Question

What does one mean by region specific animals?

Answer 1

Geographically, a species or animal is restricted to a single location on the planet. They form in biologically isolated areas such as islands and large bodies of water, though hunting and habitat loss have pushed some continent-based animals to endemic status.

Complete answer:
The animals which can live only during a specific region are called region specific animals. Once, Gangetic dolphins, polar bears were region specific animals.
Fauna is all of the animal life present during a specific region or time. The corresponding term for plants is flora. Flora, fauna and other kinds of life like fungi are collectively mentioned as biota. Zoologists and paleontologists use fauna to invite a typical collection of animals found during a selected time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes invite a sequence of faunal stages, which can be a series of rocks all containing similar fossils. The study of animals of a selected region is known as faunistics.
Once common across Western Australia , the quokka is now listed as a species and is protected. However, they're still found in abundance on Rottnest Island, off the coast of Perth, and are a significant part of its tourist attraction.
The quokka can weigh up to 11 pounds and grow to 21 inches long. Although looking rather kind of a really small kangaroo, the agile critter can climb small trees and shrubs. They are fashionable tourists for his or her comical stocky build, rounded ears, and a quick , broad head. Unfortunately, there are numerous animal cruelty cases over the years, with perpetrators slapped with hefty fines.

Note:
The Australian region is one of the world's six major land areas, defined by its distinctive animal life. It includes Australia and the outlying islands of Tasmania, New Guinea, New Caledonia, New Zealand, Melanesia, Micronesia, and Polynesia, as well as Melanesia, Micronesia, and Polynesia.
