The ocean is one of the world's last great frontiers and a source of endless fascination to children. In this vibrantly illustrated, interactive book, young readers take a safe deep-sea dive into the fascinating realm of Australia's Great Barrier Reef! Future oceanographers follow the trail of some of the most magnificent creatures on earth, including the powerful gray reef shark, the graceful yet deadly man-of-war, and the paralyzing blue-ringed octopus. To add to the fun, the book includes 64 pieces to assemble all eight of the animals profiled, with an exquisite removable diorama providing a realistic backdrop.
