A dolphin’s forelimbs which are known as ‘pectoral flippers’. The forelimbs or ‘arms’ of a dolphin are the same anatomically as a terrestrial mammals legs. But the bones which make up the forelimbs in dolphins have been shortened and made more rigid by supporting connective tissue. These pectoral flippers allow the dolphins regulate their speed and turn.
Not all dolphin species possess a dorsal fin. The dorsal fin of a dolphin, which is located on the back, acts like a keel when the animal swims. This gives the dolphin directional control and stability within the water column. Northern rightwhale dolphins and the southern rightwhale dolphins however lack dorsal fins.
