A marsupial is a type of animal characterized by giving birth to relatively undeveloped young, which then typically continue to grow and develop in a pouch on the mother’s body. Marsupials are primarily found in Australia and nearby islands, with the most well-known example being the kangaroo. Other members of this group include koalas, wallabies, and opossums. They have distinctive reproductive systems that differentiate them from placental mammals. Marsupials play a vital role in their ecosystems and exhibit a range of adaptations to various habitats, showcasing their diversity in both form and ecological niche.
