Explains the basic principles of movement of vertebrates and insects: swimming, running and walking, flying and gliding, and undulating or wriggling.In this book I am going to try to tell you how far such impressions are true, and to help you to watch moving animals ... We all know that a car, with its engine switched off, will not start to move over a level surface by itself: to make it move we have to push it with our hands (Fig. i). We can only push it with our hands if, at the same time, we give an equal and opposite push against the ground with our feet.
