Differential interference contrast light micrograph of a Vorticella sp. ciliate protozoa. Vorticella are mostly 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 of any species. Magnification: x550 when printed at 10 centimetres wide at its longest edge. | |
