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. The tip of one of these rods can be seen inside the cell at about 1 o clock from the centre of the cell. 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. Differential interference contrast.  This picture was taken by David Patterson, Linda Amaral Zettler and Virginia Edgcomb of material from the salt marsh at Little Sippewissett (Massachusetts, USA) in Autumn, 2000 and in Spring and summer, 2001.
