Salpingoeca: A Choanoflagellate

Rights-Managed, Footage

Location and time:

Germany, Düsseldorf, 2010


This protist is called Salpingoeca. It is sitting in a hyaline lorica, has one contractile vacuole and on top of the cellbody there is a weir, a kind of funnel, with a single, long flagellum in the middle. It is said to be a precursor of the marine sponges: S. belongs to the class of Choanoflagellatas. Choanoflagellatas are related to Choanocytes. These Choanocytes are found in all sponges and look and work like a Salpingoeca; especially the system weir - flagellum is very similar. Choanocytes in a sponge are doing the job of water-filtering for food, e.g. plankton, bacteria and detritus (organic waste).
