Jaws is an American natural horror film series that started with a 1975 film that expanded into three sequels, a theme park ride, and other tie-in merchandise, based on a 1974 novel.
 The main subject of the saga is a great white shark, and its attacks on people in specific areas of the United States.
 The Brody family is featured in all of the films as the primary antithesis to the shark.
