Even if you have traveled to every piece of land on the planet, in reality, you’ve only seen 30 percent of the Earth’s surface. That’s because the remaining 70 percent is covered by the ocean—much of which has yet to be explored. Massive, majestic, and mysterious, seeing imagery of life in the ocean is always something that fills you up with wonder. And unlike taking photos on land, the art of capturing the underwater world is a much more challenging endeavor. With all of that in mind, have a look at the winners of the 2019 Underwater Photographer of the Year Contest. The stunning photos will remind you how everything is different below the shade of the waves.
