Caption: Floscularia rotifer feeding. Light microscope footage of a Floscularia ringens rotifer feeding. This rotifer has wheel-like lobes around its mouth, which are covered in hair-like cilia. Rhythmic beating of the cilia creates a current that wafts small particles into its mouth. F. ringens can reach a length of about 1.5 millimetres. It is widespread in freshwater environments. It makes a tube of small pellets (brown), with each pellet being made from dead bacteria and other detritus. It uses this tube to attach itself to a substrate, often submerged leaves, retreating into it when threatened. The shifting focal plane highlights the lobes, and some of the food particles, and also the beads in its tube.
