Celebes Black Macaque, IndonesiaThe Celebes black macaque (Macaca nigra), also known as the crested black macaque, is found only on the Indonesian island of Sulawesi and a few nearby islets. With jet-black fur, a mohawk-like crest, and intense amber eyes, Celebes black macaque’s are one of the most visually distinctive primates in the world. They’re known for their expressive faces, especially their smile, which is actually a sign of submission. Sadly, they are critically endangered due to habitat loss and hunting, making their conservation especially urgent. Nikon D700 with Nikkor 17-35mm lens (at 32mm) ISO 800, f/2.8 at 1/125th of a second.
