Australia is home to a diverse range of unique and fascinating animals, many of which are endemic to the continent due to its long geographic isolation. This isolation has resulted in the evolution of species particularly suited to Australia's harsh and dry environment, such as the kangaroo, koala, emu, and platypus. The country's fauna includes a high proportion of native marsupials, such as the Tasmanian devil and quokka, which occupy ecological niches typically filled by placental mammals in other parts of the world. Introduced species, habitat destruction, and hunting have led to numerous extinctions, and many of Australia's native species are now protected by legislation.

What You'll Learn
The koala, a tree-dwelling marsupial
Koalas have a large, round head with a wide, rounded nose, small eyes, and big furry ears. Their fur is typically grey-brown with patches of white fur on the chest, chin, neck, inner arms, ears, and rump. Male koalas have a brown scent gland on their chest, which they use to mark trees and deter other males from entering their home trees. Koalas have poor vision but excellent hearing and a strong sense of smell, which they use to detect predators and find food sources.
The diet of a koala consists primarily of eucalypt leaves and a few other tree species, including lophostemon, melaleuca, and corymbia. They consume a large quantity of leaves daily, which provides them with water and very little energy. As a result, koalas spend a significant amount of time resting and sleeping. Koalas are generally solitary animals, with a home range that includes more than a dozen trees. They are known to produce loud, hollow grunts and have distinct scratch marks on tree trunks due to their opposable digits and sharp claws.
Koalas have been classified as their own family, Phascolarctidae, due to their unique characteristics among marsupials. They have 11 pairs of ribs, the least of any recorded marsupial species, and a curved spine with a cartilaginous pad at the end, which may aid in their tree-dwelling lifestyle. Koalas have a small brain size in proportion to their body size and have distinctive fingerprints, similar to humans and primates.
In recent years, the status of koalas has changed from vulnerable to endangered, highlighting the importance of conservation efforts to protect this unique tree-dwelling marsupial native to Australia.

The kangaroo, a large hopping marsupial
The kangaroo is a large marsupial native to Australia, Tasmania, and nearby islands. It is a member of the animal family Macropus, which means "big foot". True to their name, kangaroos have large feet that allow them to leap up to 30 feet (9 meters) in a single bound and travel over 30 miles (48 kilometers) per hour. They are the tallest of all marsupials, standing over 6 feet tall.
Kangaroos possess powerful hind legs, a long and strong tail, and small front legs. They use their tails for balance while jumping. Their heads are relatively small, and their ears are generally large and rounded. Their mouths are small, with prominent lips. The pelage is usually soft and woolly, and stripes may be present on the head, back, or upper limbs.
Kangaroos are highly social and live in large groups called mobs, which can range from small herds to over a hundred individuals. They engage in nose touching and sniffing to build cohesion within the group. Boxing between males is used to establish dominance, with the dominant male leading the mob and having exclusive mating access to the females.
Female kangaroos have a pouch called a marsupium, which is made by a fold in the skin, to carry their young, known as joeys. Joeys are born after a month-long gestation period, blind, hairless, and under an inch in length. They crawl into the pouch, where they continue to develop and nurse for 120 to 400 days, depending on the species. Females produce two types of milk to cater to the different needs of newborn and more mature joeys.
Kangaroos are highly adaptable and can thrive in various habitats, including woods, bushland, grassland, savannas, forests, and scrubland. They are herbivores and occupy the ecological niche filled by grazing and browsing animals in other parts of the world.

The Tasmanian devil, with no natural predators
The Tasmanian devil, a carnivorous marsupial native to Australia, has no natural predators. It is the world's largest surviving carnivorous marsupial, characterised by its stocky and muscular build, black fur, pungent odour, extremely loud and disturbing screeches, and ferocity when feeding. The devil's large head and neck allow it to generate one of the strongest bites per unit body mass of any extant predatory land mammal. Its size is comparable to that of a small dog.
Tasmanian devils are known for their aggressive reputation, which is largely due to their threatening gape and fierce noises. However, these displays are often a result of fear rather than aggression. They are curious and energetic, travelling long distances at night in search of food. Devils are scavengers and will eat almost anything, including carrion. They also hunt live prey such as small mammals and birds. Despite being solitary creatures, they sometimes gather to feed on carcasses, resulting in the infamous growling and screeching that has earned them their name and reputation.
The Tasmanian devil was once present across mainland Australia but became extinct there around 3,500 years ago due to competition with the introduced dingo. They now inhabit the island state of Tasmania, where they are a keystone species in the ecosystem. Devils are protected under Tasmanian law and are considered an iconic symbol of the state. They find shelter during the day in dense bush, caves, bushes, old wombat burrows, or hollow logs within their habitat, which includes eucalyptus forests, woodlands, coastal scrubland, and agricultural areas.
The Tasmanian devil has been facing significant threats to its survival. Devil Facial Tumour Disease (DFTD) has drastically reduced their population, and they are now considered an endangered species. The Australian government has implemented the Save the Tasmanian Devil Program, sending devils to zoos worldwide as part of conservation efforts.

The platypus, one of the world's only egg-laying mammals
The platypus is one of the world's only egg-laying mammals. It is native to eastern Australia, including Tasmania, and is found in fresh water and estuaries. Platypuses are small, furry mammals with a distinct bill, webbed feet, and a wide beaver-like tail. They are one of the few venomous mammals, as the male platypus has a spur on its hind foot that delivers a painful venom.
The platypus has a unique appearance that initially baffled European naturalists. It has a bill and webbed feet like a duck, venom like a snake, and lays eggs like a reptile. This combination of features led early zoologists to question whether the platypus was a hoax, consisting of body parts from different animals sewn together. The platypus was first scientifically described in the 18th century by zoologist George Shaw, who also believed it to be a fake specimen.
As an egg-laying mammal, the platypus belongs to the group of monotremes, which are mammals that lay eggs instead of giving birth to live young. Monotremes are an evolutionary branch separate from marsupials and placental mammals. In addition to the platypus, there are four species of echidna, another monotreme that lays eggs. The platypus is the sole living representative of its family, Ornithorhynchidae, and its genus, Ornithorhynchus.
The platypus lays one to three small, leathery eggs, similar to those of reptiles. The eggs develop in utero for about 28 days, with only about 10 days of external incubation. The female platypus curls around the incubating eggs, which develop in three phases. In the first phase, the embryo has no functional organs and relies on the yolk sac for nourishment. In the second phase, the digits develop, and in the final phase, the egg tooth appears.
The platypus has ten sex chromosomes, compared to the two chromosomes typically found in other mammals. Its genome contains both reptilian and mammalian genes associated with egg fertilisation. The platypus's genes provide a possible evolutionary link between the mammalian XY and bird/reptile ZW sex-determination systems.

The dingo, a wild dog
Australia is home to a large variety of animals, with 46% of birds, 69% of mammals, 94% of amphibians, and 93% of reptiles that inhabit the continent being native to it. One of these native species is the dingo, a wild dog found exclusively in Australia, although absent from Tasmania. The dingo is descended from the New Guinea singing dog, which is considered a taxonomic synonym for the dingo by some mammalogists. The dingo has a long history of association with Indigenous Australians, with records of dogs associated with indigenous people dating back to 1623. The dingo is comfortable enough around humans to associate with them but is still capable of living independently.
The dingo's status as a domestic animal is unclear. While it exists in the wild and has not been selectively bred, it can be socialised to become an owned dog, and some dingoes live with human families. The dingo is proposed to have descended from early Asian dog breeds that arrived in Australia in two waves before the land bridge to Papua New Guinea was submerged 8,000 years ago. This isolation from other dogs until the arrival of European settlers resulted in the unique breed we know today.
The dingo is an apex predator and is very adaptable in its diet, consuming mammals as large as a red kangaroo, as well as birds, reptiles, frogs, crabs, insects, and even seeds. This has brought them into conflict with farmers, leading to the construction of the "dingo fence", a 5,500-kilometre barrier to exclude dingoes from the southeastern corner of the country. Despite this conflict, mounting research suggests that dingoes play an important role in maintaining ecological diversity, leading to calls for their protection.
The dingo goes by different names in various indigenous Australian languages, such as boolomo, dwer-da, joogoong, kal, kurpany, and more. The colonial settlers of New South Wales used the name "dingo" specifically for camp dogs, and it is believed that these camp dingoes only became wild after the colonial disruption of Aboriginal society. The dingo is an important part of Australia's fauna and has a complex relationship with both the environment and human populations.

Frequently asked questions
Many animals are native to Australia, including koalas, kangaroos, wombats, emus, dingoes, wallabies, platypuses, echidnas, kookaburras, quokkas, Tasmanian devils, and more.
Quokkas are small marsupials about the size of a house cat, with fluffy fur and rounded ears. They are part of the macropod family, which also includes kangaroos and wallabies, and they are mainly nocturnal herbivores. Quokkas are native to southwestern Australia and a few islands off the coast.
The Tasmanian devil is a native Australian animal that plays a crucial role in the ecosystem of Tasmania by performing natural pest control on introduced animals that threaten the state's native wildlife. They are now only found in Tasmania, but they were once seen throughout mainland Australia.
Dingoes are considered Australia's wild dogs and are the descendants of imported Indian wolves. They were brought to Australia by humans about 5,000 years ago and have since adapted to the challenging landscape of their adopted homeland.
Kookaburras are highly social and vocal members of the kingfisher family. They are native to eucalyptus forests but have adapted to modern life and can now be found across Australia. They are master hunters and mate for life.
