British long-distance swimmer Adam Walker was making a 16-mile swim in New Zealand’s Cook Strait on April 22 when he noticed a great white shark swimming in the waters below him. He wasn’t the only one who spotted the predator. A pod of dolphins surrounded him and stayed with him for more than an hour until the shark swam away, according to various news reports and the incredible video above, shot from the chase boat accompanying Walker.
The video has notched more than 1.3 million views since it was posted the day after his swim. In the tweet below, Walker also posted several photos of himself and the dolphins, writing "I'd like to think they were protecting me and guiding me home!!!" The dolphins sometimes got close enough for Walker to touch them.
According to the Huffington Post
, “Walker, who was swimming to raise proceeds for the nonprofit Whale and Dolphin Conservation, embarked on the Cook Strait swim as part of the Ocean's Seven, a global challenge to complete seven long-distance swims. He crossed the Cook Strait in eight hours and 36 minutes.
“Walker is already most of the way through the Ocean's Seven challenge, having previously completed swims across the English Channel, Strait of Gibraltar, Molokai Channel, Catalina Channel and Tsugaru Channel,” reports the Huffington Post. “His final swim will be in August, when he will attempt to swim the North Channel, which separates Northern Ireland from Scotland.”
