Tarsier

The most specialized of the group is a wan little Malayan creature about the size of a small rat, with a long tail, long hind legs, and toes ending in pads that enable the tarsier, or "malmag," as it is called, to climb the smoothest bamboo. Its eyes are so big they seem to leave no room for cheeks. Even more curious is the aye-aye of Madagascar, which resembles a small squirrel with a terrier's face; its hind feet are like a monkey's hand, and its forefeet are composed of very long naked fingers armed with sharp claws useful in pulling bugs and grubs out of crevices in bark, or the pulp out of fruits.
