5 Lesser-Known Facts About Tarsiers

Tarsiers are fascinating creatures known for their large eyes and unique behaviors. Here are five lesser-known facts about these small primates:

Nocturnal Predators

Tarsiers are nocturnal predators, primarily hunting for insects such as beetles, crickets, and grasshoppers under the cover of darkness. Their large eyes help them see well in low light conditions, making them efficient hunters in the dark.

Unique Communication

Tarsiers communicate through a variety of vocalizations, including ultrasonic calls that are beyond the range of human hearing. These calls are thought to play a crucial role in social interactions and locating one another in dense forests.

Unusual Diet

While insects make up the majority of their diet, tarsiers have been known to consume small birds, reptiles, and even bats on occasion. This diverse diet sets them apart from many other primate species.

Leaping Ability

Tarsiers are exceptional jumpers, capable of leaping distances of up to 5 meters (16 feet) between branches. Their long hind limbs and specialized ankle bones, which allow for greater flexibility, contribute to this impressive jumping ability.

Unique Anatomy

Tarsiers have several unique anatomical features, including their elongated tarsal bones, from which they derive their name. These bones help in their jumping prowess. Additionally, they have the largest eyes relative to body size of any mammal, each eyeball being as large as their entire brain.
