Jaws is a unique horror/thriller. Whereas in some movies the "monster" only comes out during the day, the antagonist in this movie preys whenever it wants, no matter the time of the day, in the ocean. In the beginning of the movie, the woman is eaten during dusk, whereas the majority of other attacks in the film takes place in the day. This shows that no matter what time of day it is, if you are in the water, you are not safe.
