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.
Dingoes probably arrived in Australia between 5,400 and 4,600 years ago, long after the first humans, spread rapidly across the continent and probably contributed to the extinction of even more native species such as the thylacine and Tasmanian devil.The current period of invasive species introduction began in 1788 with the arrival of the first ...
Native to the Mediterranean regions, more than one species of white snail is now quite common in Kadina and elsewhere in South Australia. This image shows many Theba pisana, and a number of smaller and more pointed Cochlicella acuta aestivating on a fence post. Cernuella virgata (Common white snail) [53] Cochlicella acuta (Pointed snail) [54]
The most species-rich group is Squamata, the snakes and lizards. They are especially diverse in the arid areas of Australia, where other fauna are scarcer. Spinifex grass is a major habitat which allows them to remain in a relatively cool, moist area. Australia has a large array of reptiles which can be dangerous to humans.
The Macropodiformes are divided into three families that are found in all Australian environments except alpine areas: the Hypsiprymnodontidae, with the musky rat-kangaroo as its only member; the Potoroidae, with 10 species; and the Macropodidae which had 53 members in Australia, but some species are extinct. The Potoroidae include the bettongs ...

This family of flightless ratite birds is represented by two living species in Australia. Another two species are found in New Guinea. The extinct, geographically isolated King and Kangaroo Island emus were historically considered to be separate species to mainland emus. However, genetic evidence from 2011 suggests that all three are conspecific.
