Interesting as dolphins (海豚) are to scientists, it is their intelce and sociability that have caught the popular imagination. Like whales, dolphins have a strong sense of family. A dolphin family is like a human family, but much larger. Dolphins seem to be among the most sociable of all living creatures. They enjoy playing with each other and also with the humans, with whom they come in touch. It is this characteristic that makes them so easy to train as star performers. Besides, they seem able to remember humans that they have met even when there is a long period of time between meeting. A sense of family and a spirit of cooperation appear to be very strong among all these marine animals. There are many recorded cases of dolphins supporting a sick animal on the suce of the water so that it will be able to breathe. Language has always been considered unique to human beings. It now seems that the cetaceans (鲸目动物) may be able to communicate with each other through sounds similar to a real language. Scientists are studying the behavior of the cetaceans, the sounds they send out and the physical characteristics of their brains in an effort to determine whether they really have the ability to communicate through language. It may prove that we’ll be able to establish real communication with another species for the first time.
