Crossing the Line

Would you like to be able to dodge a ball that was just about to hit you? If you could feel the wind rushing ahead of the ball from several feet away, you could. A shark has a sense called the lateral line that lets it feel movement in the water from many feet away!

Words to Know

lateral line:

Sharks and fish have a special line, called a lateral line, that runs along the sides of their bodies. This line is able to sense movement or vibrations in the water around the shark.

Try this experiment with a friend or your family to see what this feels like. Close your eyes and ask the other person to blow through a plastic straw or gently wave a paper fan at different places on your skin. Were you able to decide what object they used and where the air was moving across your body?

If youíve ever thrown a pebble in a pond and watched the circles from it move through the water, you have seen the rings of movement or motion. When a fish moves in the water, the shark can feel the same type of waves. Hundreds of sensors make up the sharkís lateral line. This line is located on the side of its body. It starts at its head and goes all the way to its tail. Fish that have backbones also have this same type of line. If you look at the side of a goldfish, you can see the line very easily.
