"Humpback Whale," Wikipedia, the free encyclopedia. The varying patterns on the tail flukes are sufficient to identify individual humpback whales. A photographic catalogue of all known North Atlantic whales was developed and is currently maintained by College of the Atlantic. Similar photographic identification projects have begun in the North Pacific by Structure of Populations, Levels of Abundance and Status of Humpbacks, and around the world. Special thanks to Laura Howes, Director of Marine Education & Conservation, Boston Harbor Cruises, with assistance in identifying the whale.
