#082 – THE MONGOLIAN DEATH WORM
🐉 From Doctor Who to the Gobi: A Cryptozoologist’s Origin Story
Richard credits his lifelong obsession with monsters to two things: Doctor Who and a genuine love of animals. Growing up in the 1970s, he was captivated by the era of the Third Doctor (Jon Pertwee), whose Earth-bound adventures featured monsters in familiar surroundings — giant maggots in Welsh slag heaps, intelligent marine dinosaurs, the Great Intelligence manifesting through London’s Underground. That sense of the monstrous hiding in the mundane world never left him.
He went on to become a zookeeper and eventually head of reptiles at Twycross Zoo in the Midlands — a background that later gave him a uniquely hands-on perspective on hominid cryptids. He discovered cryptozoology proper through a magazine called Animals and Men, the CFZ’s publication, and eventually moved to Devon to become the organization’s zoological director. The CFZ describes itself as the only full-time cryptozoological organization in the world.
🪱 What the Nomads Actually Say: The Death Worm Up Close
The Mongolian Death Worm — known locally as allghoi khorkhoi (“intestine worm”) — is frequently inflated by the time its legend reaches Western ears: blood-red, five feet long, spitting acid, discharging bolts of electricity. Richard’s CFZ expedition drove roughly a thousand miles through the Gobi interviewing nomadic witnesses, and the picture that emerged was far more grounded:
– About two feet long, roughly the thickness of a human arm.
– Sausage-shaped — difficult to distinguish head from tail — and scaly, reddish-brown in color.
– Believed by witnesses to be venomous and capable of spitting (turns things green, they say), but no one interviewed had actually witnessed the spitting or personally knew a victim — strictly friend-of-a-friend accounts.
– The “lightning” attribution? Witnesses themselves called it folklore.
– Typically seen near watercourses and oases; said to emerge after rain; sightings span May through September, despite a folk belief that it only appears in June and July.
The team interviewed roughly 24 witnesses, ranging from an elderly man who had seen one in the 1930s to a man in his 40s who had encountered one the previous year. One witness reported seeing a death worm eat a mouse; another saw one emerge from the roots of a saxaul tree. Crucially, one account described Russian scientists collecting snakes who killed a specimen and took it away — raising the tantalizing possibility that a preserved death worm may be sitting unlabeled in a former-Soviet natural history collection somewhere.
🔬 The Zoologist’s Best Guess: Amphisbaenian or Sand Boa?
Richard’s working hypothesis is that the death worm is not a worm at all — it’s a reptile. Two candidates emerge from the physical description:
– Amphisbaenians (worm lizards): neither worms, lizards, nor snakes, but a distinct group of burrowing, limbless squamates. Sausage-shaped, difficult to sex front from back — a match for nearly every feature witnesses describe.
– Sand boas: chunky, arid-adapted constricting snakes with a similarly cylindrical profile. Richard draws a direct parallel to the Somali abris — a sand boa that local people believe is so venomous that a mere touch is fatal, when in fact it is a harmless, mouse-eating constrictor.
The mythologization process, he argues, is consistent across cultures: a real but poorly-known animal acquires supernatural attributes through accumulated folklore — just as gorillas were once said to beat elephants with branches and carry off women. The exaggerated attributes don’t mean the animal doesn’t exist; they mean it hasn’t been studied. He cites Delcourt’s giant gecko — the world’s largest gecko, completely unknown to science — which sat on display in a Parisian museum for years before a gecko specialist happened past and recognized it for what it was.
🗺️ Field Methods: How You Hunt a Death Worm
The CFZ team’s practical approach in the Gobi combined witness testimony with active survey techniques:
– Targeting oases and watercourses, based on witness reports of the creature preferring moist microhabitats.
– Early-morning searches of desert terrain after rainfall — the conditions under which the animal is most often seen.
– Attempting to flood a small stream channel to force a burrowing animal to the surface (ultimately impractical due to the depth of the stream banks).
– Deploying pitfall bucket traps with drift fences — a standard herpetological survey method — between traps to intercept ground-level movement at night. Result: insects only.
Richard is sanguine about the outcome. The snow leopard, he notes, took zoologists six or seven years of dedicated fieldwork to film in the early 1970s; two weeks in a vast desert is barely a first acquaintance. He remains convinced that a patient, well-funded expedition — or a systematic search of Russian natural history museum basements — would crack the case.
🦎 Other Cryptids in the Field: Thylacine, Orang Pendek, Almasty
The conversation ranges well beyond the Gobi. Richard names the two cryptids he considers nearest to confirmed:
– The Thylacine (Thylacinus cynocephalus): officially extinct since 1936, but subject to more than 4,000 post-extinction sightings, including by zoologists and park rangers. Richard’s recent Tasmania expedition produced multiple credible witnesses — including a government-licensed shooter with no axe to grind — who insisted on anonymity to protect the animal. He notes that vast stretches of southwestern Tasmania are essentially roadless and uninhabited, reachable only by boat or helicopter.
– The Orang Pendek: Richard’s theory is that it represents a third extant species of orangutan — one adapted to terrestrial rather than arboreal life — distinct from both Pongo pygmaeus (Bornean) and Pongo abelii (Sumatran). Hair recovered during the CFZ’s 2009 Sumatra expedition was analyzed by Lars Thomas of the University of Copenhagen, who found the DNA similar to but distinct from Sumatran orangutan — though fragmented from environmental exposure. A French production company, Cienti, financed a more recent expedition, during which the team found tracks, handprints, and heard vocalizations.
He also recounts a particularly atmospheric night in the Caucasus Mountains in 2008 on the trail of the Almasty — a large bipedal creature sometimes theorized to be a relict population of early Homo erectus. At 2:30 a.m., Richard and colleague Adam Davies heard a deep guttural vocalization, followed by something bipedal walking along the veranda of an abandoned farmhouse, blocking out the moonlight to a height of seven feet. Whatever it was, it had vanished by the time they got outside.
📡 Roy Chapman Andrews, Tolkien, and the Western Mythology of the Death Worm
The death worm entered Western consciousness largely through Roy Chapman Andrews — the paleontologist and explorer widely considered a partial inspiration for Indiana Jones — who was warned about the creature by the Prime Minister of Mongolia during his 1920s expeditions. Andrews thought it nonsense but recorded it, and the account circulated from there. Richard also notes that an early draft of The Hobbit contains a reference to “killer worms from the deserts of the East,” thought by some Tolkien scholars to be a nod to the death worm legend. The creature’s range is southern Mongolia and the Gobi — a territory the size of Europe, with a population of roughly one million people and days of drivable terrain with no sign of human habitation.

THE MONGOLIAN DEATH WORM—its name conjures up images of fantastic beasts like the sand worms in Dune or the creatures from the film Tremors, but the actual legends are even stranger. We discuss the legends and facts behind this cryptid with the official zoologist for the Center for Fortean Zoology, Richard Freeman.
