Shelob

Shelob is a fictional monster in the form of a giant spider from J. R. R. Tolkien's The Lord of the Rings. Her lair lies in Cirith Ungol leading into Mordor. The creature Gollum deliberately leads the Hobbit protagonist Frodo there in hopes of recovering the One Ring by letting Shelob attack Frodo. The plan is foiled when Samwise Gamgee temporarily blinds Shelob with the Phial of Galadriel, and then severely wounds her with Frodo's Elvish sword, Sting.
