Vorticella

Genus Vorticella

Fascinating Facts

They have cilia on their oral end and a contracting stalk on the other.
The stalk contracts in a corkscrew shape as a defense mechanism.
Vorticella feed on bacteria and small protozoans.
If food is scarce, they can detach themselves to find a new location.

Form and Function

Single-celled, stalked, bell-shaped microorganism.
Live in fresh or salt water attached to aquatic plants, surface scum, submerged objects, or aquatic animals.
Congregate in large colonies, but each vorticella stays independent.
