Yet it is not only domesticated animals who have acted heroically. There are also stories of wild animals coming to the rescue of humans. One animal known to be a friend and protector of humans is the dolphin. Dolphins are considered to be among the most intelligent of animals. On dozens of occasions, they have use this intelligence to come to the aid of humans in dangerous situations. One such story involves a surfer named Todd Endris. Todd was surfing with his friend when he was attacked by a 13-foot (4-meter) shark. In the middle of attack, a group of dolphins came to his rescue by forming a protective ring around Endris until he could get safely to shore. Without the help of the dolphins, there is little chance that Todd would have survived.
