Macropus is a genus of marsupials that includes kangaroos and wallabies, native to Australia and New Guinea. These animals are known for their powerful hind legs, which allow them to hop efficiently across vast distances. They have long tails that help with balance and are typically herbivorous, feeding on grasses and leaves. Kangaroos, the largest members of the Macropus genus, can reach heights of over six feet. Wallabies, on the other hand, are smaller and often found in forested areas. Both types of animals play a significant role in their ecosystems, contributing to seed dispersal and maintaining vegetation health.
