Sperm and other microscopic organisms don’t have an easy time traveling from Point A to Point B. When an organism is that small, traveling just one inch is actually an incredible undertaking because they’re fighting against much more resistance. So how do they do it?

The fascinating TED-Ed video below explains the science behind how sperm and many other microscopic organisms are ultimately able to travel great distances relative to their tiny size. This video will change the way that you think about sperm and how they move. A lot of people picture them simply waving their tails back and forth, but the actual movement they make is far more complex than that. Check out the full video to learn more.
