Tarsier, the world's smallest monkey, has large eyes (big as their brain), a long tail and ears with almost no hair. It is a carnivores animal that feeds on insects and can move its ears to determine the location of the prey. Its flexible neck can turn up to 180 degrees. They can't walk so they hop when they on ground and mark their trees with their urine. Interesting fact is that they are something in between a monkey and a primate.
