the philippine tarsier at bohol

The Philippine Tarsier (Tarsius syrichta), known locally as the Maumag in Cebuano/Visayan, is an endangered tarsier species endemic to the Philippines. It is found in the southeastern part of the archipelago, particularly in the islands of Bohol, Samar, Leyte, and Mindanao. Its name is derived from its elongated "tarsus" or ankle bone.

The Philippine Tarsier is a tiny animal, measuring about 85 to 160 millimetres (3.35 to 6.30 in) in height makes this one of the smallest primates. The small size makes it difficult to spot. The mass for males is between 80 and 160 grams, usually lighter for females, somewhat heavier than other Tarsius such as the Pygmy tarsier. The average adult is about the size of a human fist and will fit very comfortably in the human hand.

Its geographic range also includes Maripipi Island, Siargao Island, Basilan Island and Dinagat Island. Tarsiers have also been reported in Sarangani, although they may be different subspecies. Being a member of a family that is about 45 million years old, it was only introduced to western biologists in the 18th century.
