Tarsier

Although the tarsier was once more widespread, all the species living today can be found only on the islands of Southeast Asia.

Tarsiers are small animals with huge eyes; each eyeball is approximately 16mm in diameter and is as large as its brain.  They also have strong auditory sense because of their distinct auditory cortex.

Food: they are mostly insectivorous, though they also prey on birds, snake, lizards and bats.

Habitat: islands on Southeast Asia
