Vorticellas eat bacteria and small protozoans and live in fresh or salt water attached to aquatic plants, surface scum, submerged objects, or aquatic animals.

How do the Vorticella feed?

These bell-shaped ciliates live in fresh or salt water attached by a slender, unciliated stalk to aquatic plants, surface scum, submerged objects, or aquatic animals. Vorticella eat bacteria and small protozoans, using their cilia to sweep prey into their mouth-like openings.

Is a Vorticella a Heterotroph?

Vorticella are heterotrophic organsims. They prey on bacteria. Vorticella use their cilia to create a current of water (vortex) to direct food towards its mouth.
