Diagram and label of polystomum integerrimum?

Polystomum integerrimum is a type of parasitic flatworm, specifically a monogenean, that typically infects the gills of fish. A diagram of this organism would typically include labeled parts such as the posterior attachment organ (haptor), which is used for attachment to the host, the body or trunk, and the reproductive structures, including male and female reproductive organs. Additionally, labels for the oral sucker, which is used for feeding, and the excretory system may also be included. This structure is crucial for understanding its Biology and life cycle as a parasite.
