The Philippine tarsier (Carlito syrichta), is a species of tarsier endemic to the Philippines. It is found in the southeastern part of the archipelago, particularly on the islands of Bohol, Samar, Leyte and Mindanao. It is a member of the approximately 45-million-year-old family Tarsiidae, whose name is derived from its elongated "tarsus" or ankle bone. The Philippine tarsier has thin, rough fur which is colored gray to dark brown. The narrow tail, usually used for balance, is bald except for a tuft of hair at the end, and is about twice the body length.
