=== Physiology === The creation scene in James Whale's 1931 film Frankenstein makes use of electricity to bring the monster to life. Shelley's idea of reanimation through electric shock was based on the physiology experiments of Luigi Galvani, who noted that a shock made the leg of a dead frog twitch. Electric shock is now routinely used in pacemakers, maintaining heart rhythm, and defibrillators, restoring heart rhythm. The ability to produce electricity is central to Naomi Alderman's 2016 science fiction novel The Power. In the book, women develop the ability to release electrical jolts from their fingers, powerful enough to stun or kill. Fish such as the electric eel, Electrophorus electricus, create powerful electric fields with modified muscles, stacked end-to-end as cells in a battery in their electric organs, and the novel indeed references such fish and the electricity generated in striated muscle.
=== Parasitism ===
Parasites appear frequently in fiction, from ancient times onwards as seen in mythical figures like the blood-drinking Lilith, with a flowering in the nineteenth century. These include intentionally disgusting alien monsters in science fiction films, though these are sometimes less "horrible" than real examples 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. Some fictional parasites, like the deadly parasitoid Xenomorphs in Alien, have become well known in their own right. Terrifying monsters are clearly alluring: writer Matt Kaplan notes that they induce signs of stress including raised heart rate and sweating, but people continue indulging in such works. Kaplan compares this to the "masochism" of liking very hot spicy foods, which induce mouth burns, sweating, and tears. The psychologist Paul Rozin suggests that there is a pleasure in seeing one's own body react as if to stress while knowing that no real harm will result. Some parasitic organisms in fictional works often have a Hive mind that they associate with. An example of this would be The Flood, from the Halo franchise.
=== Symbiosis ===
Symbiosis (mutualism) appears in fiction, especially science fiction, as a plot device. It is distinguished from parasitism in fiction, a similar theme, by the mutual benefit to the organisms involved, whereas the parasite inflicts harm on its host. Fictional symbionts often confer special powers on their hosts. After the Second World War, science fiction moved towards more mutualistic relationships, as in Ted White's 1970 By Furies Possessed, which viewed aliens positively. In The Phantom Menace, Qui-Gon Jinn says microscopic lifeforms called midi-chlorians, inside all living cells, allow characters with enough of these symbionts in their cells to feel and use the Force.
=== Ethology ===
Ethology, the study of animal behaviour, appears in the wildlife scientist Delia Owens's 2018 novel Where the Crawdads Sing. The protagonist, Kya, is abandoned by her parents at age six, and grows up alone in a North Carolina swamp, learning camouflage and how to hunt from the animals there. The local townspeople call her "the marsh girl". She reads about ethology including an article entitled "Sneaky Fuckers", using her knowledge to navigate the tricks and dating rituals of the local boys; and she compares herself to a female firefly, who uses her coded flashing light signal to lure a male of another species to his death, or a female mantis, who starts eating her mate's head and thorax while his abdomen is still copulating with her. "Female insects, Kya thought, know how to deal with their lovers."
=== Ecology ===
Ecology, the study of the relationships between organisms and their environment, appears in fiction in novels such as Frank Herbert's 1965 Dune, Kim Stanley Robinson's 1992 Red Mars, and Margaret Atwood's 2013 MaddAddam. Dune brought ecology centre stage, with a whole planet struggling with its environment. Its lifeforms included giant sandworms for whom water is fatal and mouse-like animals able to survive in the planet's desert conditions. The book was influential on the environmental movement of the time. In the 1970s, the impact of human activity on the environment stimulated a new kind of writing, ecofiction. It has two branches: stories about human impact on nature; and stories about nature (rather than humans). It encompasses books written in styles from modernism to magical realism, and in genres from mainstream to romance and speculative fiction. A 1978 anthology of ecofiction includes 19th and 20th century works by authors as diverse as Ray Bradbury, John Steinbeck, Edgar Allan Poe, Daphne du Maurier, E. B. White, Kurt Vonnegut Jr., Frank Herbert, H. H. Munro, J. G. Ballard, and Isaac Asimov.
=== Fictional organisms ===
Fiction, especially science fiction, has created large numbers of fictional species, both alien and terrestrial. One branch of fiction, speculative evolution or speculative biology, consists specifically of the design of imaginary organisms in particular scenarios; this is sometimes informed by precise science.
== Functions == Fictional biology serves a variety of function in film and literature, including the supply of suitably terrifying monsters, the communication of an author's worldview, and the creation of aliens for biological parables to illuminate what it is to be human. Real biology, such as of infectious diseases, equally provides a variety of contexts, from personal to highly dystopian, that can be exploited in fiction.
