Myxosporea are tiny creatures that have a special way of living. They live inside other animals or creatures, like fish, and make them sick. They are very small, so you can't see them without a special tool called a microscope.
When a fish or other animal gets infected with myxosporea, these tiny creatures make little spores, like seeds, that can spread to other fish or animals. The spores infect the fish and make them very sick, which can cause them to die if they don't get better.
Scientists are studying myxosporea to try to find ways to help fish and other animals that get infected. They want to find ways to prevent the spread of the spores and to keep fish and other animals healthy. They also want to learn more about how these tiny creatures work, so they can better understand the world around us.
