Dr. Universe: How can fish see in the water? – Dottie, 7, South Dakota
Dear Dottie,
When I was little, I learned to swim by diving for coins in the pool. It wasn’t easy seeing the coins underwater. It was blurry down there.
I talked about how fish see with my friend Nora Hickey. She’s a fish veterinarian at Washington State University.
She told me that fish eyes don’t work the same way mammal eyes do – even though we have the same eye parts. |

Your cornea is the clear, squishy tissue right at the front of your eye. It’s in front of the colored ring in your eye – called the iris. There’s a dark dot in the center of your iris – called the pupil. It gets bigger or smaller depending on how much light there is. Your lens is deeper in your eye, behind your pupil. The very back of your eye – called the retina–has lots of nerve cells that connect to your brain. |
