There are two orders that make up Marine Mammals:  the Cetacea (se-TA-she-ah) and the Sirenia (si-RE-ne-ah.) The cetaceans are the whales (the largest animals in the world) and porpoises, and the sirenians are the manatees and dudongs.  They're pretty big too!  Come join us and find out more about these wonderful sea mammals.
