The National Marine Mammal Laboratory's Education Website, which targets K-12 learners, provides basic information on marine mammals, including whales (baleen and toothed, dolphins, and porpoises). Still under construction, the site will eventually provide pages on seals, sea lions, walruses, manatees, and dugongs. Educational tools currently include a Marine Mammal Quiz and a List of Endangered Marine Mammals. Additional information covers careers in marine mammal science. For more advanced information on marine mammal research, see the National Marine Mammal Laboratory homepage.
