Extreme swimmer Adam Walker from Nottinghamshire has been protected from a shark by a pod of dolphins.
The shark was lurking underneath him in the Cook Strait in New Zealand when the dolphins formed a protective ring around him, even after it had gone they stayed with him for another hour.
Adam from Kelham has become the only Briton ever to successfully complete the world's toughest open water challenge, Oceans Seven.
Only 4 people in the world have ever achieved this.
Adam's impressive list of watery conquests:
