"Dolphins Rescue Man from Shark Attack, Defying Death"

A man who was attacked by a shark while swimming in the Red Sea believes that a group of dolphins saved his life. Martin Richardson, who was bitten multiple times by a mako shark, was waiting to die when the dolphins appeared behind him, causing the shark to retreat. While experts suggest that dolphins may not intentionally save humans, there have been cases where they have protected people from sharks. The incident is explored in the National Geographic show "Saved from a Shark," which examines instances of animals seemingly protecting humans from predators in the water.
