From The Collaborative International Dictionary of English v.0.44 [gcide]:
Protozoa \Pro'to*zo"a\, noun pl. [NL., fr. Gr. ? first + zo^,on an animal.] (Zo["o]l.) The lowest of the grand divisions of the animal kingdom.
Note: The entire animal consists of a single cell which is variously modified; but in many species a number of these simple zooids are united together so as to form a compound body or organism, as in the Foraminifera and Vorticell[ae]. The reproduction takes place by fission, or by the breaking up of the contents of the body after encystment, each portion becoming a distinct animal, or in other ways, but never by true eggs. The principal divisions are Rhizopoda, Gregarin[ae], and Infusoria. See also {Foraminifera}, {Heliozoa}, {Protoplasta}, {Radiolaria}, {Flagellata}, {Ciliata}.
