The yolk then moves into the oviduct, a long tube where the rest of the egg forms. In the first section, the egg white (albumen) is added. This thick, clear liquid surrounds the yolk and

The corona appears to rotate, but in reality, it is made of rapidly beating cilia that create powerful water currents. These currents pull in food particles such as algae and bacteria, guiding them toward the rotifer’s mouth with incredible precision. Beyond feeding, the corona also helps the rotifer move through its watery e
