Description
Interphase contrast light micrograph of a Spirostomum sp. ciliate protozoan. These single-celled organisms are found in freshwater and marine habitats. They feed on bacteria and decaying organic matter, which they filter through membranes in their primitive mouths called buccal cavities. The membranes, rows of fused cilia (short microscopic hairs), are also used for locomotion. Magnification: x240 when printed at 10 centimetres wide.
