Aye-aye is a lemur, a strepsirrhine primate native to Madagascar that combines rodent-like teeth that perpetually grow and a special thin middle finger. It is the world's largest nocturnal primate. A bit scary but I find it cute!
Known as Griffin's Leaf Nosed bat, it was discovered in Vietnam by mammalogist Du Vinh Thong and his team. The creature's weird nose shape is to help with echolocation. Its official name is Hipposideros griffini.
