Choreotrichea

Choreotrichea is a class of protists that includes the diplomonads and parabasalids. These organisms are characterized by their unique flagellar apparatus, which consists of a single basal body and a single flagellum. The flagellum is typically used for locomotion, and the basal body is often located at the base of the flagellum. Choreotricheans are found in a variety of environments, including freshwater, marine, and soil. They are often parasitic, feeding on other protists or small animals. Some species are also known to be symbiotic, living in close association with other organisms. Choreotricheans are important in ecological and evolutionary studies due to their unique biology and the role they play in various ecosystems.
