The fabled Mongolian Death Worm is something to be feared, if it's real.
Cryptozooligists the world over are fasinanated by the allerghoi horhai (roughly translates to "intestine worm") or Mongolian death worm.
It first became known to the west in the 1920s and its alleged powers are impressive.
Although small, about half a metre long and about 10 centimeters thick, it can spray poison from a distance as well as kill with something like an electrical charge.
Supposedly inhabiting the southern Gobi desert, there has never been any real evidence of its existence, although a few expeditions have attempted to uncover a specimen.
Brian Dunning has investigated the history and claims surrounding this cryptid and has found the legends and folk tales about the Mongolian death worm are the best and most valuable part of its legacy.
