F. WAITING FOR THE DOLPHINS TO COME

PEOPLE AND DOLPHINS WORKING TOGETHER

4.1.

When the scientist Paulo Lopez arrived in the Brazilian town of Laguna twenty years ago, he was surprised by a strange sight. He saw dolphins help the local fishermen catch fish! Lopez, who studies dolphins professionally, was so amazed that he decided to find out why they do it.

4.2.

These dolphins swim slowly to push mullets, a kind of small silver fish, towards the fishermen. Then, they splash water with their heads or fins to show the fishermen where to throw their nets. The fishermen catch some fish, and most of the fish that manage to escape the nets swim right into the dolphins' mouths.

4.3.

Many fishermen in other places see dolphins as competitors, but not in Laguna. On days when the dolphins don't appear, the fishermen know it's not worth fishing. They have nothing to do. They just sit on the beach, look at the rough sea and hope their animal friends will soon turn up.

4.4.

Nobody really knows how this cooperation began, but local fishermen say that it's been going on for over 100 years. People don't teach young dolphins any tricks, though. Mother dolphins show their babies how to work with humans, and fishermen teach their children how to cooperate with the dolphins. In this way, the tradition continues.
