The Philippine Tarsier
The Philippine Tarsier (Tarsius syrichta or Carlito syrichta), known locally as the Maumag in Cebuano/Visayan and Mamag in Luzon, is an endangered species of tarsier endemic to the Philippines. It is found in the southeastern part of the archipelago, particularly in the islands of Bohol Island, Samar Island, Leyte Island 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.
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 eyes are disproportionately large, having the largest eye-to-body size ratio of all mammals. These huge eyes provide this nocturnal animal with excellent night vision. The large membranous ears are mobile, appearing to be almost constantly moving, allowing the tarsier to hear any movement.The Philippine Tarsier has thin, rough fur which is colored gray to dark brown. The narrow tail, usually used for balance, is naked or bald except for a tuft of hair at the end, and is about twice the body length. Its elongated "tarsus," or ankle bone, which gives the tarsier its name, allows it to jump at least three meters from tree to tree without having to touch the ground. Its long digits are tipped with rounded pads that allow T. syrichta to cling easily to trees and to grip almost any surface. The thumb is not truly opposable, but the first toe is. All of the digits have flattened nails, except for the second and third toes, which have sharp claws specialized for grooming.
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. It prefers dense, low-level vegetation in secondary forests, with perching sites averaging 2 meters above the ground.

Please avoid visiting the tarsiers kept in cages along Loboc river. Here, these shy animals have a miserable live, and normally don't survive for long.

It is a member of the approximately 45 million year old family Tarsiidae, whose name is derived from its elongated "tarsus" or ankle bone.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.
It was only introduced to Western biologists in the 18th century.
Anatomy and morphology
The Philippine Tarsier is not a large animal; 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, somewhat heavier than otherTarsius 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.

The Philippine Tarsier, as its name suggests, is endemic to the Philippine archipelago. T. syrichta populations are generally found in the southeastern part of the archipelago. Established populations are present primarily on the islands of Bohol, Samar, Leyte and Mindanao. It has also been found on various isolated islands within its known range, such as Maripipi Island, Siargao Island, Basilan Island and Dinagat Island.
Habitat
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. It prefers dense, low-level vegetation in secondary forests, with perching sites averaging 2 meters above the ground.Ecosystem roles
Besides human hunters, feral cats banished from nearby communities are the species' main predators, though some large birds are known to prey on it as well. Because of its nocturnal and arboreal habits, the Philippine Tarsier is most likely to fall prey to owls, or to small carnivores which it can encounter in its canopy homes.
Communication
The Philippine Tarsier uses varied means of communication. Although less vocal than many primate species, it uses calls which are often associated with territorial maintenance and male-female spacing. Its "loud call" is a loud piercing single note. When content, it emits a sound similar to a soft sweet bird-like twill. And when several tarsiers come together, they have a chirping, locust-like sound.
Its vocal communication is the distress call made by infants when they are separated from their mothers. It is also the call made by males to their mates during mating season. Its olfactory communication is the marking of a scent from the circumoral gland which the female uses to mark her mate with the gland located around the mouth. It is also the marking of a male's territory with the use of urine. Its tactile communication is the social grooming done when one tarsier grooms the other, removing dead skin and parasites, observed in females on adult males, as well as in females on their offspring.
