Information: - New Zealand is an island nation in the southwestern Pacific Ocean. The country geographically comprises two main landmassesthat of the North Island, or Te Ika-a-Mui, and the South Island, or Te Waipounamuand numerous smaller islands. New Zealand is situated some east of Australia across the Tasman Sea and roughly south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. During its long period of isolation, New Zealand developed a distinct biodiversity of animal, fungal and plant life. The country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volcanic eruptions. New Zealand's capital city is Wellington, while its most populous city is Auckland. - The Archaeobatrachia are a suborder of Anura containing various primitive frogs and toads. As the name literally suggests, these are the most primitive frogs. Many of the species (28 in total) show certain physiological characteristics which are not present in other frogs and toads, thus giving rise to this group. They are largely found in Eurasia, New Zealand, the Philippines, and Borneo, and are characteristically small. In addition, the family Ascaphidae is found in the Pacific Northwest and northern rocky mountains of the United States, and is only represented by two species. - Toad is a common name applied to certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and parotoid glands. - Auckland is a city in the North Island of New Zealand.

The leiopelmatids ' relatively primitive form indicates they have an ancient lineage . While some taxonomists have suggested combining the North American frogs of the genus Ascaphus in the family Ascaphidae with the New Zealand frogs of the genus Leiopelma in the Leiopelmatidae family , the current consensus is that these two groups constitute two separate families . The four extant species of Leiopelmatidae are only found in New Zealand . - Tonga (or ; Tongan: "Puleanga Fakatui o Tonga"), officially the Kingdom of Tonga, is a Polynesian sovereign state and archipelago comprising 169 islands of which 36 are inhabited.

Though no agreed boundary exists, a common conception includes the U.S. states of Oregon and Washington and the Canadian province of British Columbia. Broader conceptions reach north into Alaska and Yukon, south into far northern California and east to the Continental Divide, thus including Idaho, Western Montana, and western Wyoming. Narrower conceptions may be limited to the northwestern US or to the coastal areas west of the Cascade and Coast mountains. The variety of definitions can be attributed to partially overlapping commonalities of the region's history, geography, society, and other factors. - Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. Australia's capital is Canberra, and its largest urban area is Sydney.
