This is an interesting video, locals would describe seeing this monkey and people would brush it off as folklore.
Fauna and Flora International has captured the world’s first video footage of Myanmar Snub-Nosed Monkey. This new species (Rhinopithecus strykeri) was discovered in 2010 and has remained hidden from video cameras up until now. This is the first species of snub-nosed monkey to be discovered outside.
