The organism described possesses a protective lorica typically adorned with numerous spines, which can vary in color from yellowish to dark brown due to ferric hydroxide and a brown manganic compound. It features a single long flagellum extending from the anterior aperture, often surrounded by a thickened collar. Chromatophores may appear as two curved plates or multiple disc-shaped structures, while paramylum bodies are small grains. Additionally, it has a stigma and pyrenoid. Reproduction occurs through fission, where one daughter cell retains the lorica and flagellum, while the other escapes to form a new lorica. Cysts are commonly formed, and this organism is typically found in freshwater environments. The morphology of the lorica serves as a crucial taxonomic characteristic, with variations in shape, size, color, and surface ornamentation documented across different studies.
