Mongolian Death Worm reports in Roy Chapman Andrews’s writings

Record summary

Roy Chapman Andrews discussed Mongolian reports of the olgoi-khorkhoi, a feared wormlike desert animal said in local tradition to kill or disable people and livestock. The material entered English-language cryptozoological discussion through his Central Asiatic Expedition writings, although Andrews did not establish a zoological specimen or direct observation. This lead matters for comparing translated folklore, expedition-era collecting practices, and later sensational interpretations. The creature may reflect a culturally elaborated tradition, misidentified fauna, or a literary composite rather than an unknown species.
