Peritrichia

[taxonomy:genus=Vorticella] Date: 23 Aug 2011 Location: Small lake in Kent Ridge Park. Water margin with vegetation, brown sediment with organic detritus. Tadpoles resting nearby. Microscope: Bright-field with closed condenser aperture. Camera: Nikon D7000 Collector: Brandon Seah Scale: 20830 pixels/mm = 20.8 pixels/µm

[taxonomy:genus=Thuricola] This is a ciliate living inside a vase-shaped "lorica", or shell, that comes with its own lid that shuts behind the cell when it retracts into its den. Unfortunately, my attempt to "tap on the glass" and have it retract were not successful. Note the streaming of particles in the water due to the feeding current set up by the cilia of the creature.
