Taxonomy

Whales, dolphins and porpoises belong to the Order Cetacea. The following taxonomy provides the most complete and up-to-date* reference in terms of current research in the field of cetacean classification. The list provides common (vernacular) names, scientific names and the names of subspecies where these have been described. A number of the subspecies below have not yet been named, and in such cases these are simply referred to as subsp. in the list. The common names assigned for these animals are typically based upon their distribution.

The links below are directed to a detailed fact sheet for those cetacean species most commonly found in the Moray Firth study area.

Order CETACEA (87 species)

Suborder MYSTICETI: The Baleen (Moustached) Whales (14 species)

Baleen whales are filter feeders which sieve food from the seawater with baleen – hair-fringed plates made from keratin (the same material as our fingernails). The minke whale is the most common of the baleen whales in the Moray Firth, although other mysticete species recorded in these waters include the fin whale, sei whale and the humpback whale.

Suborder ODONTOCETI: The Toothed Whales (73 species)

This group contains the beaked whales (Ziphiidae), the freshwater river dolphins, the beluga and narwhal (Monodontidae), the dolphin species (Delphinidae), the porpoises (Phocoenidae) and the sperm and pygmy sperm whales (Physeteridae and Kogiidae). Of the beaked whales, only the Northern bottlenose, Sowerby's beaked whale and the Cuvier's beaked whale have been recorded in the Moray Firth. Sperm whales sporadically occur in this area of the North Sea, but the individuals entering this shallow Scottish firth usually become stranded on the beaches.
