Eel Girl is a 2008 horror science fiction short film written and directed by Paul Campion, in which what appears to be a sort of human-eel hybrid woman, being studied by scientists in a Naval research facility, takes revenge on one of the scientists who is studying her.

He protests, quoting navy protocols that require two people to remain in the room at all times, but the officer makes sure he knows he has no choice.

Out of the darkness appears the Eel Girl, naked, her skin pale, with gills visible in her cheeks, and small fins on her forearms.

Suddenly her jaw extends and she shoves his head into her mouth, then lifts him into the air and swallows him whole, vomiting his shredded clothes.

She climbs back into the bathtub and lies there, caressing her now massively enlarged belly, and the scientist inside still alive.
