The Mongolian Death Worm has been reported as measuring anywhere from two feet long to four feet long. As worms often do, this monstrous legendary creature is also said to look like a snake, specifically a very thick and rather brilliant and vividly red snake. Such is the extent of the fear that the Mongolians express toward their Death Worm that merely mentioning its existence is considered bad luck. The method by which the Mongolian Death Worm exerts that luck is still up in the air, somewhat. Some people claim that the giant worm kills with a horrific poison that leaves victims gasping for their lives, while others claim that the Mongolian Death Worm kill in a much stranger fashion: through a powerful shock, almost like an electric eel.
Those who have investigated the legend of the Mongolian Death Worm have been told by nomads that the worm is highly attracted to the color yellow One of the most infamous stories of the Mongolian Death Worm is involves a young child who was playing with a yellow toy in which one of these words slithered. As soon as the boy went to pick up his toy, or so the story goes, death came instantly. The only sign of what had actually happened was a tail seeing disappearing into the sand by the child’s parents. The parents who went digging after the worm wound up just as dead as his parents.
As for the theories behind the reality of the Mongolian Death Worm, the basic premise seems to revolve around the idea that it is in reality merely a desert adder. The description of the Mongolian Death Worm matches that of the desert adder, a snake that fits roughly the same size, sprays poison, and could very well live in the environment of the Gobi Desert. The only problem is that this adder is only known for sure to exist in Australia and New Guinea. As for whether or not it is actually some kind of giant worm and not a snake at all, skeptics point out that the dry weather conditions that dominate the Gobi Desert would probably suck a worm into non-existence almost immediately. The most likely explanation for the Mongolian Death Worm, then, is that it is either a desert adder species that has yet to be discovered, or it is entirely an invention of desert nomads looking to explain away some mysterious deaths.
