Said to live in the sands of the Gobi desert, tales of the Mongolian Death Worm have been told by Mongolians for as long as anyone can remember. Called olgoi-khorkhoi by locals, the death worm is reported to range in size from 2 to 5 feet long and have a wide red body, killing its prey with either a spray of sulfuric acid or electrical discharge. First described in western literature by Prof. Roy Chapman Andrews in 1926, no specimen has been found nor have any photographs of the creature emerged. Infact, several expeditions to the region have failed to uncover any evidence that the death worm exists outside of local folklore. However, access large portions of the Gobi along the Chinese/Mongolian border is prohibited. Unless researchers are allowed into the region, the mystery of the Mongolian Death Worm may never be laid to rest.
