Dolphins have very good eyesight, although they also use their hearing to navigate their way around the ocean water. Dolphins, like other toothed whales, use echolocation to find food. They will make short clicks and listen for the echoes, which reveals the location of the fish. Dolphin pods will chase fish, sometimes swimming nearly 25 miles per hour, before encircling a school of fish. As the pod keeps tight control of the fish, individual dolphins will swim into the school and take turns eating. Dolphins will also chase fish into shallow water. This is called corraling, and it helps the dolphins to capture the fish easier. Bottlenose dolphins will sometimes drive fish onto muddy banks for capture. Some dolphins will use their flukes to stun their prey, sometimes flipping them out of the water.
