Mongolian Death Worm

The Mongolian death worm (Mongolian: олгой-хорхой, olgoi-khorkhoi, "large intestine worm") is a creature reported to exist in the Gobi Desert. It is generally considered a cryptid: an animal whose sightings and reports are disputed or unconfirmed.

It is described as a bright red worm with a wide body that is 2 to 5 feet (0.6 to 1.5 m) long.

The worm is the subject of a number of claims by Mongolian locals - such as the ability of the worm to spew forth acid that, on contact, will turn anything it touches yellow and corroded (and which would kill a human), as well as its reported ability to kill at a distance by means of electric discharge.

Though natives of the Gobi have long told tales of the olgoi-khorkhoi, the creature first came to Western attention as a result of Professor Roy Chapman Andrews's 1926 book On the Trail of Ancient Man. The US paleontologist was not convinced by the tales of the monster that he heard at a gathering of Mongolian officials: "None of those present ever had seen the creature, but they all firmly believed in its existence and described it minutely."
