When disturbed, the vorticella contracts and the stalk thread is shortened, causing the sheath to coil tightly like a spring.Phase Contrast illumination.

Ciliate feeding on sulphur bacteria

When disturbed, the vorticella contracts and the stalk thread is shortened, causing the sheath to coil tightly like a spring.Phase Contrast illumination.

The stalk is made up of an external sheath that contains a fluid and a spirally arranged contractile fibril called a myoneme that contracts when stimulated. When disturbed, the vorticella contracts and the stalk thread is shortened,...
