Southern corroboree frog
It only lives in an area of about  in the Kosciusko National Park in south east Australia. Scientists believe that the total population of corroboree frogs is less than 250. Numbers of the frog have reduced by 80% in the last ten years, and so the International Union for Conservation of Nature and Natural Resources (IUCN) have listed the southern corroboree frog as being a critically endangered species.
