Want to know which animal is the happiest ever? Easily, quokkas – they smile better than most humans. The quokka was one of the first Australian mammals seen by Europeans.
The quokka is the only member of the genus Setonix, a small macropod about the size of a domestic cat.
Like other marsupials in the macropod family (such as the kangaroos and wallabies), the quokka is herbivorous and mainly nocturnal. It can be found on some smaller islands off the coast of Western Australia, in particular on Rottnest Island just off Perth and Bald Island near Albany.
The quokka has no fear of humans and it is common for it to approach them closely, particularly on Rottnest Island.
