Roger Federer loves quokkas. I can see why and why a lot of other people like them too. The cuteness factor is high. This is a high quality photograph too; smiling, happy and animated against a serene background.
Quokkas are known for their smile 🙂 . It looks like that because people search for smiling quokkas. They are short-tailed wallabies. They are about the size of a domestic cat. They belong to the family of animals called macropods. Other members of that family are kangaroos and wallabies. They are found on islands off the southwestern corner of the continent of Australia e.g. Rottnest Island off Perth. They weight between 5.5 and 11 pounds. They have evolved to be partly arboreal (tree dwellers). They climb trees up to about 5 feet in height. They live for about ten years and are nocturnal. When sleeping they use the protection of the spikes of the Acanthocarpus preissii plant. It is believed that their name quokka is derived from a Nyungar word ‘gwaga’
