Cetacean Species and Taxonomy

The number of recognized cetacean species and subspecies is being continually revised and re-examined on the basis of new scientific data.


The Society for Marine Mammalogy’s ad hoc Committee on Taxonomy, chaired by Patty Rosel, has produced the official SMM list of marine mammal species and subspecies. This list is revisited every few months and, when necessary, is revised to reflect the continuing flux in marine mammal taxonomy.
