Top 10 Rarest Animals In The World

9) Addax: The Addax or white antelope is on the verge of extinction in its wild habitat of the Sahara Desert, with the size of the wild population ranging from 30 to 90 mature individuals. However, there are a number of successful breeding programs around the world, and while you most likely won't catch a glimpse of an Addax in the wild, you might just see one of the thousands in captivity at your local zoo. In the past, the Addax was common in North Africa, native to Chad, Mauritania, Niger, Algeria, Egypt, Libya, Sudan, and the Western Sahara. Wild Addax populations have been in severe decline due to unregulated hunting. In recent years, with the success of breeding programs, Addax have been reintroduced to Morocco and Tunisia on wildlife preserves.
