In 2002 Grant Dickinson was working on a fishing boat off Queensland, Australia. During a storm, the boat sank. Grant cut himself and was left bleeding in the water while he waited to be rescued. But as he waited, he saw some sharks swimming around him. One shark came closer and closer. Grant was very afraid. He thought that the shark would soon attack and eat him. Suddenly, a group of dolphins appeared. They swam in a circle around him and chased the sharks away. The dolphins stayed with Grant until another boat came and rescued him a few hours later.
