 There are thousands upon thousands of species on planet Earth. Some creatures, the last of their kind. One out of five left in the world. I'm National Geographic photographer Joel Sartori, and I'm on a mission. Traveling the globe, doing whatever it takes... Not a bashful murder. He's got teeth. ...to capture them all, one portrait at a time. Wow, she's big. Rare. Creatures of the photo-art.
