Meet the
proboscis monkey (
Nasalis larvatus), a monkey only found in Borneo Island, Asia.
The proboscis monkey is one of the largest monkeys native to Asia. It's very easily identified (for obvious reasons).
The species has very pronounced sexual dimorphism, with the male being much larger than the female. Males also have much larger noses (the individual pictured is a male), but the noses of females are still very pronounced. The bigger the nose a male proboscis monkey has, the bulkier he will be — increasing his chances of attracting a large harem. Both sexes have bulging stomachs that give them the impression of having a pot belly.
The proboscis monkey is assessed as Endangered in the IUCN Red List of Threatened Species and listed in Appendix I of CITES. Its total population has decreased by more than 50% in the 36–40 years to 2008 due to ongoing habitat loss and hunting in some areas.
