Whale tales a thirty-year perspective on humpback whales in Alaska waters

Open All Close All

  • "Humpback whales are well-adapted to move through the ocean. Their bodies are streamlined with only a few bristles for hair on top of the head and no external ear flaps. Each whale has a nasal opening on the top of its head that allows it to exhale efficiently and inhale without lifting its head out of the water. Their powerful flukes, a modified 15-foot wide tail, propel them through the water. Humpbacks have the longest flippers (pectoral fins) of any whale, and the leading edge of the fin has ridges that increase their hydrodynamic efficiency. In this lecture, Professor Jan Straley will discuss her thirty years of research to understand the complexities of the lives of humpback whales. She will present the latest findings from a study spanning across the North Pacific, discuss her Alaska-based research and provide insight why some whales linger in colder waters during the fall and winter, when most whales, and sensible Alaskans, are migrating to the warmer climates of Mexico and Hawaii."
