Creature Clip: Dung Beetles

Every creature, no matter how big or small, stinky or clean (and these dung beetles sure are stinky!), deserves a place in the Photo Ark, Joel Sartore's lifelong project to capture the world's biodiversity in photography. Watch episode 2 of RARE: Creatures of the Photo Ark Tuesday, July 25 at 9/8C on PBS (check local listings).
