Paramecium bursaria - this species of Paramecium is squatter than the more familiar ‘aurelia’ or ‘caudatum’-like species, and is also distinguished because it contains symbiotic green algae. The light structure to the left of centre is the opening to the mouth. Phase contrast micrograph. These images were taken of protozoa among marginal debris in the slow moving freshwater stream at Audley in New South Wales Australia by Feng Wie-Song and D. J. Patterson.

Paramecium bursaria

From the collection Audley Bottom

Description of Paramecium bursaria: Cell foot-shaped rather than elongate, the anterior is transversely truncated, the posterior rounded. Attains 80-150 microns long. The oral groove is very wide for most of its length. This species is easily recognised by the presence of green zoochlorellae in the cytoplasm. There are two contractile vacuoles with radiating collecting canals. There is a single, ovoid macronucleus and one elliptical micronucleus.
