Natural horror is a subgenre of horror films that features natural forces,[1] typically in the form of animals or plants, that pose a threat to human characters.
Though killer animals in film have existed since the release of The Lost World in 1925,[2] two of the first motion pictures to garner mainstream success with a "nature run amok" premise were The Birds, directed by Alfred Hitchcock and released in 1963; and Jaws, directed by Steven Spielberg and released in 1975.
Following Jaws, numerous horror films of a similar narrative were produced, including Grizzly (1976), Piranha (1978), and Alligator (1980).
