It's known as the monkey that sneezes in the rain.

According to locals, these monkeys are easy to find when it rains. Their upturned noses catch water, which reportedly makes them sneeze. We don't know this for sure as its not yet been tested.

The Burmese snub-nosed monkey (Rhinopithecus strykeri) was only discovered in 2010 and brings the number of snub-nosed monkey species to five.

They only live in China and Myanmar but are already listed as critically endangered by the International Union for Conservation of Nature.

They are extremely hard to observe in their natural habitat. A team says, in the International Journal of Primatology, that unmanned camera traps offer unprecedented access into their lives, without the need to disturb them.

Photos like this can give us new insights into these rarely observed oddball monkeys.

The team discovered that they are most similar to their cousins, the black and white snub-nosed monkeys.

They also live in large societies with clusters of groups consisting of one male and his harem of females. There are also one or more all male fringe groups.

This type of "multilevel social organization is relatively rare across nonhuman primates," the team report.

Researchers hope that new insights into their habitat and social lives will help with their conservation.
