自然生态 Some people say dolphins (海豚) are smart like humans. They can think, understand and learn things quickly. Scientists say dolphins are like humans in some ways. How?
Like humans, every dolphin has its own “name”. The name is a special sound. Each dolphin chooses a special sound for itself at birth (出生时). Dolphins are like people in other ways too. They “talk” to each other about a lot of things—such as their ages and finding food. They also use sounds and body language to talk. Knowing dolphin words is not easy for humans. No one speaks dolphin words, but some scientists are trying to learn.
Dolphins are also social animals. They live in groups, and often join others from different groups to play games and have fun—just like humans. Scientists believe playing together is something that only smart animals do.
Both humans and dolphins make plans for getting things they want. For example, when there are fish near a boat, dolphins jump high to ask the fishermen to put their nets, and then the fishermen can catch a lot of fish. Why do dolphins help the fishermen? Because they can get some fish that run away from the nets.
