Despite sharing some traits with strepsirrhines (the lemurs and lorises), tarsiers are actually a sister group to anthropoids, the group that encompasses monkeys and apes, including humans.
Why are tarsiers suicidal?
Because the tarsier is often shy and nervous, many activities associated with captivity (such as camera flashes, being touched, and being kept in an enclosure) stresses the animal. Such stress leads to the tarsier hitting its head against objects, thus killing it because of its thin skull.

How long does it take for a tarsier to give birth?
For example, the colder climate at higher elevations can influence cranial morphology. Gestation takes about six months, and tarsiers give birth to single offspring. Young tarsiers are born furred, and with open eyes, and are able to climb within a day of birth.
What are tarsiers prey to?
Due to their small size, tarsiers are prey to snakes, owls, lizards, and cats. When a predator is present the tarsiers surround the threat vocalizing and attacking it. While tarsier groups only contain one male, when confronting a threat other groups will join, meaning there are multiple alpha male tarsiers attacking.
How big is a tarsier?
Tarsiers are quite similar, physically. They are all very small, with the largest being only a foot and a half from its head to the tip of its tail. Their tails are very long, and can be twice their body length. So, in a one and a half foot tarsier, the tail would make up one whole foot of that length!

Despite the different species contained within this group, tarsiers share a number of characteristics. For example, they are all found in Southeast Asia and, of course, they all have long ankle bones.
Do tarsiers have the same genus?
Tarsiers share more than just a genus . There are several different levels of taxonomy, or scientific classification, for any species or group. Taxonomy starts with the largest category (kingdom,) and goes down to the smallest main category (species.) All tarsiers have the same taxonomy for every category above 'Species.'
Where are tarsiers found?
The Tarsier is a small species of primate that is found inhabiting the well-vegetated forests on a number of islands in south-east Asia. Although fossil records show that Tarsiers are animals that would have once been found in mainland Asia, Europe, North America and in Africa, modern Tarsiers are today restricted to just a handful of islands in Malaysia, Indonesia and the southern Philippines. Despite constant debate amongst scientists over the naming and classification of Tarsier species, in 2011 there were 18 different sub-species of Tarsier described that are split into three groups generally depending on their geographic location, which are Western Tarsiers, Eastern Tarsiers and Philippine Tarsiers. Although science is slowly discovering more and more about Tarsiers in the wild, data can be hard to collect due to their shy and elusive nature and coupled with the constant confusion over the classification of separate species, makes conservation efforts difficult.

Why are tarsiers endangered?
Although conservation work particularly of the Philippine Tarsier is striving to protect these animals and their remaining pockets of primary forest, they remain threatened by loss of habitat throughout much of their natural range. Captive breeding programmes are quite unsuccessful as only around 50% of Tarsiers captured are said to survive in their new homes generally due to a lack of live food and there is also a high infant mortality rate along with a slow reproduction rate of individuals kept in zoos.
How do Tarsiers look?
The Tarsier is a unique and distinctive looking animal that has evolved a number of specific features to aid its nocturnal and arboreal lifestyle. Although the exact appearance of the Tarsier may vary slightly between species, all are relatively similar with a small, stocky body and long tail that is either sparsely covered in fur or has a tuft at the end. Their immensely soft fur varies from grey, to brown or ochre in colour depending on the species, but all Tarsiers share the characteristic long hind legs which enable them to leap distances of up to 5 meters between branches. The long fingers and toes of the Tarsier are tipped with pads and have nails to help them grip onto branches and prey, with long, curved claws on their second and third digits which are used for grooming. The most distinctive features of the Tarsier though can be found on their heads which (thanks to specially adapted vertebrae) are able to turn 180 degrees in both directions so that this primate can see behind it without moving its body. Their enormous eyes can be up to 16mm across and enable the Tarsier to hunt for prey and watch out for predators in the dark. Tarsiers also have large bat-like ears which are incredibly sensitive to detect even the slightest sounds close-by.

How long does it take for a tarsier to reproduce?
Reproduction of the Tarsier. Tarsiers become sexually mature at about 1-2 years of age, and tend to breed all year round. Once mated, the female has a pregnancy (gestation) lasting approximately 180 days (6 months), after which she usually gives birth to just a single baby.
Why are tarsiers so shy?
Because of the shy nature of tarsiers, there is often limited information about their distribution and the effects of human interactions. Forest clearance occurs in much of their natural range for plantation of such things as palm oil trees. Additionally, mining and land clearance have forced the tarsier from its habitats. It is thought that the general population is drastically declining, due to habitat loss and fragmentation of breeding populations. These land-clearing activities have an especially negative effect on small or unique island ecosystems. Tarsiers are also often captured for the exotic pet trade, or trapped for eating.
Why do tarsiers have long legs?
Their fur is very soft and the color varies from gray to brown, or reddish-brown. All tarsiers have long hind legs to help them move about in the trees they inhabit. These long legs are due mainly to elongation of bones in an area of the foot called the tarsus – hence the animals’ name.

Overview
Tarsiers are haplorhine primates of the family Tarsiidae, which is itself the lone extant family within the infraorder Tarsiiformes. Although the group was once more widespread, all of its species living today are found in Maritime Southeast Asia, specifically the Philippines, Malaysia, Indonesia, and Brunei.
They are found primarily in forested habitats, especially forests that have liana, …
Evolutionary history
Fossils of tarsiiform primates are found in Asia, Europe, and North America, with disputed fossils from Africa, but extant tarsiers are restricted to several Southeast Asian islands in Indonesia, Philippines, and Malaysia. The fossil record indicates that their dentition has not changed much, except in size, in the past 45 million years.
Anatomy and physiology
Tarsiers are small animals with enormous eyes; each eyeball is approximately 16 millimetres (0.63 in) in diameter and is as large as, or in some cases larger than, its entire brain. The unique cranial anatomy of the tarsier results from the need to balance their large eyes and heavy head so they are able to wait silently for nutritious prey. Tarsiers have a strong auditory sense, and their auditory co…
Behavior
Tarsiers are the only extant entirely carnivorous primates: they are primarily insectivorous, and catch insects by jumping at them. Their favorite prey are arthropods like beetles, spiders, cockroaches, grasshoppers, and walking sticks. They are also known to prey on birds, snakes, lizards, and bats.
Pygmy tarsiers differ from other species in terms of their morphology, communication, and behavior. The differences in morphology that distinguish pygmy tarsiers from other species are l…
Conservation
Tarsiers have never formed successful breeding colonies in captivity. This may be due in part to their special feeding requirements.
