ruffed lemur

In the wild, ruffed lemurs live in only one place—the eastern rain forests of Madagascar. Lemurs are prosimians, which means they belong to a group of primates that existed for millions of years, long before monkeys, apes, or humans appeared. Lemurs are endangered because their habitat is being destroyed and also because people hunt them for food.
