Definition
'Phylum Rotifera' refers to a group of microscopic or near-microscopic animals known as wheel animals. They possess a unique ciliated structure called a corona, which resembles a rotating wheel, used for feeding and locomotion. Rotifers are primarily freshwater organisms. They play a significant role in aquatic food webs. They are diverse and abundant in many aquatic habitats. Think of them as tiny, bustling communities within a drop of water. π§
