Book excerpt: For over 400 million years, sharks have been the ocean's top predator! They're vital to our ecosystem, but their importance is often overshadowed by our own fear—even though they hardly ever threaten humans. Dive in for an intimate look at the dynamic hammerhead, infamous great white, primordial megalodon, and the gentle nurse shark, the rare species that will let a scuba diver pet them! This book is filled to the gills with jaw-dropping illustrations and razor-sharp facts that shed light on these fascinating creatures of the deep, including their undersea terrain, cunning adaptability, and staggering variety. Every volume of Science Comics offers a complete introduction to a particular topic—dinosaurs, coral reefs, the solar system, volcanoes, bats, flying machines, and more. These gorgeously illustrated graphic novels offer wildly entertaining views of their subjects. Whether you're a fourth grader doing a natural science unit at school or a thirty year old with a secret passion for airplanes, these books are for you!
