Gray-Shanked Douc

Scientists first discovered the gray-shanked douc (Pygathrix cinerea) in 1997. Native to Vietnam, fewer than a thousand of the primates are believed to exist.

Two years ago an IUCN survey estimated that 65 percent of Vietnam's primate species were considered "endangered" or "critically endangered."

In August 2008 the conservation organization released a new report that estimates 70 percent of Asian primate species are considered "threatened," "endangered," or "critically endangered." The gray-shanked douc is among the primates that are now listed as critically endangered.
