A few uses of S-- and F--- word as well as Damn and Hell.

There is a little civilized drinking and Barbara smokes.

A central premise of the film is that humans are mating with undersea creatures producing the Deep Ones, half-human hybrid fish-frog people.

There are many intense scenes in this movie.

The entire film was shot to be intimidating and frightening in just the town itself, never mind the happenings in it.

There is an implied offscreen rape.

Human skin leather is seen in a warehouse and worn as masks.

There are several suicides.

There is an implied incest relationship.

There is a lot of cult and occult activity in this film.

The town is full of monstrous fish-men a lot creepier than the Creature from the Black Lagoon.
