The deep sea is the biggest, most mysterious part of our living planet. For a long time, scientists thought this was just a huge empty space and nothing lived down there, because it's too dark, too cold, there's too much pressure, and not enough food. Now we know the deep sea is full of amazing life all the way to the very bottom. To survive down there, animals get up to all kinds of strange things and look completely different from anything else on Earth. Written by award-winning marine biologist and author Dr. Helen Scales, and printed with a fifth silver pantone throughout, The Deep, Dark Ocean comprehensively visualizes the deep ocean environment and brings its beautiful and unbelievable quirks to life. Readers find themselves immersed in the velvety dark landscapes of deep-sea plains, trenches, and mountain ranges, and discover ghostly octopuses, sea pigs, dancing crabs, coral, and sponge forests, Elvis worms, and Ninja lanternsharks, among other remarkable creatures.
