There are . Catchpole, H., J. Fulton. Baby tarsiers are born with fur and are able to climb within a day of birth! They have eyes that are heavier than their brains. Determinants of gregariousness in the spectral tarsier(Prosimian: Tarsius spectrum). With eyes twice as big as their brains, a head that can rotate 180 degrees in each direction and the ability to track prey using ultrasound, the tiny animals are formidable nocturnal hunters. That's why they bump their heads on the cage, and it will crack because the cranium is so thin, the Tarsier Man tells AFP. Tarsiers are the only exclusively carnivorous primate; they eat insects, small birds, rodents and lizards. These genes likely are linked to the tarsiers unusual traits. Eye size and visual cortex of the Tarsier animal are probably required by the absence of the reflex layer (tapetum) that most other nocturnal mammals have in their eyes. These arboreal primates are found in forests that range in density and agriculture from island to island. The fossil record of tarsiers dates to between 34 and 56 million years ago, in the Eocene era (Zijlstra, 2013). These huge eyes allow for nocturnal vision, despite the lack of a tapidum lucidum.

Home ranges, spatial movements and habitat associations ofthe Philippine tarsier (Tarsius syrichta) in Corella, Bohol. None of these explain the snake-like movements (an extra vertebrate in their spine gives lorises this ability), hiss and markings, but they certainly could have sped along the evolution of a poisonous bite. Tarsiers are lemurlike in being nocturnal and having a well-developed sense of smell. A new study shows that these tree-dwellers emit squeaky calls well above the vocal range of any known monkey or ape, perhaps to dodge eavesdropping predators.
