Dolphins are not fish. They are mammals(哺乳动物). They live in groups and speak to each other in their own language. But they are quite different from almost all land animals. Their brain 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 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 all the ships and boats in the area and showed them the way. In 1903 a passenger on a boat with the name of The Penguin shot(拍照) a long time in the area. Jack guided the boat The Penguin until the passenger finished.

Today, some people still kill dolphins, but many countries in the world now protect them. Dolphins are humans’ friends. Let’s all be nice to them.
