Additional information
The blue whale can be confused with the fin whale Balaenoptera physalus but is recognised by its broad and U-shaped head, a very small dorsal fin that is set far back on the body, and symmetrical head colouration. Blue whales are usually found alone or in pairs, although in feeding areas up to a dozen have been seen together. It rarely breeches, and when diving, it will often show the tail flukes. Dives may last up to 30 minutes long (Kinze, 2002).Listed by
