Know Your Primate grew out of posts I wrote specifically for the Friday Ark back on my old blog. The point was to write short, informative posts about whatever species struck my fancy (and at that point was not limited to primates).

In the time since I have focused on a wide variety of primates but, with one or two exceptions, have avoided the extant apes. This is largely due to the explosion of knowledge about them in the past 10-15 years, which makes it hard to write a short post in the format I have chosen for this series. Bearing that limitation in mind, here is this weeks primate.
