The Pygmy Tarsier is the smallest primate in the world, endemic to the Philippines and Indonesia. The tarsier was thought to be extinct in the early 20th century until 2008 when Dr. Sharon Gursky’s research team captured two males and a female. They were radio collared to track their movements.

The Pygmy Tarsier’s head – body measurement is about 10.16cm (4 inches) and it weighs less than 57g (2 ounces). Its tail measures 135-275mm (5 – 10 inches). The most unique feature of the tarsier is its large eyes about 16mm (0.6 inches) in diameter. Each eye is larger than the tarsier’s brain. Their eyes are so big that they are fixed to their skulls, however, their neck radius is 180 degrees. The tarsier’s name is derived from the extraordinarily long tarsus bones in their feet making their hands and feet twice as long as their bodies, giving them the ability to leap 40 times their body length.

Tarsiers are the only carnivorous primate feasting on insects, lizards and snakes, frogs, birds and bats. They eat no plant food whatsoever. The Pygmy Tarsier is usually found in monogamous pairs, remaining together for about 15 months. They have two breeding seasons, each producing one infant. The offspring are able to capture their own prey after only 42 days and travel in groups at 23 days.
