What do wild animals do when we're not around? Find out with National Geographic's Crittercam. Safely worn by wildlife, Crittercams capture video, sound, and other information, giving students rare views of the private lives of animals. Crittercams help to solve scientific mysteries by providing an animal's eye view. And what scientists learn from Crittercams helps them protect the very animals that wear them. In this episode, scientists deploy Crittercam to study the hunting tactics, social behavior and vocalizations of humpback whales in Southeast Alaska.
