Something has crept, or has been driven out of dark waters under the mountains...Far, far below the deepest delvings of the Dwarves, the world is gnawed by nameless things.

   J.R.R. Tolkien - The Lord of the Rings

Could the Bodalog Beast have been a large snake species living in Britain and readily able to swim, such as the grass snake, as depicted here in a beautiful illustration by Heinrich Harder from 1912? (public domain)

Thirty years ago, one of the strangest, eeriest cryptozoological cases ever reported from the British Isles was making headlines nationally and even internationally, and three decades later it has still never been satisfactorily resolved. So here is my contribution to its very intriguing history, by way of an article of mine that was subsequently converted into a chapter within my book From Flying Toads To Snakes With Wings (1997) and serves now in updated form as a fitting ShukerNature retrospective to, and reminder of, this macabre yet nowadays all-but-forgotten saga.

To describe one of Britain's most bizarre mystery beasts as a water vampire may not be as melodramatic as one would first suppose - especially after considering its unique characteristics. According to media reports, during September to December 1988 its home was seemingly a lengthy river, the River Wye, situated close to the town of Rhayader in mid-Wales, from which it apparently emerged at night to kill sheep on a nearby 2000-acre farm called Bodalog, owned by the Pugh family. Unlike those of foxes and dogs, however, its victims' carcasses were not ripped or torn in any way. Instead, the only sign of their mystifying marauder's attack was a small but deep, penetrating bite just below the neck, close to the sternum or breast-bone (and which duly earned it the memorable monicker of water vampire in some media accounts). No evidence of the creature feeding upon the carcasses was found either, thus making its predatory behaviour even more weird and difficult to understand.

Nevertheless, by the middle of October 1988 this mysterious beast had killed at least 35 sheep. Its scent had been trailed back and forth to the river by foxhounds, but it was never seen or identified, and no recognisable pawprints were found either. As noted by London's Daily Mail newspaper on 10 October 1988, many suggestions regarding its possible identity had been offered, ranging from otter and dog, to mink and even to some form of snake. University scientists had examined the carcasses and admitted to being thoroughly perplexed.

Their bewilderment is not surprising, as the Bodalog beast clearly poses some singular problems, with none of the more conservative explanations satisfying the facts available.

Could it have been a native European otter (above) or a naturalised American mink (below) (public domain / © Cephas/Wikipedia CC BY-SA 3.0 licence)

Its aquatic habitat immediately rules out a fox, cat (even an escapee big cat), or stray dog as the culprit - as well as a human hunter using a crossbow, which had also been suggested by some authorities. European otters Lutra lutra are relatively large creatures, but are certainly not sheep killers. They are known to take small mammals in their diet from time to time, but nothing approaching the size of a sheep. In any event, their principal sources of food are fishes and aquatic crustaceans - and, needless to say, they do eat prey killed by them and they do leave tell-tale spoor behind.

Mink, although much smaller than otters, are far more bloodthirsty by nature. Not native to the British Isles, they now exist in a naturalised state in many parts of the country - descendants of fur-farm escapees belonging to the American species, Neovison vison. Mink have wide tastes, ranging from fishes to birds as large as moorhens, and mammals as large as young rabbits (reports even exist of mink having killed pet cats and dogs!). Nevertheless, sheep would surely be far too large for any mink to tackle successfully.

One suggestion, from an unnamed 'expert', was that some form of giant mink was responsible! Mink, however, do not normally attain a total length greater than about 26 inches in the wild, and there is no evidence whatsoever that mink of a size commensurate for sheep killing have ever existed in Britain.

A little-known species called the sea mink N. macrodon once inhabited the coastal waters of New England and the Canadian maritime provinces, and was indeed somewhat larger than other mink species, but it became extinct in the early 1880s, and is totally unknown either in living or in fossil form in the Old World.

Britain only has three native species of snake. [NB - herpetological researchers revealed in 2017 that there were actually two taxonomically distinct species of grass snake living here, not just one, but only one of them is native, namely Natrix helvetica; unfortunately, various media reports confusingly and erroneously claimed at the time that both of them were native and that there were therefore four native snake species existing here.] The sole venomous species is the European viper or adder Vipera berus, which is predominantly ground-living, diurnal, and feeds on nothing larger than lizards and small mammals.

Relatively more aquatic by nature are the non-venomous and diurnal eastern grass snake Natrix natrix (represented in Britain via various small, introduced, non-native populations) and its close relative the western or barred grass snake N. helvetica, the new name for Britain's native grass snake species. The preferred prey species of these two species are amphibians and fishes, though nestling birds and small mammals are also occasionally taken.

In addition, Britain has a small number of the smooth snake Coronella austriaca, again native but confined to southern England. This is another non-venomous, diurnal species whose diet consists mainly of lizards and small mammals.

Also worthy of note is the aesculapian snake Zamenis longissimus, which is a mainland European species that has established a couple of small but seemingly thriving naturalised population in Great Britain – one in central London, England, and the other in Colwyn Bay, Wales. Both populations originally arose from escapee/released specimens surviving and mating in the wild in these locations. So might the Beast of Bodalog have been an aesculapian snake, derived from the Welsh contingent? At up to 7 ft long, this species is certainly lengthier than any of Britain's native species, but just like all of them it is diurnal, and it is not venomous. Clearly, therefore, none of these five species constitutes a very convincing candidate for the Welsh sheep killer.

It has never been formally ascertained whether the Pughs' sheep were actually poisoned by their attacker, but if tests were to reveal that this did occur, then it is possible that a non-native and evidently sizeable, aquatic venomous snake was on the loose at that time. It could have been a pet that either escaped or, for some reason, was released, as in the above-noted London and Welsh instances featuring the aesculapian snake. Yet if this were true, then it could have potentially posed a very real, severe dilemma - for there are few animals on Earth as elusive as snakes, especially those species that are adept at travelling not only across the land but also through the water.

Perhaps, then, it is not too surprising that the sinister 'water vampire' of Wales was never seen, let alone tracked down. Its killing spree abruptly ended in early December 1988, and nothing like it has ever been reported since from Bodalog (or anywhere else, for that matter, at least as far as I am aware), so presumably it simply died (see below) - always assuming, of course, that it didn't move elsewhere. Yet if it had indeed been some form of very large, powerful snake, why did it kill so many sheep but never make any attempt to feed upon their carcasses afterwards?

Moreover, how could such a creature have survived for at least two months in the distinctly chilly climate present in mid-Wales during late autumn/early winter? After all, snakes are poikilothermic (cold-blooded) and therefore rely upon warm external, environmental temperatures to maintain their own body heat. Like all others associated with this decidedly strange saga, these questions are likely to remain unanswered indefinitely.

Front cover of Lofty Abodes by Philippa Foster (Text and cover artwork © Philippa Foster)

Over the years, I have been very fortunate and privileged that a number of my cryptozoological articles and books have contained exquisite illustrations by the extremely talented artist Philippa Foster. One of her most beautiful and, indeed, spectacular artworks, featuring a pair of ethereal sky medusae, even featured on the front cover of one of my books, Dr Shuker's Casebook (2008).

Knowing of and sharing Philippa's abiding love of the countryside and all of nature's endearing, enduring works, as well as her interest in magical realms, I have wondered on more than one occasion whether one day she may venture beyond the art world and into the written word too during her depictions of these mutually fascinating subjects, and I'm delighted to say that recently she did indeed do so.

The result is an absolutely charming story for children entitled Lofty Abodes, written and published by Philippa, which I read a while ago and thoroughly enjoyed.

Set in the Brecon Beacons of Wales, and unfurling under the watchful eyes of the Red Sandstone Guardians, it weaves a magical, enchanted tale featuring both the familiar and also various cryptozoological creatures that make their home in this famously spectacular realm in Great Britain, from lonely trolls and friendly red kites to a glow worm city, rollicking rabbits, and a tantalising assortment of teasing puzzles and riddles too.

Back cover of Lofty Abodes by Philippa Foster (Text and cover artwork © Philippa Foster)

Significantly, it also includes something that Philippa (and I) consider very important (but sadly all too rare nowadays) in books for youngsters – a happy ending. Why do children's authors seem obliged lately to include some gritty, heartless denouement to their stories? The real world is gritty and heartless enough – surely the whole point of fiction, especially children's fiction, is escapism, to flee from the hardships of existence if only for a little while by seeking the warm, comforting, uplifting solace of a story in which the world is a finer, happier place, where worries can be forgotten and dreams of a better land and life can be born, nurtured, and, who knows, possibly even retained and given substance to when their dreamers have returned to grim reality.

With Christmas rapidly approaching, it gives me great pleasure to introduce Lofty Abodes here on ShukerNature, as I am certain that it would make a delightful and much-treasured gift for children, and not just young ones but children of all ages, for anyone, in fact, who carries in their heart the joy and unadulterated love of nature and wild things that they first experienced as children. Copies can be purchased directly from Philippa via her website, and also here on Amazon's UK website when available there.

Magnificent painting portraying William Beebe's striped manta ray (© William M. Rebsamen)

In 1999, my book Mysteries of Planet Earth became the first cryptozoologically-oriented book to include a specific section on what must surely be one of the most strikingly beautiful mystery beasts ever reported, and its coverage was greatly enhanced by the inclusion of a spectacular full-colour painting of this animal - another first for it - prepared specially for my book by renowned cryptozoological artist William M. Rebsamen (and which also opens this present ShukerNature blog article). Neither of us realised at that time, however, that only a few years later I would actually witness just such an animal, and in a wholly unexpected manner. The following article – the most detailed that I have ever prepared on this particular subject and constituting a ShukerNature exclusive – contains not only all of the information that I included in my 1999 book but also various additional cases uncovered by me since then, including my own afore-mentioned observation. So where better to begin it than with that observation – and here it is.

On 20 July 2005, I was sitting in front of the television at home in the UK, flicking idly between channels, when I happened to click onto Channel 5, and within a few seconds beheld an extraordinary sight. The programme being screened was a documentary entitled 'Whale Shark: Journey of the Biggest Fish in the World'. However, the fish that I was staring at in amazement was anything but a whale shark. It was a giant manta ray Manta birostris - a huge, superficially nightmarish beast popularly dubbed a devil-fish (see also here) due to its mouth's pair of demonic, horn-resembling, laterally-sited cephalic fins, and its huge batwing-like pectoral fins, uniformly dark on top, white below...except that this particular manta's pectorals were most definitely not uniformly dark on top. Instead, they were dramatically adorned by a longitudinal series of white v-shaped chevrons, and also sported pure white wing tips. This spectacular vision soared gracefully through its underwater domain for a few moments before the camera moved on to other subaqueous delights, and it did not appear again.

Not having tuned in to this programme from the beginning, I had no idea where the striped manta had been filmed, but the very next section of the documentary stated that the whale shark star of the show had now reached the Mozambique Channel, apparently having travelled there from the Seychelles region of the Indian Ocean. So this may have been where the manta footage had been shot.

What made this serendipitous sighting so notable was that for a great many years (right up to the time when I viewed the above-cited TV programme, in fact), mainstream zoology had tended not to recognise the existence of mantas other than the mundanely standard dark-dorsal, pale-ventral version. Yet there on screen was positive proof that at least one manta of a decidedly more flamboyant variety was indeed real. Nor was it unique. Several other specimens have been documented down through the decades, exhibiting a range of patterns, and spied in many different oceanic localities.

The earliest one that I have on record, and which remains the most famous (it was the subject of William Rebsamen's magnificent painting), was witnessed on 27 April 1923 by American naturalist William Beebe and several others while aboard his expedition vessel Noma, as it approached Tower Island in the Pacific Ocean's Galapagos archipelago. The manta ray briefly struck the side of the vessel and then sped swiftly away along the surface, providing its observers with an excellent view. According to Beebe, who later sketched it:

From tip to tip of wings it was at least ten feet, of somewhat the usual manta or devil-fish shape, except that the wings were not noticeably concave behind, and the lateral angles were not acute. The cephalic horn-like structures were conspicuous and more straight than incurved. In general the back was dark brown, faintly mottled, while the most conspicuous character was a pair of broad, pure white bands extending halfway down the back from each side of the head. The wing tips also shaded abruptly into pure white.

Documenting this dorsally-bicoloured manta in his book Galapagos: World's End (1924), Beebe considered that it may represent an unknown species.

Beebe's sketch of the striped manta ray observed by him off the Galapagos archipelago's Tower Island in 1923 (public domain)

In Vol. 12 of the now-defunct International Society of Cryptozoology's scientific journal Cryptozoology (covering the period 1993-1996), German researcher Gunter G. Sehm's paper on striped manta rays surveyed some other specimens. In 1924, fr example, a small manta was harpooned off the shore reef at Kiribati's Fanning Island (renamed Tabuaeran). Its dorsal surface was blue-black but also bore two large ash-coloured v-shaped chevrons that spanned the entire dorsum from left pectoral edge to right. In 1934 this specimen was deemed a new species and dubbed Manta fowleri, but its separate taxonomic status is no longer recognised.

In 1975, British Museum ichthyologist Alwyne Wheeler's book Fishes of the World contained a colour photograph of a manta ray that appeared to have some white striping on its right shoulder, although few details can be discerned because the picture had been taken side-on. A year later, a book by Pierre Fourmanoir and Pierre Laboute detailing the fishes native to the waters around New Caledonia and the New Hebrides included a colour photo of a manta ornately adorned with dorsal white banding and cephalic fins. In his paper, Sehm also included three hitherto-unpublished stills from a 30-second footage of film showing a manta with a pair of striking, laterally-sited, v-shaped dorsal markings, filmed off the coast of Mexico's Baja California by Sigurd Tesche, which had been broadcast by German TV on 28 December 1989 within a programme entitled 'Sharks: Hunters of the Seas'.

Correspondent Alan Pringle contacted me shortly after watching, on 7 November 1999, a BBC1 television programme 'Holiday Guide to Australia', to inform me that it had contained a snippet of film depicting a manta with two converging longitudinal dorsal white bands, filmed from above by a helicopter, as it swam above a reef in Australia's Great Barrier Reef.

I learnt from fellow crypto-enthusiast Matt Bille that on 19 September 2003, yet another striped manta made an unexpected television appearance, this time in the American reality game show 'Survivor', when a manta ray sporting a very prominent pair of white shoulder markings, resembling filled-in triangles along the body, cruised fleetingly just under the clear waters off Panama's Pacific coast.

Not long after my own television sighting in July 2005, I was informed of two separate webpages each containing a colour photograph of a striped manta. One of these, which still appears here, shows a manta with symmetrical lateral chevrons resembling those of the Baja California individual, but it also has white rings around its cephalic fins, a pale patch at the dorsal tip of its left pectoral fin (its right cannot be seen dorsally), and what looks like a white dorsal tail surface. More photos of it have since appeared on Wikipedia and elsewhere online, confirming that it does have a white patch at the dorsal tip of its right pectoral fin too. It was photographed at Hin Daeng, off Thailand.

The other page (no longer directly online at http://www.accessnoaa.noaa.gov/images/monitor1.jpg but still accessible here - thanks to the Wayback Machine Internet Archive) – in a website run by America's National Oceanic and Atmospheric Administration (NOAA) - showed an ornately-marked specimen with very extensive white wing tips linked posteriorly by a pair of white converging arcs, as well as white cephalic fins. No details of where this photo was taken were given.

In short, a diverse spectrum of striped mantas is on record, with no two alike, but collectively confirming that dorsally bicoloured individuals do indeed exist. So how can they be explained? Interestingly, some of them, notably Beebe's specimen, the Fanning Island manta, and the Baja California example, have conspicuously shorter-than-typical tails, and also the shape of their pectorals do not exhibit such marked convexity of the front edge and concavity of the trailing edge as those of 'normal' mantas do, leading Sehm to consider the possibility that these represent a separate taxonomic form. Equally, however, sometimes genes linked to colour or body pattern also influence the size or shape of an individual (pleiotropic genes), so there is no guarantee that these morphological differences have independent significance.

Moreover, it is known that attacks by other fishes can leave white marks on the dark dorsal surface of a manta. In fact, its dark pigment can even be removed merely by rubbing the surface, creating pale patches. And the elasmodiver website's manta page states that the wing tips often fade to white. Worth noting, incidentally, is that back in the early 2000s this latter site was one of the very few mainstream sources that openly acknowledged the existence of striped mantas, stating at that time: "Dorsum black or dark often with symmetrical white patches forming a chevron across the shoulders".

Intriguingly, Sehm attempted to explain away the white wing tips of Beebe's specimen as an illusion, claiming that what Beebe and his colleagues saw was the white undersurface of the wing tips upraised, fooling the observers into thinking that the dorsal wing tips were white. However, I do not believe this interpretation - the NOAA website's manta unequivocally possesses white dorsal wing tips, as did the specimen that I watched in the whale shark film. Instead, judging from the elasmodiver website's comments, it may be that white-tipped mantas are aged specimens. However, so precise is the symmetry of the white markings on all specimens of striped manta, whether they be wing tip markings, shoulder markings, or chevrons, that this seems unlikely - as do, for the same reason, explanations invoking injury or rubbing as the source of such markings.

In 2005, within a Fortean Times article of mine devoted to these mystery mantas, I expressed the view is that a mutant gene allele was most probably responsible, engendering on rare occasions these stunning and sometimes quite elaborate patterns in mantas - analogous, perhaps, to black-and-white specimens of blackbirds, black bears, crows, and other normally monochromatic species, and creating an additional vision of wonder and mystery amid the breathtaking splendour present beneath the surface of our planet's mighty seas.

Sure enough, thanks to observations and photographs taken of many additional specimens since then, the existence of striped manta specimens is nowadays not only universally accepted among ichthyologists but also, far from constituting a separate species, is deemed to be nothing more than an expression of individual non-taxonomic variation within the long-recognised giant manta species Manta birostris.

Unrelated to such considerations but still worth noting, however, is that in 2009, a second, somewhat smaller, and non-migratory manta ray species, the reef manta M. alfredi, was officially distinguished, named, and formally described – see my Encyclopaedia of New and Rediscovered Animals, 2012, for more details.

But this is not all. In autumn 2014, a mainstream ichthyological discovery was made public via a scientific paper that revealed an exceedingly significant but hitherto entirely unsuspected aspect concerning the true nature of striped mantas. Ironically, however, this crucial find has attracted relatively little attention, especially in cryptozoological circles. Indeed, as far as I am aware, the following documentation of it by me is the first time that this remarkable discovery has ever been referred to in such a capacity, even though it holds the key to these distinctive fishes' very existence.

Published by the Biological Journal of the Linnean Society on 1 September 2014, the paper in question (click here to read it in its entirety) was authored by Csilla Ari, from the University of South Florida's Hyperbaric Biomedical Research Laboratory, and revealed for the very first time that giant manta rays possess the ability to change colour and pattern at will. Ari's study showed that a manta's typical (or, as termed in the study, its baseline) colouration state (i.e. its dark dorsal surface) can change rapidly at feeding times, or if it encounters another manta ray in close proximity to itself, or during intense social interaction between itself and another manta ray. And the precise nature of this colour change is a very noticeable increase in the brightness of hitherto pale, inconspicuous shoulder and pectoral wing tip markings.

In other words, when faced with any of the situations listed above, a typical dorsally-dark manta can transform directly into a striped manta!

Here is the principal Results paragraph excerpted from Ari's paper, detailing this extraordinary manta metamorphosis with reference to various 'before' and 'after' photographs of the mantas (these photos can be viewed directly if the paper is accessed using the above link):

Captive manta rays were observed to undergo rapid changes (within a few minutes) in their body coloration. Specifically, white markings appeared and changed intensity on certain body regions (Fig. 1, 2, 3, 4; the two most representative specimens from each species are shown). The intensity of the white markings would increase rapidly to the ‘intense coloration state’ (Fig. 1D, E, F, G, H, 2D, E, F) more times during the day within a few minutes, and then return to the normal ‘baseline coloration state’. Changes in coloration were observed to occur in temporal proximity to a variety of situations, including at feeding times (Fig. 1H), whenever a new manta ray was introduced to the tank, and during intense social interaction between the two manta rays (Fig. 1G). Feeding occurred twice a day and the rapid coloration changes started shortly (5–10 min) before each feeding on both specimens. The ‘intense coloration state’ was most intense during feeding and slowly returned to the ‘baseline coloration state’ over a period of 20–30 min after the end of the feedings. In addition, rapid coloration changes were observed in association with intense social interaction; for example, when Manta 2 was introduced into the tank or when mantas were chasing each other rapidly and closely, which appeared to comprise courtship behaviour.

In short, the striped manta state was not even a permanent one. Consequently, it would appear that in most if not all cases, such mantas that have been reported and photographed in the past were nothing more than normal mantas exhibiting the temporary pattern and colour transformation ability that had been discovered for their species by Ari. (Incidentally, Ari also revealed that reef mantas possess this same ability.)

The mystery of the striped mantas is a mystery no longer. True, there may be occasional specimens that do exhibit such markings on a permanent basis as an expression of individual non-taxonomic variation, but in most cases such markings would seem to be merely a temporary feature, induced on a non-permanent basis by various fluctuating external stimuli.

Finally: even though we now know the secret of the striped mantas, it is still thrilling when one of these spectacular creatures turns up unexpectedly – and that is precisely what happened to me a second time just last night. I had been watching the 2016 Disney cartoon film Moana, whose storyline was inspired by traditional Polynesian mythology and featured the famous demi-god Maui, when suddenly, in a split-second segment right at the end of the film, an animated striped manta sporting a vivid pair of white shoulder bars and pectoral wing tips soared majestically through the water just beneath the surface. A fitting finale, assuredly, for a movie of magic and mythology to feature a maritime denizen so long associated with mystery and mystification.

Carl Hubert de Villeneuve's sketch of German botanist Philipp Franz von Siebold's captive shamanu, which he had purchased in 1826; sketch produced sometime during 1826-1830 (public domain)

According to traditional mainstream zoology, the shamanu or Japanese dwarf wolf Canis lupus hodophilax was, as its names suggest, a noticeably small subspecies of grey wolf indigenous to Japan (specifically the islands of Honshu, Kyushu, and Shikoku, but not Hokkaido – where a second, much larger grey wolf subspecies, C. l. hattai, once existed instead) but not otherwise significant from an evolutionary standpoint, and was hunted into extinction in 1905.

During September 2018, however, some startling news emerged that very emphatically overturned the first of these two longstanding assumptions.

For that was when, during the International Symposium on Biomolecular Archaeology, held at Jena in Germany, graduate student Jonas Niemann from Denmark's University of Copenhagen revealed that after he and a team of fellow researchers had analysed the genome of a shamanu skeleton from London's Natural History Museum, they had made the startling, highly unexpected discovery that its DNA more closely resembled that of a long-extinct wolf that had lived in Siberia over 35,000 years ago than that of living Eurasian and American wolves, and that the shamanu therefore appeared to be a modern-day relic of an ancient, ostensibly long-vanished group of wolves that had once ranged across the Northern Hemisphere but had hitherto been deemed to have become extinct around 20,000 years ago.

As commented upon by paleogeneticist Mikkel Sinding from the Greenland Institute of Natural Resources in Nuuk, who had extracted the DNA from the shamanu skeleton, this remarkable disclosure could offer a new window on the evolution of wolves, as well as dogs.

Suddenly, a long-held belief regarding the shamanu was no more. But this is not all. Might the second traditional shamanu tenet – that this veritable bonsai wolf became extinct in 1905 – also be disproved one day?

This is by no means impossible, because long after that fateful year, eyewitness reports of small, mysterious wolf-like creatures in various regions of Japan have continued to emerge, encouraging some investigators to become cautiously optimistic that the shamanu may indeed still persist.

I first became aware of and interested in this exciting possibility back in the 1990s, and after researching it I penned an article on the subject, which was duly published in the July-August 1997 issue of the now long-defunct British bimonthly magazine All About Dogs (and contained a delightful colour drawing of a shamanu by Philippa Coxall (now Foster), who illustrated many magazine articles of mine during that decade). As this article may not have ever been seen by readers outside Europe, however, I am reprinting it herewith as a ShukerNature exclusive. Please click on each of its pages to expand it for reading purposes.

 (NB – Since I wrote that article back in 1997, it has been shown that the Arab wolf C. l. arabs is slightly smaller on average than the shamanu, so the latter is no longer deemed to be the world's smallest subspecies of grey wolf; and the shamanu is no longer believed to have existed on Hokkaido.)

My All About Dogs article, of July-August 1997, concerning the possible survival of the shamanu (© Dr Karl Shuker)

My article attracted sufficient interest from readers to inspire me to continue researching this fascinating subject, and in my book The Beasts That Hide From Man (2003) I added some further, more recent information, which reads as follows:

In January 1997, a significant new piece of evidence for the shamanu's putative survival was publicised - a series of recent photographs depicting a dog-like beast that bears a startling similarity to a living shamanu. The photos were snapped on 14 October 1996 by 47-year-old Hiroshi Yagi in the mountain district of Chichibu. He had been driving a van along a forestry road that evening when a short-legged dog-like beast with a black-tipped tail suddenly appeared further down the road. A longstanding shamanu seeker, Yagi reached for his camera, but the animal vanished. After driving back and forth along the road in search of it, however, Yagi saw it again, and this time was able to take no fewer than 19 photos from just a few feet away. He even threw a rice cake towards it, hoping to tempt it closer still, but the creature turned away and disappeared into a forest. When the pictures were examined by eminent Japanese zoologist Prof. Imaizumi Yoshinori, he felt sure that the animal was indeed a shamanu.

In November 2000, Akira Nishida took a photo of a canine mystery beast on a mountain in Kyushu that was widely acclaimed afterwards as evidence of shamanu survival - until March 2001, that is. For that was when a sign appeared on a hut on Ogata Mountain claiming that the creature in the photo was nothing more than a Shikoku-region domestic dog that the hut's owner had been forced to abandon for private reasons. However, Yoshinori Izumi, a former head of the National Science Museum's animal research section, dismisses this claim as a hoax, and remains adamant that the photographed canid is a bona fide shamanu, even stating that the pattern of the creature's fur is completely different from that of Shikoku dogs. This is evidently a saga with many more chapters still to be written!

I have recently discovered online an extensive scientific paper analysing the photographs snapped by Hiroshi Yagi of the so-called Chichibu wild dog, as this mystery canid individual has since become known. Authored by him and Japanese scientist Masazumi Morita, and published by the Japanese journal Animate in 2015, its findings indicate that the creature may indeed have been a shamanu, as revealed by the paper's summary:

Nineteen photographs of an animal "Chichibu wild dog" were taken on 14th October 1996 at the Chichibu mountains. Four of photos that captured artificial structures on the same picture, were analyzed for determination of body, head and face sizes. The estimated sizes were similar to those of a specimen of the Japanese wolf, Canis hodophilax that went extinction in 1905. Based on the results, we applied the super-impose method between the photos of head or whole body and skeletal photos of C. hodophilax specimen. The results showed that the photographed animal approximated to C. hodophilax specimen with appearance, size and shape. It indicated that a canine animal similar to C. hodophilax was present in 1996.

I haven't read any reports of putative shamanu survival lately, but in view of this enigmatic little canid's elevated evolutionary significance and recent outing as a prehistoric survivor of sorts, perhaps it's time that I took up its case once more to search for and publicise any new sightings and accounts that may be on record.

So, watch this space!

Finally: it is nothing if not ironic that perhaps the best known shamanu illustration may not actually portray a shamanu at all. In 1826, German botanist Philipp Franz von Siebold purchased two living canids. One was a genuine shamanu (and was unequivocally depicted by Carl Hubert de Villeneuve; his depiction of it opens this present ShukerNature article), the other was an adult female specimen of a strain of domestic dog familiar in Japan and referred to variously as the yamainu or mountain dog. He made detailed notes and sketches of the two animals, taking pains to delineate their morphological differences.

Notwithstanding this, however, when Dutch zoologist Coenraad Jacob Temminck subsequently consulted Siebold's notes while preparing his own documentation of the shamanu for his great work Fauna Japonica (1833), he somehow confused the two different canids, ultimately synonymising them as one and the same form. Consequently, there has been much controversy and conjecture ever since as to whether the shamanu illustration in his work does indeed depict a shamanu or whether it is instead based upon the mountain dog. Nevertheless, this image has been reproduced and presented as a bona fide shamanu representation in many later publications, making it the most (in)famous shamanu picture ever.
