Now this is a fierce shoot!

The Daily Mail posted an article of fashion models who took fashion underwater, striking a pose alongside 30-foot-long whale sharks.

Holding their breaths, the models posed for breathtaking photos 25-feet into the ocean.

Dressed in designer attire, with some models topless or all together naked, international fashion models, Hannah Fraser, 36, and Roberta Mancino, 32, shared the frame with the 18-tonne world’s largest fish.

US photographers Shawn Heinrichs, 41, and Kristian Schmidt, 35, spent four months planning the five day photoshoot, according to the Daily Mail.

Heinrichs said the models were “incredibly eager” to be part of the shoot.

“As well as being conventional models in the fashion industry, Hanna is a professional underwater model and Roberta a world-class base jumper,” Heinrichs said.

It was all the background both models needed to make the photo shoot a success.

The photos were taken in the Philippine village of Oslob where fishermen in the area have developed a special bond with the whale sharks by feeding them small handfuls of tiny shrimp.

The photographer explained that for “a few hours a day, the whale sharks sit peacefully beneath the canoes waiting for a tasty treat.”

“I had a real sense of how to work with human subjects and these magnificent animals,” he said, adding that his partner Kristian is skilled at “working with fashion models”.

Heinrichs credited the success of the shoot to the combined expertise of the photographers and the “experience, confidence and natural beauty” of the models.

The resulting images have “blown away” many, he said.

“Most find it hard to believe they are actually real – many people assume the models are photo-shopped into the picture.”

Heinrichs explains only the colour and lighting has been enhanced, but the models and shark underwater are very real.

It is the juxtaposition between the beautiful and vulnerable women and far larger and more powerful sea creatures that has captivated many.
