Culturing Chilomonas

Chilomonas are free-living, freshwater protozoans. They inhabit water littered with decaying plant matter like stagnant ponds, ditches or marshes. These protozoans are unable to photosynthesize because they lack chloroplasts, or chromatophores, which are pigment containing structures. They commonly feed on organic matter and are often consumed by other protists such as Amoeba and Paramecia. Chilomonas are extremely tiny, usually reaching 20–24 microns in length, which is below the limits of visibility to the naked eye. Two flagella extend from their anterior giving the Chilomonas excellent locomotion.

Feeding Paramecia

Look through the transparent cell membrane of a one-celled organism, Paramecium, as it ingests yeast cells. You’ll be amazed at what you see!

Dichotomous Key to Flinn Protozoa

This simple dichotomous key and its accompanying drawings are included to assist students in identifying common protozoans normally found in our cultures. It is suggested that methyl cellulose solution (Flinn Catalog No. M0155) be used as a slowing agent for fast moving protozoans.

Protozoa Exceed the Speed Limit!

Protozoa, especially the ciliated form, often move too quickly for beginners to follow their movements under the microscope. Here’s how to slow them down!
