Mongolian Death Worm?

Scientists search for Mongolian Death Worm Attempt to confirm existence of legendary beast.

Mongolian nomads have made extraordinary claims about the animal, reporting that the death worm can spit a corrosive yellow saliva that acts like acid and that they have the ability to generate blasts of electricity powerful enough to kill a full grown camel.

The Mongolian Death Worm is generally considered a cryptozoological creature, an animal whose existence is disputed and/or unconfirmed. To date there are no scientifically reliable sightings but the expedition's leader, cryptozologist Richard Freeman, hopes to prove once and for all whether this much feared beast of legend actually exists.

Freeman has his own theory on the death worm: I don't think that it's a worm at all. True worms need moisture. I think it is a limbless, burrowing reptile, probably a giant member of a group of reptiles known as amphisbaenas or worm lizards. These are a primitive group of poorly studied animals. They are not snakes or lizards but are related to both. I think the Death Worm is a giant member of this group. - mongabay
