Dolphins are very clever animals. They are usually not more than 3.3 meters long. They are found in many parts of the world. Dolphins like living together. Sometimes people can see groups of them swimming and playing in the water. It is impossible to tell how many there are around one ship, but there may be thousand . Dolphins live on fish but they do not spend all their time looking for them. They can spend more than six minutes below the surface of the water without coming up for the air. Scientists say that dolphins are very much like human. So it might be possible to teach them to talk. But not all the habits of the dolphins are the same as those of men, though it is certain enjoy being with humans. Perhaps that is why they often go around after ships.
