Salpingoecidae

Salpingoeca rosetta

The Salpingoecidae are a taxon of the so-called collar flagellates. The taxon includes six genera.

Features

All species are living separately or as a colony of cells, free-floating or sedentary. A stem may be present or absent. The case, known as the theca, is a Periplast, which is clearly seen by light microscopy.

The very pronounced collar protrudes laterally around the neck of a single flagellum, which, however, can also be omitted. Freshwater forms have at their rear end usually two, but occasionally on more contractile vacuoles.

Dissemination

Types of Salpingoecidae can be found in freshwater, brackish and sea water.
