Dysteria (dist-ear-ee-a) is a hypostome ciliate. Like other hypostomes it favours particular food such as algae. The cell on the right has eaten blue-green (bacterial) algae and red (purple) sulphur bacteria. They can pick up their food using a jaw system made of stout rods capped with teeth. Cilia in this genus are restricted to a broad band running along the lateral margins of the cell. there is also a collection of cilia that form a podite - or attachment structure. This species is distinctive because it contains numerous green symbiotic algae. Differential interference contrast.  This picture was taken by David Patterson and Michele Burford of material from a commercial prawn farm in Queensland, Australia in 2000. Image copyright: D. J.
