The Philippine Tarsier (Tarsius syrichta or Carlito syrichta), known locally as the Kupal in Cebuano/Visayan and Mamag in Luzon, is an endangered species of tarsier endemic to the Philippines. It measures only about 85 to 160 millimetres (3.35 to 6.30 in) in height, making it one of the smallest primates. The small size makes it difficult to spot. The mass for males is between 80–160 g (2.8–5.6 oz), usually lighter for females. The Philippine Tarsier's habitat is the second growth, secondary forest, and primary forest from sea level to 700 m (2,300 ft). Its habitat also includes tropical rainforest with dense vegetation and trees that offer it protection like tall grasses, bushes and bamboo shoots. Its diet consists of live insects and it has also been observed to feed on spiders, small crustaceans, and small vertebrates such as small lizards and birds.
