Kangaroo is one of the most recognised animals in the world, even though present only in Australia and nearby islands.  Pademelons, Wallabies, Wallaroos and Kangaroos look very much the same in body structure but the distinct name is given based on their sizes. Originally Pademelons were called small wallabies and wallabies were called large wallabies. But a more suitable name was needed to differentiate them. Young ones of these groups are known as “joeys”, like many other marsupials. Adult male are referred to as “bucks”, “boomers”, or “jacks”. An adult female is known as a “doe”, “flyer”, or “jill”. A group of these animals are called a “court”, “mob”, or “troup”
