Urotricha castalia (video)
Posted by sonntag
Urotricha castalia is a heterotrophic ciliate feeding mainly on small algae that appear simultaneously in lake plankton. In video ‚Urotricha castalia 1‘, we see the contractile vacuole in the posterior end of the cell and several elongated caudal cilia. In the video ‚Urotricha castalia 2‘, we see a squeezed individual with many intracellular bacteria (symbionts? […]

Uroleptus willii (video)
Posted by sonntag
Uroleptus willii is a ciliate thriving in lake plankton that can also build a mucous house, the so-called lorica. In the video, we see how U. willii feeds on bacteria or other small unicellular eukaryotes with its densely arranged ciliary bundles located at the tapering anterior. Characteristic for the species is that it lives in […]
