Miller's Grizzled Langur, photo: Alexandr PospěchMiller's Grizzled Langur, photo: Alexandr Pospěch Presbytis hosei canicrus – let’s call him Miller's Grizzled Langur, is one of the rarest primates in the world, with hardly any pictures in existence and very few people having ever seen one. In fact it was believed that the long-tailed monkey was extinct, until scientists observing two natural springs in the Kutai National Park in Borneo came across one grizzled patron after another. Alexandr Pospěch is a photographer working with the team and he told me more about the long-lost langur, beginning with what it looks like.
