More Ciliates of the Madog River Water

drawings by Brenna Lorenz
Drawing of a paramecium  Paramecium is one of the most famous of the freshwater ciliates. These large, lively tan protozoans are abundant in Madog River water.

Sketch of a Vorticella  Vorticella are another common Madog River ciliate. These lively bell-shaped protozoans are normally attached to debris, but we also find them swimming around loose, trailing their stalks behind them. There are two different species. One is as pictured here, and the other is larger, with a wider,  flatter bell.

Drawing of Frontonia, also depicting conjugating Frontonia.  Frontonia are impressively large, or can be, although they show considerable variation in size. They are one of the most common of the Madog River protozoans, especially early in the history of the culture.

Drawing of 2 kinds of Stentors  In addition to the aqua stentor shown on the main page, we also have been finding an increasing number of colorless and light brown stentors, shown here.

Drawing of Loxodes  The lively Loxodes were actively engaging in conjugation during my last visit.

Drawing of Prorodon, including a sketch of Prorodon dividing.  These dusty-looking Prorodon ciliates showed up with the amoeba after most of the other ciliates were past their prime.

Sketch of a mysterious ciliate.  This comical-looking ciliate has long, floppy cilia. While swimming, it tumbles wildly. Periodically, the ciliate stops moving completely for a few seconds. During these rest periods, it is possible to observe its shape and the distribution of its cilia. We have not been able to figure out what kind of ciliate this is.

Drawing of Opisthonecta, showing scrunched and extended phases.  There was a sudden bloom of these funny barrel-shaped ciliates.
