It's good to have friends. Especially when you're surrounded by sharks.

Check out this video of swimmer Adam Walker as he attempts to be only one of just four people in the world to swim the hardest seven oceans. Walker is on a quest to aid the Whale and Dolphin Conservation charity Just 4 Whales.

Walker spotted a six-foot shark beneath him which was followed shortly by a group of 10 dolphins coming to the rescue. The full story can be read here and the video can be seen below.
