These include intentionally disgusting alien monsters in science fiction films, often with analogues in nature. Authors and scriptwriters have to some extent exploited parasite biology: lifestyles including parasitoid, behaviour-altering parasite, brood parasite, parasitic castrator, and many forms of vampire are found in books and films.
