Marine mammals comprise over 130 living and recently extinct species in three taxonomic orders.The Society for Marine Mammalogy, an international scientific society, maintains a list of valid species and subspecies, most recently updated in October 2015. [1]
Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), sea otters and polar bears. They are an informal group, unified only by their reliance on marine ...
The Low Country Marine Mammal Network has studied a behavior among resident dolphins known as “strand feeding” that seems to be unique to the Carolina and Georgia coasts. The animals work ...
The U.S. Navy Marine Mammal Program (NMMP) is a program administered by the U.S. Navy which studies the military use of marine mammals - principally bottlenose dolphins and California sea lions - and trains animals to perform tasks such as ship and harbor protection, mine detection and clearance, and equipment recovery.
Dolphins are mentioned far more often than whales. Aristotle discusses the sacred animals of the Greeks in his Historia Animalium. The Greeks admired the dolphin as a "king of the aquatic animals" and referred to them erroneously as fish. Dolphins appear in Greek mythology. Because of their intelligence, they rescued multiple people from drowning.

With their white or sometimes pale brown coloration, fishermen tend to call them "the white ghost", as they also tend to stray away from any human interaction.
