==Behavior==
[[Pygmy tarsier]]s differ from other species in terms of their morphology, communication, and behavior.<ref>{{cite journal |last1=Grow |first1=Nanda |last2=Gursky-Doyen |first2=Sharon |year=2010 |title=Preliminary Data On The Behavior, Ecology, And Morphology Of Pygmy Tarsiers ( Tarsius Pumilus) |journal=International Journal of Primatology |volume=31 |issue=6 |pages=1174–1191 |doi=10.1007/s10764-010-9456-9 |s2cid=23939646}}</ref> The differences in morphology that distinguish pygmy tarsiers from other species are likely based on their high altitude environment.<ref>{{cite journal |last1=Musser |first1=G.

All tarsier species are [[Nocturnality|nocturnal]] in their habits, but like many nocturnal organisms, some individuals may show more or less activity during the daytime. Based on the anatomy of all tarsiers, they are all adapted for leaping even though they all vary based on their species.<ref>{{cite journal |last1=Dagosto |first1=M. |last2=Gebo |first2=D.

Ecological variation is responsible for differences in morphology and behavior in tarsiers because different species become adapted to local conditions based on the level of altitude.<ref>{{cite journal |last1=Körner |first1=C |year=2007 |title=The use of 'altitude' in ecological research |journal=Trends in Ecology and Evolution |volume=22 |issue=11 |pages=569–574 |doi=10.1016/j.tree.2007.09.006 |pmid=17988759|bibcode=2007TEcoE..22..569K }}</ref> For example, the colder climate at higher elevations can influence cranial morphology.<ref>{{cite journal |last1=Rae |first1=T.

Tarsiers tend to be extremely shy animals and are sensitive to bright lights, loud noises, and physical contact. They have been reported to behave suicidally when stressed or kept in captivity.<ref>{{Cite news |last=Jarosz |first=Andy |date=20 May 2019 |title=The Philippines: The Tarsier Man |work=[[National Geographic]] |url=https://www.nationalgeographic.co.uk/travel/2019/05/philippines-tarsier-man |url-status=dead |access-date=28 September 2019 |archive-url=https://web.archive.org/web/20190521012214/https://www.nationalgeographic.co.uk/travel/2019/05/philippines-tarsier-man |archive-date=21 May 2019}}</ref><ref>{{Cite news |last=Sinclair |first=Joe |date=12 December 2011 |title=Tourism threatens tiny Philippine primate |work=My SinChew |publisher=[[Agence France-Presse|AFP]] |url=http://mysinchew.sinchew.com.my/node/67669 |url-status=dead |access-date=28 September 2019 |archive-url=https://web.archive.org/web/20190928114156/http://mysinchew.sinchew.com.my/node/67669 |archive-date=28 September 2019}}</ref>

===Predators===
Due to their small size, tarsiers are prey to various other animals. Tarsiers primarily inhabit the lower vegetation layers as they face threats from both terrestrial predators such as cats, lizards, and snakes, and aerial predators such as owls and birds. By residing in these lower layers, they can minimize their chances of being preyed upon by staying off the ground and yet still low enough to avoid birds of prey.

Tarsiers, though known as being shy and reclusive, are known to mob predators. In nature, [[Mobbing_(animal_behavior)|mobbing]] is the act of harassing predators to reduce the chance of being attacked. When predators are near, tarsiers will make a warning vocalization. Other tarsiers will respond to the call, and within a short period of time, 2-10 tarsiers will show up to mob the predator. The majority of the group consists of adult males, but there will occasionally be a female or two. While tarsier groups only contain one adult male, males from other territories will join in the mob event, meaning there are multiple alpha male tarsiers attacking the predator.<ref>{{cite journal |last1=Řeháková-Petrů |first1=M. |last2=Peške |first2=L. |date=2012 |title=Predation on a wild Philippine tarsier (Tarsius syrichta) |journal=Acta Ethologica |volume=15 |issue=2 |pages=217–220 |doi=10.1007/s10211-011-0096-7 |s2cid=254163428}}</ref><ref name="RefA" /><ref>{{Cite journal |last=Gursky |first=Sharon |date=February 2005 |title="Predator Mobbing in Tarsius Spectrum" |url=https://doi.org/10.1007/s10764-005-0731-0 |journal=International Journal of Primatology |volume=26 |issue=1 |pages=207–221 |doi=10.1007/s10764-005-0731-0 |s2cid=21188050 |via=EBSCOhost|url-access=subscription }}</ref>

===Diet===
Tarsiers are the only entirely [[Carnivore#Obligate carnivores|carnivorous]] [[Extant taxon|extant]] primates, albeit mainly [[insectivore|insectivorous]], catching invertebrates by jumping at them. The tarsiers also opportunistically prey on a variety of arboreal and small forest animals, including [[orthopterans]], [[scarab beetle]]s, small [[flying frogs]], [[lizards]] and, occasionally, amphibious [[crab]]s that climb into the lower sections of trees.<ref>{{Cite journal |last1=Crompton |first1=Robin Huw |last2=Blanchard |first2=Mary L. |last3=Coward |first3=Sam |last4=Alexander |first4=R.

===Reproduction===
[[Gestation]] takes about six months,<ref name="Izard et al., 1985">{{cite journal |last=Izard |first=Kay M. |author2=Wright, Simons |year=1985 |title=Gestation length in Tarsius bancanus |journal=Am J Primatol |volume=9 |issue=4 |pages=327–331 |doi=10.1002/ajp.1350090408 |pmid=31979510 |s2cid=83711759 }}</ref> 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. They reach sexual maturity by the end of their second year. Sociality and mating system varies, with tarsiers from Sulawesi living in small family groups, while Philippine and western tarsiers are reported to sleep and forage alone.
