List of marine mammal species

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] This list follows the Society's taxonomy regarding and subspecies.
