Join National Geographic on a journey to the Arctic where wildlife filmmaker meets bowhead whale — one of nature's most long-lived mammals. Not much is known about this mysterious giant, but with a little help from National Geographic's Crittercam® the filmmaker gets a breathtaking glimpse into the whale's secret world. The revealing footage has helped researchers discover how these whales can survive centuries in their freezing habitat. National Geographic also heads to Japan where a brave researcher faces a powerful but tiny predator. He's a hornet hunter and has experienced first-hand the insect's potent venom. Now he's on a mission to find the key to diffusing the hornet's painful sting.
