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. The paramecium is larger than the ameba. It can be found in ponds with scum on them. It has more of a shape than an ameba, looking like the bottom of a shoe. It is covered with tiny hairs that help it move. These hairs are called cilia. The paramecium is able to move in all directions with its cilia. The paramecium eats tiny algae, plants, etc. The cilia propels the food into a tiny mouth opening of the paramecium. The food is then shoved down a little tube called a gullet that leads to the protoplasm or stuffing of the cell.
