Australia has a vast and fascinating amount of animals, and is home to some of the most unusual creatures on Earth. It is one of the few continents to have all three groups of mammels —monotremes, marsupials, and placentals. Australia is also home to more than 800 species of birds, over 4,000 fish species, 50 different marine mammals, and two types of crocodiles. The continent has an expansive variety of ecosystems and habitats, such as sub-tropical rain forests in the Northeast, an immense span of desert and semi-arid land in Central Australia, and barren grasslands and towering mountain ranges scattered around the entire region. Approximately 90% of animals native to Australia and found nowhere else, such as the koala, kangaroo, dingo, platypus, …show more content…
A majority of the animals indigenous to Australia are marsupials, or animals whose young develop in a pouch instead of a placenta. These babies are not able to fend for themselves, so they live in a pouch in their mothers' bellies, where they feed on milk and grow until they can survive outside. Of the 238 species of mammals living in Australia, 144 are marsupials, and 90 percent of these are found in Australia. The continent is also home to the only egg-laying mammals in the world, the echidna and the odd duckbill platypus. Echidnas and small, solitary animals coated in bristles and spicules. Superfically, they resemble anteaters, or hedgehogs. They are usually brown or black in coloring; however albino echidnas have been reported. They have elongated and slender snouts that function as both a nose and …show more content…
The platypus has a flattened torpedo-like body, dense waterproof fur, and strong front legs used for both swimming and digging. Its head is narrow, each ear hidden in a groove next to its small eyes. While submerged to feed, the senses of sight, smell, and hearing are essentially shut down, so the creature uses its electroreceptors to navigate perfectly underwater. One of the platypus’ main predators is the crocodile, another aquatic animal commonly found in Australia. Crocodiles have a very low metabolism and move very little, in addition to being a "cold blooded" animal, which means they do not maintain a regular body temperature. That adds up to low energy consumption, so they, therefore, seldom need to eat. Their diet includes mollusks, crustaceans, insects, crabs, crayfish, shrimp, amphibians, reptiles, and fish. Among mammals, crocodile prey on wild boar, kangaroos, water buffaloes, goannas — monitor lizards, birds, horses, zebras, yaks, barasingha — swamp deer, deer, bats, gaurs—a type of bison, sharks, domestic livestock, monkeys, and dingoes. Large crocodiles can ambush and kill cattle and horses as they come to drink at
They have many kinds of spiders (Funnel Webs, Redneck Spiders, and the Mouse spider), types of fishes , and many mammals (Kangaroos, Dingos, and Koalas). They also have the most dangerous and deadly animals in the world. One of my favorite types of fishes from Australia is the stone fish, its dangerous and very poisonous but looks just like a stone which makes it a very cool
They are also have a muscular build and are nocturnal. These qualities enable them to prey on their
The increasing aridity of the Australian continent over the past 20 million years has favoured organisms that could adapt to dry conditions. Marsupials have developed a variety of behavioural, physiological and morphological adaptations to survive in these arid conditions with little or no food and free water for extended periods of time.
Western grey kangaroos are strong bipedal hoppers that live in many environments such as woodlands, grass lands, open forests, scrubland and heathland (Dawson, Milne & Warburton, 2014).
This Ecology Essay is about Koalas being endangered. They are mainly endangered in Southeastern and Eastern Australia the State of Queensland, New South Wales, South Australia and Victoria. This essay will talk about how they eat, their habitats, the threats, invasive species, population and density, trophic levels, nutrient cycles and human interaction.
Kangaroos tend to go for habitats with more moisture so they mainly hang in the woodlands, which also provides shade. However, when they want to graze or find food, they will go out to the grasslands. Their neighboring species include of koalas, tasmanian devils and platypuses. They have few predators, but the main 2 are humans and
They live mostly in south and southeastern parts of Australia because the temperature of the northern parts makes it tough to survive in winter.
1. Description: Red Kangaroos are the largest in size of the marsupials and the largest group in population of kangaroos still in existence. Males are a reddish brown and have a pale stomach and legs. Females are more of a greyish-reddish-brown color. They, like other kangaroos, have large, powerful hind legs and feet. Red kangaroos’ front legs are short, but they have a sturdy, muscular tail that supports the rest of their body.
Tasmanian Tigers are an extinct animal back in 1936. A striped creature that showed characteristics of a dog or wolf. To find out this animal was not that much related to a canine. Ir ended up looking and changing because of its ecological role play that it adapted. This article explains how and why a scientist went back did brain scans to figure out more about this mysterious animal. After scan both white and gray matter of the brain. To then find out interesting characteristics that were never research before because of its extinction in 1936. After this research it was founded that they are more like a tasmanian devil. Finding this was all because of the brain scan that Dr. Berns did. With this research it was founded that many people who
Western Australia lies in the southern hemisphere and is over 2.5 million square kilometres which is about the size of Western Europe. Western Australia cover approximately one third of Australia and is one of the largest states in the world with a wide range of fauna, flora, climate and history.
The red kangaroo is famous for being in the Australian icon.It is found across central
Almost all mammals give birth to live young but platypuses lay eggs. Platypuses are part of a primitive species of mammals called monotremes. When a female platypus is ready to give birth, she will bury herself inside one of her tunnels and seal herself inside. She will continue on to lay one or two eggs and keep them warm with her fur. After about ten days, the eggs hatch bean sized baby platypuses and the mom will nurse them for three to four months until they can swim on their
The first time rabbits arrived in Australia was on the first fleet. However, the first time they were seen was in 1827. In 1859 Thomas Austin freed about 12 rabbits on his property near Geelong, Victoria. The rabbits didn't just stay in the farm, eventually got to the QLD - NSW border two years later. "feral rabbits are now found all over Australia, apart from the northern most areas" (Environment.gov.au, 2017) Rabbits have the ability to survive in many different conditions, in fact they have been found to live in a lot of different habitats such as deserts to coastal plains, in fact they can survive nearly anywhere that has suitable soil for digging warrens. However rabbits have many predators such as dingoes or house cats.
Ultimately, the Kangaroo has to be Australia’s most famous and significant icon, it is known by the
Kangaroos have adapted to drier conditions and have features that help them deal with lack of water in the savanna. As in if they are hot they pant to cool down like dogs. Dingos and red foxes are some predators to kangaroos also the Tasmanian devil can be a threat to these animals. Kangaroos are herbivores so they eat grass and vegetation. Kangaroos extract the water from the vegetation the drink since there is not a lot of water in the savannas. Kangaroos are vertebrates since they have a back bone and also they are a mammal so that's why they are
