Tetrahymena are non-pathogenic free-living ciliate protozoa. They are common in fresh-water aquatic habitats. Tetrahymena are pear-shaped and 30-100 μm in length, belonging among the hymenostomes and with cilia typical of that group. Most Tetrahymena thrive at temperatures of 18-22 degrees Celsius. Because of their short generation time and because they can be grown to high cell density in inexpensive defined media, they are ideal models for experimental biology and common subjects of scientific studies.

Tetrahymena - Wikipedia, the free encyclopedia (99 words)
Tetrahymena are ciliate protozoa, common in aquatic habitats.
They are pear-shaped and 30-100 μm in length, belonging among the hymenostomes and with cilia typical of that group.
Tetrahymena thrive at temperatures of 18-22 degrees Celsius.
Genetics (7567 words)
Tetrahymena (and most Ciliates) are remarkably advanced among unicellular eukaryotes: no cell reproduction in the haplophase; differentiation of somatic and germ line nuclei; binary fission in the face of highly specialized compound cell structures; conjugation in diplophase; and internal fertilization at conjugation.
The somatic ciliature in Tetrahymena is distributed throughout the cell and organized in a regular array of rows (or meridians) of ciliary units in the cell cortex [illustrated in ref. 2, p.180].
