Dolphins (海豚) are very clever animals. They are usually not more than 3.3 metres 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 thousands. 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 (表面) of the water without coming up for air. Scientists say that dolphins are very much like humans. So it might be possible to teach them to talk. Some of the habits of dolphins are not the same as those of men, though it is certain that dolphins enjoy being with humans. Perhaps that is why they often go round after ships.
