COMMUNICATION
Dolphins communicate by clicking ,creaks ,and whistles . Each click a person hears is made up of split second clicks. Dolphins click to communicate when there is food ,or if they need help or for other reasons. Dolphins are very intelligent creatures and have large brains. When a dolphin is excited or afraid , they make a high pitched squeal or whistle. The dolphins sound is made from a melon right below the blowhole. dolphins use these clicks as a kind of sonar. The echo bounces off schools of fish or other water like creature.
