come in many different shapes and sizes. They can be as small as four feet (1 1/4 meters) long weighing just 100 pounds (45 kilograms), or as large as 30 feet (nine meters) long weighing up to 11,000 pounds (950 kilograms). All dolphins, including even the largest, can move quickly through the water, using paddle-shaped forelimbs called flippers to steer, dorsal fins on their backs to stay balanced, and powerful tail fins called flukes to move forward. Their torpedo-shaped bodies flow smoothly in the water, so they don't make many waves. They use their flippers to make sharp turns and sudden stops. All dolphins have blowholes on the tops of their heads. These mammals breathe through their blowholes. They have to go to the surface of the water to breathe. Each dolphin has just one blowhole.
