Dolphins are believed to be very intelligent animals. They seem to be able to think, understand, and learn things quickly. Many scientists believe there is a special connect ion between dolphins and humans. There are lots of amazing stories about dolphins and humans. Here are two of our favourites.

Although dolphins use their brains differently from people, they are similar to humans in a way: both make plans to get something they want. In the seas of southern Brazil, for example, dolphins use an interesting strategy to get food. When fish are near a boat, dolphins show signs to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins in doing so? They get to eat some of the fish.

Another story is about dolphins as a lifeguard to help save humans in danger. In 2016, Ad-am Walker went to New Zealand to swim across the Cook Strait between the North and South Islands. He was swimming when he saw a large dark shape below him. He knew that it was a great white shark and his life was in danger. Adam knew he didn't have a lot of time. A few seconds later, a group of ten dolphins joined him and swam in a circle between him and the shark. The circle of dolphins kept Adam safe. After half an hour, the shark left, but the dolphins swam with him for another hour.
