            1. Communicate with clicks and whistles

              Annotations:

              • Videos of dolphins communicating both in captivity and the wild: https://www.youtube.com/watch?v=YSjqEopnC9w https://www.youtube.com/watch?v=4Un61qv_QIc

                  1. Amazon River Dolphin
                    1. Orcas

                      Annotations:

                      • Though commonly referred to as "Killer Whales", Orcas are actually part of the order Cetacea, which excludes whales and porpoises. http://animals.nationalgeographic.com/animals/mammals/killer-whale/ 
                  2. Whales
                    1. Behaviors
                      1. Feeding using "Bubble Net Fishing"

                        Annotations:

                        • Here is an amazing video displaying this hunting technique used by pods of whales: https://www.youtube.com/watch?v=z00G0RxeSP0
                        1. Live both in pods and solitary

                          Annotations:

                          • More so than dolphins, many whale species prefer traveling alone or with flexible and dynamic groups. The strongest bonds occur only between a mother and her calf. http://www.enchantedlearning.com/subjects/whales/glossary/Pod.shtml
                          1. Communicate with song-like noises
