The Tarsier is an adorable primate found in the islands of Southeast Asia. Their name comes from the elongated tarsus bones in their hind legs. The most fascinating things about this small animal lies in its eyes. A single eye is roughly 16 mm in diameter and is the size of their brain. As a nocturnal animal, the large eye surface is great in terms of letting in light. Unlike other nocturnal animals, they lack the shiny tapetum lucidum (found in animals like dogs and sheep) that lies in the back of the eye and reflects light. The wiring of the tarsier brain is also different from other primates in terms of connections between the two eyes and the regions that assess visual data. Here you can see the skull and large eye sockets of a tarsier:
