Thanks WikipediaThe Philippine Tarsier is a tiny animal, measuring about 4 to 6 inches (15 cm) in height. The small size makes it difficult to spot. The average mass for males is around 134 grams, and for females, around 117 grams. The average adult is about the size of a human fist and will fit very comfortably in the human hand.
Like all tarsiers, the Philippine Tarsier's eyes are fixed in its skull; they cannot turn in their sockets. Instead, a special adaptation in the neck allows its round head to be rotated 180 degrees. The large membranous ears are mobile,[7] appearing to be almost constantly moving, allowing the tarsier to hear any movement. It has uniquely large eyes (disproportionate to its head and body), which are listed in the Guinness Book of Records as the largest eyes on any mammal. These huge eyes provide this nocturnal animal with excellent night vision.[8]
For the past 45 million years, tarsiers have inhabited rainforests around the world, but now they only exist on a few islands in the Philippines, Borneo and Indonesia.[5] In Bohol, the Philippine Tarsier was a common sight in the southern part of the island until the 1960s. Since then, the number has dwindled to as few as an estimated 1000 still left in the wild.[citation needed] Once protected by the humid rainforests and mist-shrouded hills, these mysterious primates struggle to survive as their home is cleared for crop growing.
