Marine mammalogy is the study of whales, dolphins, porpoises, seals, sea lions and other marine mammals.
Several organizations are dedicated to the study and protection of marine mammals.
Along the west coast of North America, you can watch the Gray Whale make its annual migration from its feeding grounds in Alaska to its birthing lagoons in Mexico, either from shore, in some places, or aboard a whale watching vessel. The best type of boat to go whale watching on is a sailboat, because it is often quieter and many times offers a better view of the whales.
