Description
edit_(20100491984).jpg)
The cell body of Bursaria is scoop-shaped, and can be up to 1 mm long. Their oral region is crescent-shaped, and there is a band of membranelles (compound structures composed of multiple cilia) leading into the mouth. They live in the plankton of freshwater environments and ingest other protists, including algae and other ciliates.[1] Bursaria are the largest-sized colpodean ciliates.[2]
Systematics
editBursaria is the sole genus in the family Bursariidae.[2] The genus was originally described by O. F. Müller in 1773, with B. hirundinella as the type species.[3] It was formerly classified as a heterotrich, but is now classified as a member of the class Colpodea, based on the development of its oral structures (stomatogenesis) and its ultrastructure.[2]
