Eric is seen with an open shirt twice.

Ariel is seen naked when picked up from the ocean (she covers herself with her hair and her legs so nothing graphic is seen), we see her later in the tub (again everything is covered).

Vanessa, wears some revealing clothing in her room (very brief).

The mermaids' midsection is revealed and the mermens' chest and shoulders are bare.

Scuttle and Sebastian attack Vanessa aggressively right before her and Ariel physically fight.

At least one use of the phrase "oh my god" towards the start of the climax.

Two uses of "idiot", one use of "stupid" and one use of "shut up".

Sailors are briefly seen drinking during a party on board.

Vanessa is very intense and scary. She even fights Ariel briefly at one point and pins her down.

Ursula can be unsettling and creepy.

Flotsam and jetsam are creepy eels

Ursula is kind of harassing Ariel for her voice. Very creepy and unsettling lead up.

Ariel and Triton fight a lot and have a bad relationship

Ursula has a creepy laugh that is heard throughout the movie

Ursula's area is creepy. It's deep underwater, and when you enter a bunch of dead mermaids are seen. Theres also creepy animals at the entrance with 1 eye.

When Triton gets mad he destroys everything of Ariel's.

A shark attacks Ariel in the beginning while she explores a shipwreck. She gets away, but it's scary.
