These pink-bottomed, punk-haired monkeys are the most endangered of the seven macaque species that live on the island of Sulawesi (formerly Celebes) in Indonesia. The main threat to their survival is over-hunting for food – they are served up as a delicacy on special occasions such as weddings. The all too common problem of habitat loss to humans for farming and housing puts additional pressure on the macaque population. www.emanueledelbufalo.com
