Tarsier
Behavior

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 likely based on their high altitude environment.

All tarsier species are 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.

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. For example, the colder climate at higher elevations can influence cranial morphology.

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.
