Kangaroos are large marsupials native to Australia. They are known for their powerful hind legs, which allow them to hop at high speeds and cover long distances. With their strong tails, kangaroos can balance while standing and even use them for support when sitting. They are herbivores, primarily eating grass and leaves. These unique animals live in groups called mobs, which provide safety in numbers. Kangaroos are also famous for their pouches, where female kangaroos carry and nurture their young, called joeys. This fascinating reproductive trait is a key characteristic of marsupials, a group that includes other animals like koalas and wombats.
