Dolphins , like whales , must surface to breath air through a blowhole on top of their heads. Dolphins are social animals and love company. Many of them , in fact , even enjoy being around humans . It is not uncommon to hear of dolphins giving rides through the water to humans. In additions to being playful, dolphins are helpful to men . For example, as early as 400 B. C . the Greek poet Arion was saved from drowning by a dolphin . From then until now , dolphins have been helping swimmers who are in trouble. Swimmers, however are not the only humans they help. In some parts of the world , they can be counted on to help men catch fish. Moreover , dolphins are very intelligent. A dolphin's brain resembles a human brain , but it is large. Consequently, some people claim that dolphins are really smarter than men . Of course, there is no way of proving this point. Brain size is not an absolute measure of intelligent. Furthermore measuring dolphins' intelligence on other ways is not possible since men cannot fully communicate with them . Apparently, however, dolphins communicate with e
ach other . At any rate , they make whistling, clicking and buzzing sounds which seem to be at least a form of language . So far , however , men have not been able to figure out the communication code the dolphin use.
