Paramecium tetraurelia is a unicellular eukaryote (~120 micro m in length) that is used to represent the ciliate phylum. This phylum is characterized by cilia on the exterior of the organism which provide for locomotion and the capture of food.

Ciliates have dimorphic nuclei; the large nucleus, called the macronucleus, operates the somatic function and the micronuclei are required for sexual reproduction as they contain the germinal DNA. When moving through the water, paramecia rotate on the long axis producing a spiral motion through the water. When an obstacle is encountered they exhibit an avoidance reaction, backing away at an angle and starting off in a new direction.

Paramecia feed on microorganisms like bacteria, algae, and yeasts. Cilia sweep the food towards the oral groove, where it is ingested into food vacuoles. Enzymes from the cytoplasm digest the food as the vacuole makes its way to the anal pore where undigested food is expelled.

The Paramecium genome has diploid micronuclei and highly polyploid macronuclei (the exact level of ploidy is unknown). The genome is approximately 87 Mb in size, and has gone through at least three successive whole-genome duplications. It is predicted to have 39,642 protein-coding genes.
