书名：RESTful Web Services（影印版）
The animal on the cover of RESTful Web Services is a vulpine phalanger (P. vulpina).
Phalanger is the general term given to animals of the Phalangeridae family, which includes possums and cuscuses. (One should not confuse the Australian possum with the American opossum; they are both marsupials, but very different.) The term phalanger is derived from the Greek word phalanges, which means finger or toe bone. The omnivorous phalanger uses its claw-fingered paws (with opposable thumbs) to climb,hunt, and live in trees. Phalangers are found in the forests of Australia, New Zealand,Tasmania, and some Indonesian islands. Like the most famous marsupial, the kangaroo,female phalangers carry their young around in a front pouch after birth.
Phalanger is also the name of a PHP complier project for the .NET framework.
