Explaining Biology on Instagram: "This mesmerizing microscopic view reveals a rotifer, a tiny aquatic organism known for its remarkable feeding structure called the corona. 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
