Dolphin Altruism
"Several years ago, in the Gulf of Akaba, a British tourist was rescued by three dolphins from sharks. Near the Sinai Peninsula, a ship captain had stopped his boat so several passengers could watch dolphins playing. Three of the passengers decided to swim with them, and one stayed a little longer than the others. To his horror, he was bitten by a shark – and more were coming. Suddenly, three dolphins placed themselves between the tourist and the sharks, smacking the water with tails and flippers, and drove the sharks off so the man could be rescued.In 2004, a group of swimmers were confronted by a ten-foot great white shark off the northern coast of new Zealand. A pod of dolphins “herded” them together, circling them until the great white fled. There are several other examples from the area of Australia of similar incidences.
In another case in the Red Sea, twelve divers who were lost for thirteen and a half hours were surrounded by dolphins for the entire time, repelling the many sharks that live in the area. When a rescue boat showed up, it appeared that the dolphin pod were showing them where the divers were; they leaped up in the air in front of the rescuers, jumping toward the lost people as if to lead the boat onward – as, according to old stories, they often did with endangered ships in treacherous water.
Because we can’t talk to dolphins, we can’t really fathom what their motives are in these situations. It is, however, very possible that they are indeed trying to help and protect fellow mammals in the ocean to safety. If this is true, it means that they are the only animals, besides humans, which show true altruism."
