Tetrahymena thermophila is a free-swimming ciliate that utilizes hundreds of motile cilia for hydrodynamic force-generation. One macronucleus, one micronucleus and one contractile vacuole are contained in the body. It has 7 sexes, and pairs of mating cells produce genetically identical progeny. Remarkably, every cell maintains differentiated germline and somatic genomes: one silent, the other expressed.
