Taxonomy of Whales
Classification of the order of Cetacea (whales, dolphins and porpoises)
On this page
TAXONOMY
Taxonomy represents our attempts to classify nature. The methods used to designate species and subspecies are varied and not always precise. In recent years, genetic information has been used to reclassify certain previously accepted designations of species and subspecies. Such work continues. In fact, from a management perspective, information at a smaller level than species (i.e. populations) is required. The tables below represent the list of scientific and common names accepted by the IWC Scientific Committee at the time of writing. Note that the common name ‘whale’, is often associated with species other than the ‘great whales’ (the baleen whales plus the sperm whale).
The 1946 Convention does not define a ‘whale’, although a list of names in a number of languages was annexed to the Final Act of the Convention. Some Governments take the view that the IWC has the legal competence to regulate catches of only these named great whales (the baleen whales and the sperm whale). Others believe that all cetaceans, including the smaller dolphins and porpoises, also fall within IWC jurisdiction.
The following tables are split into baleen and toothed cetaceans and include all species currently recognised by the Scientific Committee.
