Explaining Nature on Instagram: "Rotifers are microscopic, mostly freshwater animals that belong to the phylum Rotifera. They are called “wheel animals” because they have a distinctive ciliated structure at their head end, called a corona, which looks like spinning wheels under a microscope. The cilia beat in coordinated waves to draw food (mainly algae, bacteria, and organic particles) into their mouths and to help them swim. • #reels #explore #nature #viral #interesting #learn #science"
