Why is it important to protect endemic animals?
Endemic species are important for a number of reasons. First, since endemic species have a generally restricted distribution, threats to endemics carry more risk of extinction than for broadly distributed species. Thus, endemic species are a focus for the conservation of biological diversity, or biodiversity.
