Dolphins are intelligent aquatic mammals of different sizes and colours. Even though dolphins move around by swimming, they also often jump out of the water for various reasons.
1. One of the most commonly mentioned reasons is that dolphins leap out of the water to conserve energy while travelling, as moving through air uses much less energy than through water. Jumping into the air while swimming also allows the dolphin to breathe without losing stride.
2. Dolphins also jump in an attempt to find food, similar to the way birds scan for fish from above the water. They jump to locate food or food related activity like seagulls eating or pelicans hunting.
3. Dolphins also use jumping as a form of communication with other dolphins. They also communicate through various vocal sounds such as whistling and clicking. They splash as a warning of danger.
4. Dolphins might jump to shake off parasites such as barnacles or sucker fish. In addition, they also may jump to escape small attacking sharks.
5. Dolphins are extremely playful creatures and they show their playfulness by jumping out of the water. Spinner dolphins, for instance, leap from the water and do several corkscrew spins before hitting the water again.
