For a planet that’s mostly water, we spend a lot of time on land. Our oceans are home to creatures that haven’t yet been discovered, and natural formations that are yet to be found. Get to know the deep blue a little better with these incredible photos of glowing jellyfish and billowing octopus from the Underwater Photographer of the Year Awards. There are a hundred winning images—these are our favourites.
