Swimming together, they create waves so powerful and accurate, they can wash a seal right off a piece of floating ice—some of the most sophisticated behavior in the animal kingdom. The hunting technique of pack-ice killer whales has intrigued scientists for decades, and there is still so much unknown about the species. Each scientist on the expedition hopes to discover new truths about these whales.
