Marine mammals are classified into four different taxonomic groups: cetaceans (whales, dolphins, and porpoises), pinnipeds (seals, sea lions , and walruses), sirenians (manatees and dugongs), and marine fissipeds (polar bears and sea otters ).
Seals and sea lions are semiaquatic mammals that are in a group called pinnipeds, meaning “fin-footed.” Walruses are also members of this group.
