How many Cetaceans are there?

Not known

The exact number of Cetaceans is not known.  It is important to understand that the Cetaceans are formed of whales, dolphins and porpoises.  They currently include 89 species that inhabit the world’s oceans, lakes and rivers.  Not too many people know that some Cetaceans are exclusively marine, others are freshwater, and some are both.  Keep in mind that Cetaceans are relatively large, generally characterized by streamlined bodies that glide easily through the marine environment.  Needless to say, Cetaceans are broken into two Suborders, or main groups: Mysticeti and Odontoceti.
