Vorticella contraction, light microscopy

Videonummer 11944208
Vorticella contraction. Light microscopy footage of Vorticella campanula, a ciliate protozoan, feeding and displaying its startle response. The clip starts with a close-up of the bell-shaped head and peristome (opening) that is lined with two rows of cilia. The ciliary movements cause a water current that carries microscopic algae, bacteria and other food into the buccal cavity (infundibulum). At the end of the clip, the startle response is seen, where contraction of the stalk (myoneme) pulls the protozoan downwards out of sight. Vorticella live in both marine and freshwater environments. This is a freshwater specimen.
