The awe-inspiring moment a whale shark rose from the deep and swam alongside humans has been captured in stunning aerial footage.
The gentle giant - the largest fish in the world - dwarfs the tiny figures in the amazing rare video.
It was filmed off the coast of Baja California Sur, Mexico, which from early winter to late spring is a haven for the beautiful beasts.
They return every season to the bay waters close to the city of La Paz.
Aerial cinematographer Tarsicio Sañudo Suarez, 36, said it was a "special" moment when he realised what was happening.
“At that moment I was in a boat with the people of the Whale Museum of La Paz," he explained.
