Meet the Quokka Happiest Animal on Earth Rottnest Island Western Australia
Quokkas eat many types of vegetation, including grasses and leaves. Quokkas has little fear of humans and quokkas commonly approach people closely, particularly on Rottnest Island, where a prevalent population exists. Though quokka smiling has a reputation of being the happiest animal on Earth, annually, a few dozen cases of quokkas biting people, especially children, are reported. Quokkas behaviour in response to human interaction has been examined in zoo environments. One brief study indicated fewer animals remained visible from the visitor paths when the enclosure was an open or walk-through environment.
