Photographers capture underwater life in amazing detail for competition
Catalin Craciun/UPY 2017
"The idea for this photo came from the need to show people that freediving is not only about going down and up on a line but rather exploring, dreaming and applying it for having fun and to explore."
Beneath the surface of the sea, lakes, rivers and even swimming pools lies spectacular photo opportunities.
That's what photographers from 67 countries found when they entered the annual Underwater Photographer of the Year awards.
But among the amazing shipwrecks, a stunning photograph of a hunting octopus took out the top prize.

Francis Pérez/UPY 2017
Francis Pérez spent four hours getting close to sea lions in Mexico to capture this incredible image.
"I had to wait for a low spring tide when the water was just 30cm deep so that the octopus would fill the water column. I got as close as possible with a wide angle lens to create this image, which makes the octopus look huge."
