The whales are the largest animal to ever inhabit the earth, and outsize even the biggest dinosaurs.

Patrick swam with the animals in the Indian Ocean off the coast of Sri Lanka, on various trips between 2009 and 2015.

The 35-year-old said: "It was a dream of mine to encounter a blue whale underwater from the time I was 16 and I saw a life sized replica of a blue whale in the Smithsonian Museum.

"I spent over a decade travelling the world in search of blue whales in clear water, from Antarctica to the Azores, and came to Sri Lanka in 2009 and found the clearest water and a large whale population.

"Nothing on earth compares to the experience of being side by side with the largest animal to ever inhabit the planet and to dive into it’s environment.

"I use my photography and videography to help study these animals in the hopes of understanding and protecting them."
