Photographer Captures Hilarious Close Up Portraits of Some of the World's Most Unusual Primates

For over two decades, photographer Mogens Trolle has captured stunning wildlife photos on all seven continents. Trained as a zoologist and wildlife biologist, he specializes in mammals and uses his knowledge of them—as well his keen eye—to capture each creature’s unique personality.

His photographs, especially those of monkeys, showcase micro-expressions that look like the kind we're used to seeing on other humans. Hilarious close-up portraits of some of the world's most unusual primates show their uncanny resemblance to humans.
