Taxonomy
While some work has been done to erect a more distinct classification above the genus level for Multicilia marina,[2] the placement in Amoebozoa remains.[3]
Etymology
Multicilia marina derives its title from the Latin "marinus," meaning "of the sea", and from having multiple
Ecology
Multicilia marina has been observed interstitially in brackish biotopes, between grains of sand and marine debris. The organism is heterotrophic and feeds on naked amoebae.[2]
Morphology and behavior
Multicilia marina can come in a variety of shapes, which are primarily attributed to the varying salinity of their environments; most are round with between twenty and thirty weak cilia, and they have no polarity. Some tetraflagellar forms can be found, in which there is a central nucleus. In this form, two of the flagella are anterior and functional, while the other two are lateral and have no function. Multicilia marina can also take a

History of knowledge and taxonomy
Multicilia marina was first isolated by Leon Cienkowski in 1880 in the White Sea, where it has been found numerous times since, and then by Mylnikov in a brackish biotope of the Baltic Sea. It has been isolated in more recent years in the brackish waters of the Gulf Coast.[2]
Multicilia marina formerly had the classification as a distinct phylum Multiflagellata or lobose amoebae. It is now known that Multicilia marina is an amoeba, branching at the base of Conosea. In 1881, Cienkowski proposed that Multicilia marina lie somewhere between flagellates and heliozoans, based on morphological characteristics. In 1954, Kudo proposed that they were a part of the order Rhizomastigina. From 1996 to 1998, the discovery and documentation of flagellar differences between members of Rhizomastigina and Multicilia marina led to the creation of a new phylum: Multiflagellata. From 1998 into the early 2000s, Cavalier-Smith placed Multicilia marina in the phylum Amoebozoa, claiming that the genus was related to Archamedae and Vanellidae.[1]
No related taxa or ancestors can be identified based on current research. Species within the genus Multicilia include marine Multiciliate marina, discovered by
