One way in which Australian animals have adjusted to the presence of the cane toad is through learned behavioural adaptations. [5] [7] [8] These phenotypically plastic behavioural modifications are usually induced by conditioned taste aversion.
The red kangaroo is the largest extant macropod and is one of Australia's heraldic animals, appearing with the emu on the coat of arms of Australia. [1]The fauna of Australia consists of a large variety of animals; some 46% of birds, 69% of mammals, 94% of amphibians, and 93% of reptiles that inhabit the continent are endemic to it.
The mammals of Australia have a rich fossil history, as well as a variety of extant mammalian species, dominated by the marsupials, but also including monotremes and placentals. The marsupials evolved to fill specific ecological niches, and in many cases they are physically similar to the placental mammals in Eurasia and North America that ...
The large kangaroos have adapted much better than the smaller macropods to land clearing for pastoral agriculture and habitat changes brought to the Australian landscape by humans. Many of the smaller species are rare and endangered, while kangaroos are relatively plentiful, despite a common misconception to the contrary.
Two species of tree-kangaroos are found in Australia, Bennett's (D. bennetianus), which is found north of the Daintree River and Lumholtz's (D. lumholtzi). Tree-kangaroos have adapted better to regions of high altitudes. [17] Tree-kangaroos must find places comfortable and well-adapted for breeding, as they only give birth to one joey per year.

The spread of the cane toads in Australia from 1940 to 1980 in five-year intervals. The long-term effects of toads on the Australian environment are difficult to determine, but some effects include "the depletion of native species that die eating cane toads; the poisoning of pets and humans; depletion of native fauna preyed on by cane toads; and reduced prey populations for native insectivores ...
Although at this time South America, Antarctica and Australia were still joined the order evolved in Australia for at least 40-50 million years. The Riversleigh fossil material suggests that Notoryctes was already well adapted for burrowing and probably lived in the rainforest that covered much of Australia at that time.
