Encompassing 287 hectares (710 acres), the Toronto Zoo is the largest zoo in Canada. It is divided into seven zoogeographic regions: Indo-Malaya, Africa, Americas, Tundra Trek, Australasia, Eurasia, and the Canadian Domain. Some animals are displayed indoors in tropical pavilions and outdoors in what would be their naturalistic environments, with viewing at many levels. It also has areas such as the Kids Zoo, Waterside Theatre, and Splash Island. It has one of the most taxonomically diverse collection of animals on display of any zoo; it is currently home to over 5,000 animals (including invertebrates and fish) representing over 500 species.
