Dolphins are considered one of the most intelligent creatures in the animal world. In fact, some dolphins in Brazilian town of Laguna have created a rare relationship with humans to catch fish. To keep the party equal, the sea animals and the fisherman teamed up to bring their food on the table.

About 20 dolphins are working with people in Laguna to catch fish, and residents recognize each one of them because of their markings. The bottlenose dolphins send signals to fishermen to let them know where to put their fishing nets. In this way, it would be easier to the people and dolphins to get their food.

The dolphins were not trained to do this task. According to scientists, this behavior was passed down from one generation to the next.
