Are dolphins the only creatures, aparm from man, able to talk toeach other? After all the dolphin is a mammal, has a largs brain,and has been observed to make various noises which might be part of a communication system. An American scientist recently tried to answer this guestion. He kept two dolphins, one male, one femle,in a large tank and trained them to work together. According to whether a steady or a flashing light came on they had to press one of two levers.When they pressed the correct one they were rewarded with fish.
They were later separated by a screen so that they could not see each other. Only the female dolphin could see the lights but both hed to press the same lever to get the fish. The female would have to tell the male which lever to press.
In the experiment the male succeeded in pressing the correct lever 90% of the time.
