Paramecia refers to either an individual cell of the Paramecium genus of unicellular ciliated protozoans, or to a non-mineralized Ediacaran alga with a differentiated, compartmentalized thallus. This alga probably had multiple phases in its lifecycle, as possible reproductive structures have been identified.[1]
The use of "Paramecia" to mean a single ciliated cell, is more likely to be found, because the word was coined in 1752,[2] and so has a much longer history of use in this sense; and because its use as a model organism has created an enormous literature of this use.[3] One researcher has characterized it as the "white rat" of the phylum Ciliophora[4]
