(WREG-TV) While swimming New Zealand’s Cook Strait, Adam Walker looked down to see a great white shark.
A pod of about ten dolphins then appeared, staying with him until the shark left more than an hour later.
Walker’s 16-mile swim was part of the Oceans Seven mission. The challenge consists of seven long-distance open-water swims.
He’s also raising money for the nonprofit Stop Whaling, which supports whale and dolphin conservation.
“I’d like to think they were protecting me and guiding me home!” Walker wrote on Facebook. “This swim will stay with me forever.”
With the English Channel, Gibraltar Straits, Catalina Channel, Molokai Strait, Tsugaru Strait and now the Cook Strait under his belt, Walker’s final swim of the seven takes place this August in the Irish Sea.
