subdivision = See text"Vorticella" is a genus of
protozoa , with over 100 known species. They are stalkedinverted bell -shapedciliate s, placed among theperitrich s. Each cell has a separate stalk anchored onto the substrate, which contains a contracilefibril called amyoneme . When stimulated this shortens, causing the stalk to coil like a spring. "Vorticella" mainly live in freshwater ponds and streams - generally anywhere protists are plentiful.Reproduction is by
budding , where the cell undergoes longitudinal fission and only one daughter keeps the stalk. The free daughter becomes atelotroch , which swims until it finds suitable substrate to fix and develop its own stalk.Other genera such as "
Carchesium " resemble "Vorticella" but are branched or colonial.Common species
