Tarsier

With their big eyes and curious ears, tarsiers might be the closest thing to a real-life mogwai. Found on the islands of Southeast Asia, these fluffy arboreal creatures are believed to be the last living examples of an ancient branch on the evolutionary tree of primates. In other words, they're relatively close cousins to us.

Their large eyes are an adaptation to being nocturnal. Their batlike ears also help them to navigate in the dark, and they use both these skills to track down their favorite food: insects. In fact, tarsiers are the only extant primates that are entirely carnivorous. They're also known to feast on small birds, lizards and even bats!
