For the more aggressive people, the killer whale is suitable because of its fierce predatory nature. Some might choose to like the white-beaked dolphins because of their short, thick and creamy beaks and very falcate dorsal fin. The pink river dolphin is also a favorite among many because of its pink skin which is due to the fact that their capillaries are so close to their skin, filling with blood (oxygenated) giving the dolphin the look of pink.

Other contributing reasons set different dolphins to be as favorites. For instance the bottlenose dolphins are very much popular since they are very friendly and can be tamed easily. They are playful and fun to be with because of which they are also commonly found in zoos to attract human attention. Altogether, nearly all dolphins are beautiful and have their own abilities which distinguish them from each other and it is these qualities that make us choose our favorite species.
