The tarsier is one of the smallest primates in the world. They can only be as tall as 3.5 to 6.25 inches.   A highly endangered species endemic in parts of the Philippines and Indonesia, it has big eyes that provide acute night vision.   They are reputed too to be able to rotate their necks to almost 360 degrees.
