Readers take a dive underwater to take an in-depth look at the mechanics behind fish and other sea creatures. Marine creatures are made to fit their environments, whether they live in shallow reefs or the deep sea. This book describes the technology behind the super senses of sharks, the speed of a sailfish, and the propulsion of squid. How big are giant clams? How does a stonefish launch a sneak attack? Readers will learn the answers to these questions and more through fascinating text and fact boxes. Color photographs bring readers to the depths of the sea to come face-to-face with these mechanical wonders!
