In case you needed further proof that the ocean is a bizarre, magnificent and totally alien world, the Underwater Photography Guide has announced the winners of its 2015 Ocean Art Underwater Photo Competition.

The photo submissions, which come from more than 50 countries and include ocean as well as freshwater scenes, capture “out-of-this-world fish and marine life shots, rarely seen underwater behavior, cute portraits, dreamy scenes in the conceptual category, sharks, whales and some dramatic moments between humans and marine life,” the publication said in a release.

The “Best of Show” winner, for example, is a photo of a larval-stage eel spotted at night off the coast of Hawaii’s Big Island. The creature, UPG wrote, “looks like an alien invader from outer space, and has only been photographed a handful of times before.”

The rest of the first-place photographs show equally impressive scenes, proving yet again that the ocean is a chaotically beautiful place. Below, you can see some of the winning photos, along with the photographers’ own accounts (which originally appeared at UPG) of how each picture came to be.
