Polarised light micrograph of Epistylis sp. protozoa. They are sessile, meaning they cannot move around on their own and need to attach to a surface. They are a common parasite on fish, binding to their scales or gills and producing red sores. They have a short oral disc for feeding and a rigid stalk. Magnification: x330 when printed 10 centimetres wide.
