Heads up, Ariel: There's something positively mind-blowing going on under the sea.
These absolutely gorgeous photographs just made a big splash in the international Underwater Photographer of the Year competition for 2018. The annual contest showcases more than 100 of the world's best photos captured in oceans, lakes, rivers, and even swimming pools. With winners in 11 categories, including portraits, wide-angle, and wrecks, the competition brings out seasoned professionals and rising stars in this beautiful — albeit somewhat soggy — hobby.
Underwater photography greats Peter Rowlands, Martin Edge, and Alex Mustard judged more than 5,000 entries to crown the winners. Here are 19 of the best, including Tobias Friedrich's "Cycle War," the image named photograph of the year.
