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.
