This image-rich BioMedia article features a micro-naturalist's observation of Vorticella isolated from a ditch on a country road. The article describes the appearance of Vorticella and details its behaviors. It also reports an experiment showing how clusters of vorticelloids form, and ends by addressing the question: What is the survival advantage of living in a group? This article is part of a series called "The Lives of Micro-organisms: A Micro-Naturalist's Notebook". The website also contains links to other articles and features of BioMedia, including a gallery of images and a teacher page with various downloadable teaching guides for BioMedia programs.
