Second Smallest 

Species of Primate In the World

Tarsiers are the second smallest species of primate in the world (second only to the marmoset.)

Their bodies are small and delicate, with long, slender fingers and toes and soft, fuzzy fur.

Physical Traits

Their eyes are so large that they cannot move them within their sockets – instead, they rely on their long, flexible necks to look around.

Tarsiers reside in a variety of habitats, from primary rainforest to secondary growth and even human settlements.


They are most commonly found in Indonesia, Malaysia, and the Philippines.

As nocturnal hunters, tarsiers feed mainly on insects like grasshoppers, beetles, and moths.


They stalk their targets before leaping on them with their powerful hind legs.

Despite their small size, tarsiers are incredibly agile and can jump distances of up to 40 times their body length in a single bound.


Tarsiers communicate with a range of vocalizations, including danger calls, territorial calls, and mating calls, among others.

They have complex inner ear structures that enable them to detect and locate high-frequency sounds beyond the range of human hearing.


Females carry their offspring for approximately six months, one of the longest gestation periods among primates relative to their body size.

Additionally, tarsiers typically give birth to single or twin offspring, which are relatively large compared to the mother’s size.

Conservation Status

Deforestation, land development, and mining have destroyed many tarsiers’ natural habitats.

Threats include habitat loss, illegal hunting, and illegal pet trade.

All of these threats have caused a severe decline in tarsiers’ populations, putting them on the IUCN Red List of Threatened Species.
