The water strider is classed as a true bug (a member of the Gerridae family) and lives on or around the surface of freshwater. Despite being denser than water, it can skate across the surface without breaking through. Its feet bend in such a way that the water deforms, much like elastic film thanks to tiny hairs that trap air bubbles between them and the water’s surface. Its middle legs act as paddles, making movement possible, while its long rear legs enable it to steer and even brake as it glides across the water. Its front legs are also short enough to grab prey – living or dead – along the way. Thankfully, the speed at which the water strider can move means it stands a chance against its own predators.
