Madagascan primates are a group of primates that are endemic to the island of Madagascar. The most well-known of these primates is the lemur, which is a small, arboreal primate with a long tail and a distinctive, fox-like face. Lemurs are the most diverse group of primates in Madagascar, with over 100 species identified. They are also the most threatened, with many species facing extinction due to habitat loss and hunting.
