Humpback whales (Megaptera novaengliae) can be found in Antarctic waters during the spring and summer in the Southern hemisphere, where they gorge on their main food source: tiny krill. How do they locate the small prey and maneuver their large bodies to eat? Scientists are looking at those questions and using different types of tags to learn more.
