Can dolphins talk? maybe they can’t talk with words, but they talk with sounds. They show their feeling with sounds. They travel in a group. We call a group of fish a ‘school’. They don’t study, but they travel together. Dolphins are mammals, not fish, but they swim together in a school. Dolphins talk to the other dolphins in the school.

They tell when they are happy or sad or afraid. They say ‘welcome’ when a dolphin comes back to the school. They talk when they play. They make a few sounds above water. They make many more sounds under the water. People cannot hear these sounds because they are very, very high. Scientist make tapes of the sounds and study them.
