their own language. But they are quite different from almost all land animals. Their brain(大脑)is as big
as men"s and they live a long life at least 20 or 30 years.
Like some animals, dolphins use sounds to help them find their way around. They also use these
sounds to talk to each other and to help them find food. They do not use their ears to receive sounds,
but use the jaw--the lower part of the mouth.
It is strange that dolphins are friendly to men, and for thousands of years, there are many stories
about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand,there
was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to
1903 ,Jack met every boat in the area and showed it the way. In 1903 a passenger on a boat with the
name of The Penguin shot and hurt Jack. Luckily the dolphin didn"t die, and after a long time he was
well again. He guided the ships through the area for nine more years, but he refused to help the boat
of the Penguin.
Today, some people still kill dolphins, but many countries in the world now protect them. In these
places, people are not allowed to kill them.
