Answer:

Rotifers (common name wheel animals) are microscopic aquatic animals belonging to the phylum Rotifera.

Explanation:

The most distinctive feature of rotifers is the presence of corona, which is a ciliated structure present on the head. This helps create a current that sweeps food into the mouth. The coronal cilia also help to pull the animal, when unattached, through the water.

Rotifers are an important part of the freshwater zooplankton. They feed on dead bacteria, algae and protozoans, thus contributing to nutrient cycling.

Rotifers are commonly found in freshwater environments. Some species are found in saltwater too.
