Description
Rotifers have a characteristic circular arrangement of cilia at their front ends. These cilia are used to bring food particles, including bacteria, debris and small protozoans, towards the mouth.
A mastax, a jaw-like structure, grinds the food as it enters the stomach. Excretory structures known as
flame cells create a current that drains them into the intestines or the bladder.
They have transparent bodies and two strong structures that are used for swimming. They are sheathed in a glassy shell secreted by their outer skin.
