Woman with a Toothed Vagina

This is a monster, presumably with "vagina dentata" (see below). She was possibly mentioned in the novel but did not appear in the film.

Origins

"Vagina dentata (Latin for toothed vagina) describes a folk tale in which a woman's vagina is said to contain teeth, with the associated implication that sexual intercourse might result in injury, emasculation, or castration for the man involved.

Several folk tales exist, with one notable example being Menmendas, a creature that looks like a beautiful young woman with spikes on her thighs. She walks in the coastal mountains with a small box of jewels and attracts every man on her way. Menmendas goes with an attracted man into an empty house, puts the box of jewels under her head and lies down with spreading legs. If the man understands who this woman is, he can cast a fistful of sand in her eyes and run away with the box. If the man gets attracted and turned on, the woman gathers him into half-and-half by her legs..."
