Tarsiers have some of the largest eyes relative to their body size of any animal. This comes at a cost, however — they cannot rotate their eyeballs within the sockets but must rotate their entire heads instead. The Philippine tarsier, Carlito syrichta, lives only on a handful of islands in the Philippines. See where the other species live.
