Some dolphins can jump as high as 25 feet above the water's surface. Juvenile spotted dolphins have been observed jumping 15 feet. Spinner dolphins get their name from the fact that they spin while jumping. Spinner dolphins can complete seven revolutions in the air before hitting the water.
Wild dolphins use jumping and spinning to communicate with each other. They also jump as a form of play and to show off to each other. Some researchers speculate that dolphins sometimes jump in order to get a better view of the area. Predators and schools of fish may be easier to spot from above.
