This monkey's nose is so upturned that rain reportedly makes it sneeze

Described as a new species in 2010 from a carcass and skulls found in northern Myanmar, Rhinopithecus strykeri has nostrils so upturned that local hunters say they can track it in the rain by listening for its sneezes. The species is so rare and remote that scientists named it before anyone got a usable photo of a live one.
