The animal on the cover of HTML and XHTML: The Definitive Guide, Fifth Edition is a koala. The koala is an Australian marsupial, the only member of the Phascolarctidae family.

When they are born, koalas are tiny, weighing approximately 0.5 grams. A young koala stays in its mother's pouch for approximately seven months. Unlike most marsupials, the koala's pouch opens near the rear, not near the head. Koalas have a high mortality rate and face extinction in Australia due to epidemics in 1887-1889 and 1900-1903 and unrestrained hunting throughout the 20th century. They are a protected species. Populations are rebuilding, but at present, they survive only in eastern Australia.
