Phytoplankton

Hello there. Can you see me? Probably not. I am super, super tiny, smaller than a little sprinkle on a cupcake. I float and drift in the big, blue ocean, soaking up the warm sunshine like a happy little flower. I sparkle in the water, but I'm so small that for a very, very long time, nobody knew I was here. I may be tiny, but I do a very big job for the whole world. Do you know who I am?

For ages and ages, people swam and sailed right past me. Then, way back in the 1670s, a curious man named Antonie van Leeuwenhoek used a special looking glass called a microscope to look at a single drop of water. And guess what he saw? Me. And millions of my friends, wiggling and floating. It was like he discovered a secret, underwater world. It wasn't until 1887 that another scientist, Victor Hensen, gave my family a name. He called us Phytoplankton. That means 'wandering plant,' because we drift wherever the water takes us.

So what is my big job? I make fresh air for you to breathe. When I soak up the sun, I breathe out the oxygen that fills your lungs and helps you run and play. I am also a yummy snack for tiny sea animals, which helps feed all the fish and even giant whales. Even though you can't see me, I am always here, working hard to keep our planet healthy and blue. Next time you take a big, fresh breath of air, you can say thank you to me, your tiny ocean friend.
