Intelligent Animals For many years scientists believed that the chimpanzee was the most intelligent animal in the world---not including human beings. But now they are not so sure. Recently they have learned that dolphins are very intelligent too --- perhaps more intelligent than chimpanzees. Many people think that dolphins are fish, but this is not true. Dolphins are different from fish in many important ways. They are mammals. They are warm-blooded, and they cannot stay underwater all the time like fish. They breathe air. They have to come to the surface of the water and take in air every few minutes. Dolphins live in groups, or schools. Schools of dolphins travel and catch fish together. They use a kind of language to communicate within the group. Scientists to not understand the language, but they know that dolphins can talk to each other and send messages underwater. Dolphins are very friendly to people, and they are helpful too. A few dolphins have already been trained to do useful things. They carry messages quickly between ships, they find lost objects in the ocean, and they carry equipment underwater to collect information for scientists. In the ocean, and they carry equipment underwater to collect information for scientists. In the future, dolphins could become the most useful animals in the world. intelligent [in'telidʒent] adj. 智能的；聪明的；理解力强的 chimpanzee [,tʃimpən'zi:] n.
