Rare -- Creatures of the Photo Ark

National Geographic photographer Joel Sartore explores different countries and looks for rare and endangered animals, capturing their majesty through photographs. From mammals, fish and amphibians to birds, reptiles and insects, Sartore documents threatened species at zoos, in nature preserves and other locations around the world. Some segments include a search for key deer in Florida, looking for the Yangtze giant softshell turtle in China, and documenting bizarre, rare insects in Budapest and Prague.
