Beneath the surface of the ocean lies a mysterious and astounding world that few people ever get to see. This book merges breathtaking art with the latest scientific research to take readers on a fantastic voyage on the submarine Marine Snow, where they meet blue whales, vampire squid, viper fish, and a giant sea spider. They'll learn about bioluminescence, Radiolaria, and coral reefs, and discover incredible facts about the marine world. Annika Siems's illustrations vibrate with color and detail, even as they convey the mystery of a place with scant natural light. From the smallest plankton magnified by thousands, to the most enormous whale, captured on a single page, the sea's denizens are recreated with spectacular precision and artistry. Marine biologist Wolfgang Dreyer's text brings the ocean to life-whether he's describing a transparent jellyfish or the way colors disappear from view as you descend to the ocean floor. A feast for the eye and the mind, this stunning book helps us comprehend a massive, mostly unfamiliar part of our world-one that flourishes with life and beauty.
