8. Madame Berthe’s Mouse Lemur (Microcebus berthae)
Madame Berthe’s mouse lemur is the tiniest primate in the entire world. Like all lemurs, they live in Madagascar; these mouse lemurs live in only one region, Kirindy Mitea National Park. They are a mere 3.6 inches (92 millimeters) long, with an average weight of 1.1 ounce (30 grams). The species is named after Madagascar’s famous conservationist Madame Berthe Rakotosamimanana.
