National Geographic photographer Joel Sartore has spent the past ten years working on a massive project to document the world’s biodiversity, called the Photo Ark. The April issue of National Geographic magazine features Sartore’s portraits. Over the past decade, he has photographed more than 5,600 animals and says he won’t stop until he’s documented every one of the estimated 12,000 birds, fish, mammals, reptiles, amphibians, and invertebrates in captivity.
