Shelob is a fictional demon 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.
Oonopidae, also known as goblin spiders, is a family of spiders consisting of over 1,600 described species in about 113 genera worldwide, with total species diversity estimated at 2000 to 2500 species. The type genus of the family is OonopsKeyserling, 1835.
Linyphiidae, spiders commonly known as sheet weavers, or money spiders is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution, new genera and species are still being discovered throughout the world. The newest such genus is Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
