As a unicellular protozoa, Stentor can be up to 2 millimeters in size, making them visible to the naked eye. They live in stagnant freshwater environments and feed on bacteria. They move and eat through the use of cilia, and they maintain their water balance with the use of a contractile vacuole.

What is a Stentor locomotion?

Most notable of the stentor is the 'crown' of cilia surrounding the trumpet 'bell'. ... The crown is not the only cilia on the stentor, its whole body is covered with shorter cilia, which are used for locomotion when free swimming. When moving, the stentor is contracted into an oval or pear shape.

What makes Stentor unique?

Stentor is remarkable for its regenerative powers; a small fragment less than one-hundredth of the volume of an adult can grow back into a complete organism. This capability has made Stentor a favourite subject for studies of regeneration in protozoans.
