Self Portrait - Crested Macaque (Macaca Nigra)
Photographer David Slater was taking pictures in a national park on the island of Sulawesi in Indonesia, when this fella managed to take a self portrait.
"They were quite mischievous, jumping all over my equipment, "Slater said. "One hit the button. The sound got his attention and he kept pressing it. At first it scared the rest of them away but they soon came back - it was amazing to watch."
