Paramecium 2 
Paramecium 2

In this picture you can see the long opening called the oral groove, which acts as a mouth. When food is directed in through the groove, it is engulfed into food vacuoles, which are tiny digestive systems, sort of like temporary stomachs. Excess water is collected into a contractile vacuole, which periodically contracts to empty the water out of the cell. The cell also has a macronucleus, a micronucleus, trichocysts, and an anal pore. And that's about all you need to be a succesful protozoan!
