Watch A Free-Diver Rescue This Entangled Whale Shark | National Geographic
20 August 2018
A Hawaiian family spotted this whale shark while free-diving off the coast of Lanai. First, they were excited about the rare sighting of the 20-foot-long endangered shark. But then, they noticed a heavy rope tightly wrapped around its neck. Biologists Kapua Kawelo and Joby Rohrer decided to help the animal, while their son, 17-year-old Kanehoalani, filmed the rescue.
