THE GRUESOME GBAHALI - LURKING IN LIBERIA?

Since 1900, the West African country of Liberia, still plentifully supplied with coastal mangrove swamps and interior rainforests, and long deemed a biodiversity hotspot by zoologists, has been the scene of at least four major zoological discoveries of species new to science or rediscoveries of species believed extinct. Namely, the giant forest hog Hylochoerus meinertzhageni, the pygmy hippopotamus Choeropsis liberiensis, Jentink's duiker Cephalophus jentinki, and the Liberian mongoose Liberiictis kuhni.

All of these are mammals, of course, but there is also some thought-provoking evidence to suggest that a fifth major zoological find is still waiting to be made here – and this time of the reptilian variety.

Four species of crocodilian are known to exist in Liberia. These are the Nile crocodile Crocodylus niloticus, the West African dwarf crocodile Osteolaemus tetraspis, the West African slender-snouted crocodile Mecistops cataphractus, and the West African or sacred crocodile C. suchus (only quite recently delineated from the Nile crocodile as a valid distinct species in its own right). The first two are restricted to this country's coastal swamps, and are considered rare, as is the third (a little-studied, human-avoiding species), whereas the fourth one, which occurs further inland, is quite common.

However, native Liberians also speak of a fifth crocodile-like creature, currently unknown to science, which they refer to as the gbahali (pronounced 'bar-hye'), and consider to be larger and more dangerous than even the Nile crocodile – itself a highly aggressive, notorious man-eater that can grow up to 21 ft long.

The gbahali first attracted widespread Western attention on 20 December 2007, when veteran American cryptozoologist Loren Coleman published on the mystery beast website Cryptomundo a communication that he had received the previous day. It was from a correspondent named John-Mark Sheppard (some accounts spell his surname as Shephard) – an American missionary working at that time with an international relief and development organisation in northernmost Liberia's Lofa County, near this country's border with Guinea.

In his communication, Sheppard revealed that he had learnt from the indigenous people there about several strange, unidentified creatures that may be of potential cryptozoological interest, including the gbahali. He had spoken to a number of alleged eyewitnesses who claimed to have seen the latter mystery beast in recent years, and according to their testimony, as documented by Sheppard:

It is described as being like a crocodile or monitor lizard, but much larger (up to 25 or 30 ft long). It has an armored back with three rows of serrations running down it, a powerful tail, and a short snout with many large teeth. It is known to be an ambush predator, carrying its prey underwater to drown before coming on shore to eat it.

Sheppard even travelled to a village deep in the Liberian rainforest where the fishermen claimed to have actually caught gbahali specimens, using nets to capture them and shotguns to kill them, before butchering their carcases for meat, which they then sold at local markets. They had even preserved the skull of one such specimen, which had been retained in the village until rebels invaded it during this country's civil war (which ended in 2003) and set it ablaze, destroying everything there, including that scientifically-precious gbahali skull.

When interviewing the villagers, Sheppard showed them various illustrations of modern-day and prehistoric crocodilians and crocodilian-like animals that he had downloaded from the internet. Of these, the creature that they considered most similar in appearance to the gbahali was an artistic reconstruction of the likely appearance in life of a prehistoric reptile from North America's Late Triassic Period, known as Postosuchus. This very sizeable beast, up to 6 m long, belonged to a long-extinct taxonomic family whose members, known as rauisuchians, were related to crocodilians.

The locals stated that the head and body of Postosuchus as depicted in the artistic reconstruction resembled that of the gbahali, but that its legs were more erect (i.e. supporting its body from below) than the gbahali's, which are allegedly semi-erect in stance (i.e. more sprawling), like those of crocodilians.

Continuing his narrative, Sheppard stated:

The river in which these creatures are said to live is very remote, passing through large areas of uninhabited forest. They are said to mainly be seen during the rainy season, when they travel upstream to look for food. They are greatly feared by the local population, because they have been known to kill people.

Indeed, according to Sheppard one such incident may have occurred as recently as November 2007, just a month before he had sent his communication to Coleman. A man had been attacked and killed by a possible gbahali near a village named Gelema, on that selfsame river. When the United Nations police were sent there to investigate this incident, all that they could find was the victim's head and a few body parts that the creature had left behind on the river bank. This ties in with local claims mentioned above by Sheppard whereby the gbahali drowns its victim, then comes ashore with their dead body to consume it there.

Worthy of note, incidentally, is that back when Gelema's official town meeting house was built, its length was deliberately constructed so as to correspond with that of a gbahali that had been killed there some years previously. Consequently, this grim mystery beast would indeed appear to be native to the area encompassing Gelema.

Also of interest, as specifically pointed out by Sheppard when concluding his account of the gbahali, the local people do not consider this beast to be in any way magical or supernatural. Instead, they simply look upon it as just another normal, ordinary animal native to their locality (albeit a very large, dangerous one), nothing more – which in turn tends to lend plausibility to their testimony concerning it.

Sheppard ended with a tantalizingly brief mention of a photograph that had supposedly been taken of a gbahali sometime in the previous 10 years during an attempt to capture this creature, but he made no mention of what had happened to it, always assuming of course that such a picture had indeed been obtained.

After spending many years behind the camera as a first-rate, highly-acclaimed film/TV cameraman and cinematographer, in 2017 Paul 'Mungo' Mungeam stepped in front of it to present a new cryptozoology-themed TV documentary show entitled Expedition Mungo. Each of its episodes (filmed in 2016 and early 2017) saw him and his own film crew visit a different location around the world allegedly inhabited by a mysterious creature seemingly unknown to science. One of these episodes saw them in Liberia's Lofa County, seeking the gbahali, and where they actually interviewed Sheppard on screen.

Mungo's gbahali expedition focused its attention upon the Kahai River and its tributaries, where this greatly-feared creature is known by the locals to exist and where, therefore, they avoid as much as possible unless it is absolutely essential to cross from one riverbank to another or to hunt for food there. One villager named Momo informed Mungo that he and his brother had encountered a ghahali on land once while they were hunting on the Kahai River, but once seen it disappeared into the water.

Discounting the possibility that it was merely a crocodile, Momo stated that its head was lizard-like but with its eyes placed far back on it, a trait often exhibited by aquatic animals, and its teeth were interlocking. Moreover, although it walked on all fours like a crocodile, its body was raised up, held off the ground to a greater degree than a crocodile's is. He also mentioned to Mungo that one such creature had killed and devoured three men who had been attempting to cross the Kahai on a raft at dusk.

Similarly, another alleged gbahali eyewitness interviewed by Mungo, a man named Isaac from Monena, a remote Liberian frontier village, recalled an oft-told claimed killing of a man in a shallow river by a gbahali. The man had been attempting to cross the river on foot to reach a party of fisherman friends on the far bank. His friends told him not to cross, because a gbahali had been seen there earlier that same day, but he ignored their advice and proceeded to wade across. Before he could reach the other side, however, a gbahali surfaced, seized the man, and dragged him beneath the water, never to be seen again.

As for Isaac's own sighting, which had occurred not long before Mungo had arrived at Monena in early 2017: just like Momo, Isaac had been fishing with his own brother on the river nearby when he saw something swimming towards his brother:

He turned around and said: "It looks like a crocodile". I said: "Hey, that is not a crocodile, that is an animal bigger than a crocodile". We're talking about the Gbahali...The mouth was in the form of a lizard.

Isaac estimated the gbahali to have measured around 20 ft long, and insisted that it was very different in appearance from a crocodile.

Also interviewed by Mungo at Monena was fisherman Seiku, who divides his time between this village and a camp on an even more remote stretch of the Kahai. Seiku claimed to have seen a gbahali twice during his travails along this route in September 2016, again not long before Mungo's arrival here.

Several other villagers interviewed by Mungo at Monena also claimed to have seen a gbahali, but as Sheppard had discovered earlier during his own investigations, they did not consider it to be in any way magical or paranormal, just a normal, ordinary creature like all of the other animal species inhabiting this locality.

Sadly, Mungo and his team did not have any sightings of their own, but if, as fervently averred by Liberia's Lofa County hunters and fishermen, the gbahali is indeed a real, flesh-and-blood beast, what might it be?

The most conservative identity is the Nile crocodile (Liberia's other three crocodile species are much too small and/or wary of human proximity). Although officially confined to this country's coastal swamps, perhaps some stragglers have penetrated further inland, reaching rivers, tributaries, and surrounding terrain containing plenty of suitable prey, enabling them to thrive and establish viable populations there, and possibly eventually attaining greater sizes than their coastal ancestors, their increased weight readily buoyed by their watery habitat.

Yet the locals are adamant that the gbahali is no ordinary crocodile, or even a crocodile at all, emphasizing its short-snouted, lizard-like head and its more erect limbs as notable differentiating features. Also, its claimed behaviour of killing its prey in the water by drowning it but then bringing it onto land to consume it differs from typical crocodile feeding behaviour, in which the prey is normally eaten in the water, the latter being utilized as a means of softening the prey's carcase for easier consumption.

An alternative crocodilian option to consider is an unknown giant-sized species or morphological variety of West Africa's Osteolaemus dwarf crocodile. This is certainly appealing, inasmuch as it would combine the latter's shorter muzzle and more terrestrial lifestyle as reported also for the gbahali with the gbahali's extra-large size. 

Looking beyond crocodiles, Liberia is home to some sizeable monitor lizards (varanids), including the West African Nile monitor Varanus stellatus, up to 7.2 ft long, whose heads, more erect stance than crocodiles, and terrestrial consumption of prey recall the gbahali. However, the latter's great size (even allowing for exaggeration upon the part of its frightened eyewitnesses) and its very distinctive armoured, tri-serrated dorsal surface do not.

Now for the Postosuchus possibility. On the one hand, as noted earlier here, in terms of both shape and size a reconstruction illustration of this creature was compared quite favourably with the gbahali's alleged appearance by the villagers to whom Sheppard showed it. Also, its fossils have been found in locations believed to have hosted back in the time of Postosuchus an environment similar to the present-day habitat in Liberia where the gbahali reputedly exists, i.e. tropical, moist, and plant-plentiful, well-supplied with rivers and other expanses of freshwater.

Conversely, Postosuchus belongs to a long-extinct, wholly prehistoric family of reptiles known only from what is now North America, and existing during the late Triassic Period, i.e. approximately 201-237 million years ago – none of which bodes well for it being a plausible identity for the gbahali.

True, we cannot entirely rule out the prospect that the latter constitutes a modern-day Old World descendant of Postosuchus that has somehow entirely evaded scientific detection (like its presumed fossil antecedents here), especially in such a heavily-forested remote region as northern Liberia. Nevertheless, the further back in time that the original creature existed, and the further away geographically-speaking that it existed from where its postulated descendant does today, the less likely such an example of prehistoric survival is, by definition.

In addition, based upon its shorter forelegs, Postosuchus is nowadays commonly deemed to have been at least partly, if not exclusively, bipedal, whereas the gbahali is wholly quadrupedal. Also, Postosuchus is believed to have been terrestrial, rather than aquatic or at least amphibious in lifestyle as the gbahali is stated to be.

Another putative prehistoric survivor that has been considered as a possible gbahali candidate is some form of modern-day descendant of Kaprosuchus saharicus. This was a 20-ft-long semi-aquatic species of mahajangasuchid crocodyliform that sported an armoured snout for slamming its prey down, plus three pairs of sizeable tusks for tearing the latter's flesh. These teeth have earned for it the nickname 'BoarCroc', due to their superficial resemblance to the tusks of wild boars.

Unlike Postosuchus, K. saharicus, as its name indicates, did live in Africa (its fossilized remains have been excavated in what is today Niger), but approximately 95 million years ago, during the Late Cretaceous. Consequently, it is beset by much the same chronological issues as Postosuchus when under consideration as a plausible example of prehistoric survival.

If only there could be a known, historically-recent creature resembling and behaving rather like the gbahali. In fact, there is – or was. The mekosuchines constitute a taxonomic clade of crocodilians that included certain representatives which persisted into the present-day geological epoch, the Holocene (beginning less than 12,000 years ago), on various Pacific island groups, including Fiji, Vanuatu, and New Caledonia.

Indeed, one genus, Mekosuchus, survived on those islands until at least as recently as 3,000 years ago, possibly even longer (as late as 1720 BP, i.e. 300 AD, in the case of the youngest species, M. inexpectatus), before apparently being exterminated when humans arrived there (although, tellingly, there is no direct evidence for this, only speculation based upon the fates of other island endemics once our own species reached their insular domains). Various other, older mekosuchine genera, such as Quinkana, as well as earlier Mekosuchus representatives, formerly existed on mainland Australia.

M. inexpectatus in particular was notable for its short snout, and like its other historically-recent Mekosuchus kin is thought to have adopted a much more upright stance and mode of walking than any of today's known crocodilians, all of which draws comparisons with the gbahali. So too does the consensus that M. inexpectatus probably inhabited tropical rivers and streams, just like West Africa's present-day dwarf crocodiles, possibly coming onto land at night to feed.

In stark contrast to the gbahali, however, mekosuchines were of only very modest dimensions, generally no more than 6 ft in total length, sometimes even shorter than that. Also, just as Postosuchus is known only from the New World, mekosuchines are known only from Oceania; there is none on record from Africa, or anywhere else in the world.

Even so, the mekosuchines are relevant to the gbahali saga inasmuch as their existence, albeit far-removed geographically from the latter cryptid, confirms that at least some crocodilians of comparable appearance to it (excluding total length) are indeed known from modern times, thus providing a notable precedent – and that may not be all.

Convergent evolution is a familiar phenomenon whereby animals in widely disparate geographical localities and often of only distant taxonomic affinity nevertheless transform through time into outwardly similar creatures due to sharing the same ecological habitat and niche. So could it be that ecologically-speaking, the taxonomically-distant gbahali has nonetheless evolved a mekosuchine morphology by existing in a habitat comparable to that of the latter crocodilians, but has attained a much greater size due to its habitat's remote location coupled with the fear that it generates among human hunters, who generally prefer to avoid it rather than confront it? As suggested earlier here, a giant-sized Osteolaemus comes to mind.

In short (unlike the gbahali itself, which is allegedly anything but short!), could Liberia's mystery reptile be a totally novel, as well as a currently undescribed, species of African crocodilian?

Alternatively, turning full circle through the succession of identities considered here, might this cryptid simply be an unusually large form of Nile crocodiles after all? The reason that I've returned to this option is that I am well aware that there is a common tendency among local non-scientific people who intimately share their lives alongside large, potentially dangerous creatures to give a completely separate name to exceptionally large specimens of such a species from the name that they give to normal-sized specimens of that same species, treating the outliers as a fundamentally different animal type from their typically-sized brethren.

So might it simply be that reports of gbahalis are nothing more than reports of exceptionally large Nile crocodiles that have been given this separate local name?

The problem with such a proposed resolution to the gbahali mystery, however, is that we can only accept this by conveniently ignoring the other morphological, and behavioural, differences from normal Nile crocodiles that the locals ascribe to the gbahali – which in my opinion would be very unwise.

History has shown time and again how, by taking heed of local, native testimony, extraordinary animals hitherto dismissed by Western zoologists as mere folklore have been formally discovered and revealed to be remarkable species entirely new to science.

So, might the gbahali one day prove to be another one? In view of the giant forest hog, pygmy hippo, Jentink's duiker, and the Liberian mongoose, I'd have to think more than twice before betting against such a prospect.

THE BIS-COBRA – INDIA'S VENOMOUS LIZARD THAT NEVER WAS


First edition of EHA's delightful book, The Tribes On My Frontier (public domain)


Snakes of all kinds are held in great horror by the natives of India, and they slay indiscriminately and ruthlessly all they come across, but this horror pales before the terror inspired even by the names of the bis-cobra and goh-sámp,—terror so great, that, if met with, the harmless animals are given the widest berth possible, and their destruction is never attempted. Though actual animals, they are virtually mythical, that is as regards the deadly properties assigned to them, and we easily recognise in them the originals of the flame-breathing dragon and deadly basilisk. The gaze of the bis-cobra is awful even from a distance and its bite is instant death; and if the goh-sámp breathes upon, or at you, you fall dead at once.

   H.F. Hutchinson – Nature, 9 October 1879


In villages across the length and breadth of India even today, there remains tangible fear concerning a creature that may be small in size but is gargantuan in terms of the terror that the mere sight of it generates. Known most commonly as the bis-cobra, according to generations of fervently-believed native folklore and superstition this modest-sized Asian lizard has such a venomous bite that anyone so inflicted will die instantly. Needless to say, no species matching this description is known to science. Yet there is no doubt that the bis-cobra does exist. So what precisely is this noxious entity, and how can these contradictions be resolved?

The name 'bis-cobra' (or 'biscopra'), which is used most prevalently in western India, loosely translates as 'venomous cobra'. Bearing in mind that all cobras are venomous, this is a particularly direct, hard-hitting way of emphasising just how exceptionally toxic this animal is – or, to be more accurate, allegedly is.

I first read about the bis-cobra many years ago, when perusing a delightful, humorous book on Indian wildlife entitled The Tribes On My Frontier, published in 1904 and written by 'EHA' - the pen-name of Indian amateur naturalist and artist Edward Hamilton Aitken (1851-1909). His description of it summarises very succinctly the basic attributes of this mysterious reptile:

But of all the things in this earth that bite or sting, the palm belongs to the biscobra, a creature whose very name seems to indicate that it is twice as bad as the cobra. Though known by the terror of its name to natives and Europeans alike, it has never been described in the proceedings of any learned society, nor has it yet received a scientific name. In fact, it occupies much the same place in science as the sea-serpent, and accurate information regarding it is still a desideratum. The awful deadliness of its bite admits of no question, being supported by countless authentic instances; our own old ghorawalla [horse-keeper] was killed by one. The points on which evidence is required are – first, whether there is any such animal as the biscobra; second, whether, if it does exist, it is a snake with legs or a lizard without them. By inquiry among natives I have learned a few remarkable facts about it, as, for instance, that it has eight legs, and is a hybrid between a cobra and that gigantic lizard commonly miscalled an iguana [in India, 'iguana' is a term popularly misapplied to monitor lizards]; but last year a brood of them suddenly appeared in Dustypore, and I saw several. The first was killed by some of the bravest of my own men with stones, for it can spring four feet, and no one may approach it without hazard of life. Even when dead it is exceedingly dangerous, but, with my usual hardihood, I examined it. It was nine inches long, and in appearance like a pretty brownish lizard spotted with yellow. It has no trace of poison-fangs, but I was assured that an animal so deadly could dispense with these. If it simply spits at a man his fate is sealed.

After some effort, EHA finally managed to capture a bis-cobra alive in his own garden using a butterfly-net, much to the great consternation of his native butler, watching the proceedings from a considerable distance. He then kept it for a time as a pet, without suffering any adverse effects.

EHA's own bis-cobra drawing in The Tribes On My Frontier (public domain)

Pre-dating EHA's account by several decades, however, was a lengthy report on the bis-cobra by a Mr John Grant that featured in the inaugural volume of the Calcutta Journal of Natural History, published in 1840. In it, Grant referred to a specimen of a reputed bis-cobra specially captured for him to examine. Approximately 6 in long, it was attractively patterned with irregular streaks of small bead-like markings of alternating dark and light grey colour. Anxious to observe its lethal effect, Grant introduced a mouse into the glass container housing this lizard. But far from the mouse meeting a rapid demise, it fought spiritedly with the lizard for a short time, each biting the other, before the two combatants retreated to opposite sides of the container, neither of them appearing any worse for their savage encounter. So much for the bis-cobra's virulent venom.

In her book East of Suez (1901), Alice Perrin included an eventful incident in which a European living in India demonstrated dramatically but beyond any doubt that the bite of a bis-cobra was harmless. He achieved this by lifting a brown and yellow specimen out of a pot in which it had been trapped, and then, when it seized hold of his hand with its teeth, holding it up, still biting him, for all of his horror-stricken native helpers to witness. After anxiously waiting for a while to watch their doomed master's fully-anticipated demise, they finally dispersed when it became clear that he was totally unharmed. Perrin also documented an encounter with a tree-climbing bis-cobra, measuring about 14 in long.

EHA was not the only source of native lore claiming that the bis-cobra doesn't even have to bite in order for its venom to prove lethal. Several other writers have also alleged that it only has to spit a single drop onto someone's skin for its potency to prove instantaneously fatal, searing through the victim's skin, entering their bloodstream, and eliciting certain death. Indeed, in his book Indian Peepshow (1937), Henry Newman was even assured by a local man that if this dire lizard so much as spat at a tree (let alone a person), a hole would burn right through and the tree would die.

In parts of India outside the western zone where reports of the bis-cobra are most rife, this supposedly deadly beast is conflated with another mysterious but equally malign reptile called the hun khun. Likened to a small slow-moving lizard with a fat tail, much the same powers of venomous potency are attributed to it as to the bis-cobra, but even the blood of the hun khun is reportedly toxic, and its skin reputedly contains lethal poison glands.

As science knows of no species corresponding to the bis-cobra, how can this enigmatic lizard be explained? Down through the decades, several different zoological identities have been proposed for it. In their book Venomous Reptiles (1969), Sherman and Madge Minton proposed that the bis-cobra was the East Indian leopard gecko Eublepharis hardwickii, a small stout species with a noticeably thick tail. Of course, as this gecko (like all others) is wholly harmless, in order to accommodate its identification as the bis-cobra the latter's dread reputation as a highly venomous creature must necessarily be nothing more than native superstition and folklore. The Mintons identified the hun khun as the closely related fat-tailed or common leopard gecko E. macularius.

Henry Newman noted that in the hotter, drier parts of India, 'bis-cobra' was a term applied to a rarely-seen, fleet-footed species of grey lizard. And that in Eastern Bengal, it is an elusive crested lizard occasionally spied in gardens and on walls.

In his recently-updated two-volume encyclopaedia of cryptozoology, Mysterious Creatures (2013-14), George Eberhart noted the Mintons' view. He also speculated that an alternative explanation for the bis-cobra is that it is a non-existent composite beast, created by locals combining (and sometimes confusing) reports of venomous snakes with non-venomous lizards.

By far the most commonly-held view as to the bis-cobra's identity today, however, is one that, ironically, had originally been suggested by a number of authors more than a century ago. In his earlier-mentioned book, for instance, EHA recalled how his captured bis-cobra gradually grew larger until within a few weeks it had developed into an unmistakeable 'iguana' (in India, a commonly-used colloquial, albeit zoologically-inaccurate, name for a varanid or monitor lizard). He concluded dryly:

Some people would jump to the conclusion that it was a young iguana to begin with. My butler would endure the thumbscrew sooner.

Similarly, in his above-documented Calcutta Journal of Natural History report from 1840, John Grant concluded that the specimen which he had pitted against the mouse was nothing more than a young goshamp – a local name in present-day Bangladesh and West Bengal for the common Indian (Bengal) monitor Varanus bengalensis. This species is widely distributed throughout the Indian subcontinent, and whereas adults are mainly terrestrial, juveniles are more arboreal, thereby explaining reports of tree-climbing bis-cobras. Their spotted patterning also matches morphological descriptions of the bis-cobra.

Moreover, writing in Beast and Man in India (1891), John Lockwood Kipling stated:

The large lizard, varanus [sic] dracaena, which is perfectly innocuous, like all Indian lizards, is called the bis-cobra by some.

Varanus dracaena is a synonym of Varanus bengalensis. Kipling actually owned a pet specimen of this monitor species, and whenever he held it he was invariably warned of its supposed deadliness by native observers.

Monitors were also confidently identified as the bis-cobra by L.S.S. O'Malley in his book Bengal, Bihar, Orissa and Sikkim (1917). In Eye in the Jungle (2006), acclaimed Tamil writer M. Krishnan affirmed that the dreaded bis-cobra has been shown by naturalists to be nothing more than young, harmless specimens of the common Indian monitor – a statement confirmed in the standard work on this varanid species, Walter Auffenberg's monograph The Bengal Monitor (1994). Today, therefore, the term 'bis-cobra' is treated merely as a synonym for the latter monitor.

All that remains to explain now are supposed cases (such as that of EHA's ghorawalla) in which a bite from a bis-cobra, i.e. a young Indian monitor lizard, caused a person's death. If such cases are indeed genuine, how are such deaths possible, bearing in mind that V. bengalensis is not venomous?

Various possibilities come to mind. For instance, in recent years it has been shown that certain varanids, notably the Komodo dragon V. komodoensis, do actually possess venom glands. Although the venom produced by them is not normally fatal to humans, someone exceptionally sensitive to it may conceivably suffer anaphylaxis in a manner comparable to the response of certain people to the venom in bee or wasp stings. And even if no venom is present, the bacteria present on the teeth of these lizards could readily infect a wound created by a bite from one, and thus induce septicaemia. Moreover, the superstitious fear generated by the bis-cobra may in itself be sufficient to bring about death by heart failure in someone bitten by a monitor lizard.

It may well be that isolated incidents involving one or more of these causes of death following a bite from a technically harmless lizard were sufficient to engender the tenacious myth of the lethal bis-cobra, especially among medically-untrained villagers. It would also explain the diversity of lizard species claimed by them to be the bis-cobra at one time or another. The ultimate result was a fascinatingly Frankensteinian creation of the deadliest lizard that never actually existed.

THE IRAQI AFA - A MIDDLE EASTERN MYSTERY LIZARD



Salvator water monitors - could the afa be an unknown giant relative?

One of the world's most obscure cryptozoological reptiles is the afa - a Middle Eastern mystery lizard briefly reported by explorer Sir Wilfred Thesiger in his book The Marsh Arabs (1964).

Also known as the Madan, the Marsh Arabs inhabited the marshlands of the Tigris and Euphrates rivers in the south and east of Iraq, and along the Iranian border – formerly a vast area of wetland covering more than 5.8 square miles. According to Thesiger, who had lived among them intermittently for eight years during the 1950s prior to the Iraqi revolution of 1958, the canoe-borne Madan claimed that the marshes at the mouth of the Tigris in Iraq was home to a monstrous lizard, which they termed the afa.

Little else appears to have been documented concerning it. As various species of varanid or monitor lizard are native to this region of Asia Minor, however, it is plausible that the afa may be one too, albeit bigger than those formally recognised by science here - and hence either an unknown giant species, or based upon sightings of extra-large specimens of some known species.

Sadly, however, the question of the afa's taxonomic identity may be nothing more than academic nowadays. This is because following the Gulf War in 1991, the Iraqi government initiated a major programme to divert the flow of the Tigris and Euphrates Rivers away from the marshes in retaliation for a failed Shia uprising among the Arabs living there. This not only eliminated the Madan's food sources, forcing them to move elsewhere, but also turned the marshes themselves into a desert.

Consequently, the afa may well have been exterminated, especially if it were primarily aquatic, as I am not aware of any post-1991 reports alluding to it. If any ShukerNature reader is aware of any such reports, however, I'd be very interested to receive details.
