For many years, many people believed that the cleverest animals after man were the
chimpanzees. Now, however, there is proof that dolphins may be even cleverer than
these big apes.Although a dolphin lives in the sea it is not a fish. It is a mammal.
It is in many ways, therefore, like a human being.
Dolphins have a simple language. They are able to talk to one another.
It may be possible for man to learn how to talk to dolphins. But this will not
be easy because dolphins cannot hear the kind of sounds man can make. If man
wants to talk to dolphins, therefore, he will have to make a third language which
both he and the dolphins can understand.
Dolphins are also very friendly toward man. They often follow ships. There
are many stories about dolphins guiding ships through difficult and dangerous water.
