This is the heartwarming moment a giant, 50,000-pound humpback whale protects a marine biologist from a nearby shark by shielding her and pushing her out of harm’s way. The hypnotising footage was filmed in the waters off Muri Beach, Rarotonga, of the Cook Islands in the South Pacific. Whale biologist Nan Hauser says the humpback protected her and her team from a circling tiger shark by putting her under its fin and using his head and mouth to push her away. he 50,000lb mammal can also be seen tucking the 63-year-old under its pectoral fin and it even lifts the biologist out of the water at one point. Nan said the incident, which occured in October, is proof of the whale’s intuitive nature to protect other species of animal – including humans – something she believes has never been captured on film. The biologist compared this to firemen being willing to rush into a burning home to help save the lives of strangers. Surrounding the unsuspecting snorkeler and the roughly 14-metres-long mammal was a 15-foot tiger shark.
