Water Strider
As with all insects, the water strider has three pairs of legs. The front legs are much shorter, and allow the strider to quickly grab prey on the surface. The middle legs act as paddles. The back legs are the longest and provide additional power, and also enable the strider to steer and “brake.”
The buoyancy and paddling legs allows striders to be fast. Very, very fast. The National Geographic article reports striders are capable of “speeds of a hundred body lengths per second. To match them, a 6-foot-tall person would have to swim at over 400 miles an hour.” from Cool Green Science.
