Koala, Hanson Bay, Kangaroo Island, South AustraliaA koala takes a good yawn in-between bites of eucalyptus leaves on Kangaroo Island in Southern Australia. Eucalyptus is, of course, all that a koala eats, making the species very vulnerable as eucalyptus forests get more and more fragmented across southern and eastern Australia.
