Creatures of the Deep takes readers on an incredible 3D journey through the depths of the ocean. With the use of pop-ups, fold-out landscapes and stunning illustrations, this interactive book reveals the strange but wondrous residents of this dark and inhospitable world. Each of the ocean's three zones - sunlit zone, twilight zone, and dark zone - is explored in turn, but the book's focus is on the deep ocean which begins some 200 m (600 ft) below the surface. Colourful, fact-filled pages reveal the ocean's dramatic deep-sea landscapes, the thousands of fascinating species that live there, the people who study them, and their latest spectacular discoveries. With details of ocean exploration, from early pioneers to modern-day research, and information on threats to this fragile habitat, Creatures of the Deep is a fun and engaging introduction to life at the bottom of the ocean.
