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.
