Tarsier

Tarsiers are prosimian primates of the genus Tarsius. Tarsiers have enormous eyes and long feet. Their feet have extremely elongated tarsus bones, which is how they got their name. They are primarily insectivorous, and catch insects by jumping at them. They are also known to prey on birds and snakes. As they jump from tree to tree, tarsiers can catch even birds in motion. Tarsiers have never formed successful breeding colonies in captivity, and when caged, tarsiers have been known to injure and even kill themselves because of the stress.

Big-eyed tarsiers: Tarsiers have remarkably large eyes, about 1.6cm. Each eye is bigger than the entire brain and larger than the stomach. So much so that they cannot move their eyes within the sockets. Instead, they special modifications to their neck vertebrae allowing them to rotate their heads nearly 360 degrees, even though they seem to have almost no neck! Unlike most other nocturnal creatures, however, tarsiers do not have a reflective layer behind the eyes (tapetum). They have excellent hearing, using their large funnel-like ears which are hairless, and thin and membranous. They can furl and unfurl their ears.
