Martin Richardson was swimming in the Red Sea in Egypt when he was attacked by a mako shark (Isurus oxyrinchus). He was bitten approximately five times and was waiting to die when something unusual happened.
"There was no reason for the shark to stop," he said in "Saved from a Shark," a new show from National Geographic. "I had lost approximately 5 pints [2.8 liters] of blood. You only have 8 to 9 [pints, or 4.5 to 5 L] in your body. I was waiting for a feeding frenzy… I knew it was circling me… I turned away and looked at the mountains. I gave up."
