Vorticella protozoa. Darkfield illuminated light micrograph of a colony of Vorticella sp. ciliate protozoa. Vorticella are sessile, meaning they attach to a surface and cannot move around on their own. When disturbed, they contract their stalk into a tight coil. This contraction is one of the fastest known actions in the animal kingdom. Magnification: x36, when printed 10 centimetres wide. | |
