Protozoa: a now obsolete term that referred to colorless protists and included flagellates, ciliates, amoebae and sporozoa. The protozoa were all thought to be single celled eukaryotes. The concept was popular for much of the 20th century, but it has become clear that some are relatives of animals and fungi, others have closer relationships with algae than with other protozoa, and that protozoa are not closely related. The term has largely fallen into disuse.

traduction de l'anglais http://eol.org/data_objects/3715435 :
Les protozoaires: un terme obsolète qui fait référence à protistes flagellés incolores et inclus, ciliés, les amibes et les Sporozoa. Le protozoaires ont tous été pensés pour être des eucaryotes unicellulaires. Le concept était populaire pendant la majeure partie du 20e siècle, mais il est devenu évident que certains sont proches des animaux et de champignons, d'autres ont des relations plus étroites avec les algues qu'avec d'autres protozoaires, et que les protozoaires ne sont pas étroitement liés. Le terme est largement tombé en désuétude.
Du grec ancien : « Proto » = « premier » + « zoa » = « animal »
désigne les protistes hétérotrophes qui ingèrent leur nourriture par phagocytose

Cellulose digested for fuel: protozoans
Mixotricha protozoans digests cellulose for termite metabolism.
"Termites harbor in their digestive system protozoa called mixotrichs that are critical to their ability to get energy by digesting cellulose." (Vogel 1998:29)

Microscopic oars move organism: protozoan
Bundles of microtubules projecting from the microscopic Sticholonche zanclea move the protozoans along through a rowing motion.
"At least one odd actinopod, heliozoan protozoan, Sticholonche, rows along with oars made of bundles of microtubules that emerge from the nuclear membrane through microfibrillar oarlocks. These form the central axes of external cytoplasmic protrusions--oars of a sort (Cachon and Cachon 1978; Margulis and Schwartz 1998)." (Vogel 2003:450)
