Rotifera: A visual celebration of the smallest animals

Rotifera are tiny multicellular animals that are an amazingly important part of the food chain in most aquatic environments. They are the stepping stone in that food chain between bacteria and tiny algae particles and larger creatures, like insect larvae or filter feeders like ducks. Even being so small, they have eyes, a complete digestive system, and even a brain consisting of fifteen cells. Without these amazingly tiny wonders, the ecology webs of the world would collapse.
