Thuricola and Vorticella ciliates

Référence de la vidéo 11936623
Thuricola and Vorticella ciliates. Light microscope differential interference contrast (DIC) footage of the peritrich ciliates Thuricola folliculata (green, elongated) and Vorticella (bell-shaped). These sessile microscopic organisms are found in water, attached to other plants and animals by a stalk. Thuricola folliculata houses symbiotic green algae (genus Chlorella), and has a shell-like protective chitinous outer covering (a lorica), with a flap valve. On disturbance, the ciliate retracts into its housing. The Vorticella ciliates similarly contract their stalks for protection. These retractions are seen several times here. Magnification: x71 at 10 centimetres across.
