoos or wildlife sanctuaries is an excellent way to safely get up close and personal with our animal ambassadors.

In Australia, they can be found in every major city as well as many regional areas. Sanctuaries: Wildlife parks house many free-ranging native animals, where visitors can interact with wildlife in a semi-natural environment. Wildlife sanctuaries usually have a focus on rehabilitation or aim to protect certain threatened species. Many are also home to wildlife hospitals helping injured animals, especially after bushfires. Visit an aquarium to learn about our fishy friends and connect with informative guides and interpretive material.

Most major cities have an aquarium showcasing vibrant tropical fish, corals, turtles, mammals and even sharks. You can learn more about marine environments with our Exploring Our Ocean course. Distinctive marine species include the predatory great white shark, which grows up to six metres in length; the giant filter-feeding whale shark, which can reach lengths of up to 12 metres; and the box jellyfish, which is one of the most venomous animals in the world. Based on evolutionary history and fossil evidence from about million years ago, the world had just one huge super-continent called Pangaea.

Around 50 million years later, this super-continent broke up into two continents, known as Laurasia and Gondwana. When this separation took place, monotremes and marsupials were the predominant mammals of the Gondwana tropical forest region, while placental mammals evolved in Laurasia.

Then, about million years ago, in the Jurassic Period, the western half of Gondwana, which included Africa and South America, separated from the eastern half which included Madagascar, India, Australia, and Antarctica. Gradually or 40 million years later, India separated from Antarctica and Australia, creating the Indian Ocean.

Together, Australia and Antarctica slowly drifted to the southern region and thus became completely isolated from the rest of the world by vast oceans. Australia finally separated from Antarctica 50 million years ago. As it drifted away from the southern polar region, its climate became warmer and drier, and new species of animals evolved and came to dominate the landscape.

As it turned out, monotremes and marsupials, with their less demanding reproductive systems, were more suitable for this new environment and became the dominant animals in Australia. The animals which were originally on the Australian landmass no longer had contact with creatures from other parts of the world and so continued to evolve independently.

This separate evolution has resulted in some unusual Australian animals and is the reason why Australian native animals are so different from those found elsewhere in the world. Koalas live in eucalyptus tree branches and can sleep up to hours a day. While most Australian states prohibit koala cuddles, you can have this once-in-a-lifetime opportunity at three Australian states.

There are 55 different native species of kangaroos and wallabies — a smaller species of kangaroo. In their natural habitat, you will spot a kangaroo roaming the grassy areas of the bush, on beaches across the Australian coastline, or hopping across the red sand in the iconic Aussie outback plains. In some wildlife sanctuaries, you may be able to pat and feed them.

Dingos are wild dogs that are found across most of mainland Australia. For a personal dingo encounter, just south of Sydney at Symbio Wildlife Park , you can play around with adults and pups.
