Indo-Australian Realm

The Indo-Australian Realm is a major biogeographic zone that includes Australia, the Indian subcontinent, and surrounding islands. It features diverse ecosystems like deserts, rainforests, and savannas. This realm is characterized by a unique mix of flora and fauna, such as kangaroos, koalas, and various tropical plants, many of which are adapted to its specific climates. Its isolation has led to high levels of endemism, meaning many species are found nowhere else. The realm's geological history and climate diversity make it one of the most distinctive biological regions globally.
