Can dolphins talk? Maybe they can't talk with words, but they talk with sounds.

Dolphins travel in a group. We call a group of fish a "school". They don’t study but they travel together.

Dolphins talk to other dolphins in the school. They give information. 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 water. People can't hear these sounds because they are very very high. Scientists make tapes of the sounds and study them.

Sometimes people catch a dolphin for a large aquarium(水族馆). People watch the dolphins in a show. Dolphins don’t like to be away from their school. In the aquarium they are sad and lonely. Dolphin meat is good but people don't like to kill them. They say that dolphins bring good luck. Many people believe this.
