Thomas's Leaf Monkey, Gunung Leuser National Park, Sumatra, IndonesiaThe Thomas’s leaf monkey, also known as Thomas’s langur, is endemic to northern Sumatra (meaning, of course, that it isn’t found anywhere else on earth). I saw quite a few of these guys while there, but not many at close range. I was told that they were hunted for meat throughout much of their range, so obviously weary of humans (as they should be). In Gunung Leuser National Park, however, they are protected, so therefore a bit more agreeable. I liked their spiky hair and the fact that they seem to have an upside down mustache on their chin. Quite fetching I thought.
