An edoparasite is a type of parasite that lives inside the host organism, often within its tissues or cells. Unlike ectoparasites, which reside on the surface of the host, edoparasites can have a more intimate relationship with their host, potentially affecting its health and development. Common examples include certain species of worms and protozoa that invade the bodies of animals or plants. These parasites can cause various diseases and impact the host's overall fitness.
