Order Cilioflagellata is a group of unicellular organisms that possess both cilia and flagella for locomotion. This order was first described in 1878 by German zoologist Antón F. Doflein. Despite being a relatively obscure group, there are several synonyms for Order Cilioflagellata, which include Protociliata, Holotricha, Heterotricha, Phryganellina, and Peritrichida. Each of these synonyms refers to different characteristics of this group of organisms, such as their cilia structure, their shape, or their habitat. While the name may vary depending on the context, the properties of Order Cilioflagellata remain the same and are considered an important area of study in biology.
