These rotifers are commonly found in freshwater environments and play a significant role in the local microbial community. Measuring around 100 micrometers on average, they are too small to be seen without a microscope, but their intricate details are revealed when magnified. Enclosed within a protective shell consisting of two closely joined plates, their bodies feature a distinctive concave contour along the anterior edges, resembling a C-shape. At the bottom of their bodies, there is a movable foot with two toes of equal length, used for both attachment and locomotion. Their nutrition is obtained through a rotatory apparatus equipped with cilia, which creates a water vortex to capture organic food particles such as small protozoa, algae, and bacteria. This apparatus also aids in their movement over significant distances. Some rotifers can enter extended cryptobiosis, remaining dormant for thousands of years. They exhibit sexual dimorphism, with observable differences between females and males. Young individuals develop inside eggs laid by fertilized females.
