"Travel deep into the ocean way below the surface and you'll encounter some creatures you never knew existed! This book takes you on a journey through the dark depths of the sea towards the ocean floor. Most ecosystems need sunlight, but deep in the ocean where the sun doesn't shine animals have adapted some very interesting ways to see, protect themselves, and eat. Discover the unique habitats, adaptations, and food chains of these deep-sea creatures"--Amazon. com.
