This is the "Slender Loris", found in southern Sri Lanka. The fossil record of the loris extends back to the Early Miocene (20 million years ago).
Populations of this small primate are declining because of deforestation, and conservationists plan to restore its habitat and establish corridors between fragmented areas of forest.
Also, it clearly is wiser than any of us, and as we've learned thoughout history, nobody likes a smartass.
The Slender Loris knows what you're thinking as you read this, and may very well be just under your desk, deciding wether to
a) crawl up your leg, or
b) watch you later from its perch on your slowly rising/falling chest as you sleep.
