Question

    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 are mammals, not fish, but they swim together in a school. 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.
