Bohol Tarsier : Bohol Islands PhilippinesBohol Tarsier - Bohol Islands Philippines

The province is the home of the world's smallest monkey, the Tarsier. The size of a fist, the tarsier lives on hills of Corella, some ten kilometers from Tagbilaran. Other exotic flora and fauna can be found amongst the forest of Bohol. All year-round, the province's museums and churches attest to the province's rich heritage and culture.

Philippine Tarsier Foundation - Tagbilaran Bohol Philippines
Nonprofit organization dedicated to protecting the tarsier, a small primate with a round head and large owl-like eyes.

Philippine Tarsier: Tarsius syrichta

Suborder : Prosimii/Haplorrhini
Infraorder: Tarsiiformes
Superfamily: Tarsioidea

Taxonomy 3 subspecies

Distinguishing Characteristics
Philippine tarsiers have gray fur and a nearly naked tail. The middle finger is elongated.

Physical Characteristics

Head and Body Length: 124 mm (118-140) [4.9 in. (4.6-5.5)].
Tail Length: 232 mm [9.1 in.].
Weight: Female 117 gm [4.6 oz], Male 134 g [5.3 oz]
Intermembral Index: 58
Adult Brain Weight: 4 g [0.2 oz]. Males are larger than females.

Tarsiers have the highest infant-weight-to-maternal-weight ratio of any primate that gives birth to a single infant.

Habitat: Secondary lowland and coastal forest.

Diet: Animal prey (mostly insects; lizards).

Philippine tarsier in captivity will eat live shrimp and fish in a bowl of water.

Life History Weaning: 60d.
Sexual maturity: NA.
Estrus cycle: 23.5d.
Gestation: 180 d.
Age 1st Birth: NA.
Birth Interval: NA
Life span: 13.5y.
Mating: Year-round.
Offspring: 1

After copulation in captivity, vaginal plugs have been observed. The infant is born with open eyes and is carried by the female in her mouth when disturbed in captivity. The female parks her infant while foraging.

Locomotion Vertical clinging and leaping.

Social Structure

Groups are believed to be larger than 1 male and 1 female.

Group size: >2
Home Range: NA
Night Range: NA

Behavior Nocturnal and Arboreal.

Philippine tarsiers use hollows close to the ground for hiding. In captivity, individuals may huddle together or intertwine their tails. No male parental care has been observed. These tarsiers have intestinal parasites and external parasites such as Trichomonas.

Scent marking: Males have epigastric gland used for scent marking.
Vocalizations: The loud call is a loud piercing single note.

The contented call is a “soft sweet bird-like trill.” Several individuals make a “chirping locust-like communication." Females have a vocalization that signals their approaching sexual receptivity.

Tarsiers share some characteristics of both the prosimians and the anthropoids, while maintaining characteristics unique to themselves. Taxonomists have classified them as intermediate between both groups and have assigned them to their own infraorder, which has just one living genus - Tarsius. Their relatives in the fossil record are found going back to the Eocene epoch, from 54 to 36 million years ago.

Tarsiers are small, weighing only 113 - 142 grams (4 -5 ounces). Like many prosimians, they are nocturnal and have grooming claws and bicornuate uterus. Like anthropoids, they do not have a tapetum (a reflective layer in their eyes), and their eye sockets have postorbital closure rather than the postorbital bar of the prosimians. In tarsiers, the internal structures of the nose and ears and the blood supply to the brain and to a developing fetus are more like those of monkeys than of lorises. The monthly sexual swellings of female tarsiers are also similar to those in anthropoids.

Unique among primates, tarsiers have only 2, rather than 4, incisors in their lower jaw. Their dental formula is x 2 = 34.

Tarsiers are named for their special elongated tarsal bones, which form their ankles and enable them to leap 3 meters (almost 10 feet) from tree to tree. They have a long, partly hairless tail that arcs over their back when they hop on the ground.

The eyes are the tarsiers’ most notable features. Each eye is bigger than the entire brain. tarsiers can rotate their head almost 180 degrees in each direction, like owls. All tarsiers hunt at night, exclusively for animal prey. Their diet includes primarily insects
such as cockroaches and crickets and sometimes reptiles, birds, and bats. One tarsier species is found in the Philippines. Four species are currently recognized in Indonesia and another (Tarsius sangirensis) has been proposed, based on recently gathered field data on vocalizations, measurements, and genetics.

Philippine Cuisine Island Philippines

Philippine cuisine consists of the food, preparation methods and eating customs found in the Philippines. The style of cooking and the food associated with it have evolved over many centuries from its Austronesian origins to a mixed cuisine of Malay, Spanish, Chinese, and American, as well as other Asian and Latin influences adapted to indigenous ingredients and the local palate.
