I was at a swim meet for Masters Swimming at Edgewater Beach in July, when I found a crazy shell on the beach. It was as big as my pinkie and looked like a heart. It was black, brown, and gray. My mom told me that it was a zebra shell. I lost the shell but I drew a picture of it.
When we got home, we decided to find out more about zebra mussels. As scientists, we began to ask a bunch of questions. My first question was about what zebra mussels eat. I was curious about this question because I am always hungry.
What do zebra mussels eat?
I found out from the University of Wisconsin Sea Grant Institute, that zebra mussels eat plankton. Plankton are tiny creatures that are microscopic. Plankton are a type of protozoans. I was curious about what they looked like, so I looked up a picture of plankton. This is what I found.
