In the pond sample, ciliates were observed rapidly changing shape as they hunted bacteria.

Under the microscope, the ciliate protozoan used its hair-like structures to navigate toward food.

Under the microscope, the ciliate darted across the slide, its rows of beating cilia shimmering like tiny oars.

The ciliated cells in the respiratory tract help move mucus out of the lungs.

The researchers measured ciliation of the epithelial cells to determine how effectively they could clear mucus.

The biologist cataloged the ciliations on the epithelial samples under the microscope.
