A paramecium is a small one celled (unicellular) living organism that can move, digest food, and reproduce. They belong to the kingdom of Protista, which is a group (family) of similar living micro-organisms. Micro-organism means they are a very small living cell.

They are about .02 inches long (.5mm). They are also famous for their predator-prey relationship with Didinium.
