We are huge fans of this series at BooksForTopics HQ. Take a dive through the different layers of the ocean to the deepest trenches below with our favourite feline scientist, Professer Astro Cat. Each double-page spread offers a highly visual array of facts themed around a different stage of the sea voyage. Starting with fun on the seashore (did you know that most of the white sand in Hawaii is actually parrotfish poop?), we then join Professor Astro Cat as he boards a sea vessel and takes a crash course in navigation and ocean weather. The animals don their diving gear and explore the kelp forests and continental shelf of the shallow zone (find out how the torpedo ray can kill small fish with a 200-volt electric shock) before progressing deeper to discover a host of creatures including sharks and cephalopods. Going deeper still, Professor Astro Cat explores how the bigger and smaller creatures are connected via the food web before heading into the very darkest zones and deepest trenches (where you’ll find out how zombie worms got their name). Every page is highly visual down to the tiniest detail and the selected information is at once interesting and informative, allowing readers to delight in their newfound knowledge and quickly feel like an expert. The book is well suited to children in terms of reading level, design style and interest range.
