Australia is home to a diverse range of wildlife, known for its unique and often endemic species. The continent's isolation has led to the evolution of animals such as the kangaroo, koala, and platypus, which are not found naturally anywhere else in the world. Australia also boasts a variety of reptiles, birds, and marine life, including the great white shark and bottlenose dolphin. The country's varied ecosystems, from deserts to rainforests, support this rich biodiversity. Many species, like the emu and Tasmanian devil, play crucial roles in their habitats. However, habitat loss and invasive species pose significant threats to Australia's fauna, making conservation efforts essential.
