Jorōgumo
A yōkai of Japanese folklore depicted as a spider-associated shapeshifter that can take the form of a woman to lure, entangle, and sometimes devour humans.

Jörmungandr
In Norse mythology, Jörmungandr is an unfathomably large sea-serpent, the Midgard Serpent or World Serpent, that dwells in the world sea and encircles Midgard, biting its own tail; Jörmungandr releasing his tail is described as one of the signs of the beginning of Ragnarök. The name has been reused in modern astronomy for near-Earth asteroid 471926 Jormungandr (provisional 2013 KN6), discovered 28 May 2013.
