How many Cetacean species are there?
Not too many people know that there are about 86 species of whales, dolphins and porpoises in the Order Cetacea. Not too many people know that this word comes from the Latin cetus meaning “a large sea animal,” and the Greek word ketos, meaning “sea monster.” Anyway, it is interesting to know that these populations are very often re-classified. Needless to say, the order Cetacea is divided into two sub-orders, the Mysticetes (baleen whales) and the Odontocetes (toothed whales). Keep in mind that the Odontocetes are more numerous.
