What is the most Endangered species of frog?
To answer that you have to think about what endangered means. Is it the frog species with the smallest number of individuals? Or is it the frog species in which the number of individuals is being reduced the most quickly? Either way you ask the question, for most species we don’t have the numbers to actually say which is the most endangered. But we do know that many kinds of frogs have been reduced to a very small number of individuals and many frogs have numbers which appear to be declining rapidly. For example, the Ramsey Canyon Leopard Frog Rana subaquavocalis in the United States is known from only about 100 individuals and Hamilton ‘s Frog Leiopelmahamiltoni from a small island in New Zealand appears to consist of only about 300 individuals. In general, the more restricted a species habitat is, the more endangered it is likely to be. That is why is so important to save habitats and not just keep rare frogs breeding in zoos.
