Return to main Ciliophora page. Paramecium are the most commonly observed protozoans and, depending on the species, they are from 100-350 um long. They are easily maintained and cultured and Paramecium caudatum (shown at the left) are characterized by a large macronucleus and a single compact micronucleus.
Paramecium are heterotrophs. Their common form of prey is bacteria. A single organism has the ability to eat 5,000 bacteria a day. They are also known to feed on yeasts, algae, and small protozoa. Paramecium capture their prey through phagocytosis.
