Which country is home to the platypus, kangaroo, dingo, and koala?

The platypus, kangaroo, dingo, and koala are all native to Australia, making it the correct answer. Australia is renowned for its unique wildlife, much of which is endemic, meaning these species are found nowhere else in the world. The continental isolation of Australia has allowed for the evolution of these distinctive animals in ways that differ from their counterparts on other continents.

For instance, the platypus is a monotreme, an egg-laying mammal with a duck-bill, which is a unique feature among mammals. The kangaroo is known for its powerful hind legs and is a symbol of Australia, representing its unique ecosystem. The dingo, a wild dog, is integral to Indigenous Australian culture and ecology. Lastly, the koala, known for its tree-dwelling habits and dependence on eucalyptus leaves, exemplifies the diversity of marsupials found in Australia. Together, these animals illustrate the rich biodiversity of the Australian continent, highlighting its significance as a habitat for such specialized wildlife.
