An endangered species is a species whose population is so small that it is in danger of becoming extinct. Many countries have laws offering special protection to these species (forbidding hunting, banning development, etc. of their habitats) to prevent their extinction. Only a few of the many truly endangered species actually make it to the lists and obtain legal protection. Many more species become extinct, or potentially will become extinct, without gaining public notice.
Sometimes a listing as an endangered species can backfire, as it makes a species more valuable and more desirable for collectors and poachers.
There are approximately 18 frogs listed as endangered in Australia.
