The Patamakanthin's Shell World-Sharing the Love of Shelled Molluscs

It is a sweltering noon on Christmas Day in Phuket's newly opened Jungceylon Shopping Mall, located in the tourist district of Patong Beach. Rows of upper-end coffee shops and retail outlets line both sides of the open air, street style mall. The air is thick with celebratory music blaring from the loudspeakers of a nearby fashion and design show. Coupled with the endless crowd moving across the plaza in all directions, one might wonder why I would be interested in this highly anthropogenic environment. But I am here because of a very special person, a person that has been on my must-see list for years.

"Welcome to Phuket!" exclaimed Jom Patamakanthin, as he let us (my family and me) into his golden-bronze Isuzu 4WD. Fresh from a busy schedule of meetings and office work,  Jom has made extra effort to personally pick us up from our hotel to his museum. Earlier on, he has even arranged the hotel's room prior to our arrival in Phuket! Surely, he must be packed full of enthusiasm to welcome us with such kind hospitality! And as I discover later, what brimful of enthusiasm he has!

Born to a father who treasures every piece of shelled-mollusc and a mother who relentlessly encourages him to pursue his interests, Jom is literally given the position to hold the baton as one of Thailand's leading shell expert. Jom's father, Somnuek Patamakanthin, has been the household name in not just shell-collecting circles but also in the fields of conchology and malacology within and beyond the shores of Thailand. This is due to his interest in shell collecting since he was a child, 50 years ago. His helpful and friendly nature has enabled him to exchange shells with like-minded hobbyists as well as donating his specimens to scientists for research purposes. It is such rare opportunity that has allowed him to bridge the often divisive gap between marine scientists and shell collectors. In fact, Somnuek's contribution extends beyond science and hobby.

"You see the logo up on that building?" Jom pointed to a large shopping centre while driving through the central Phuket region, "That's Stellaria solaris, the Sunburst Carrier Shell," he revealed. Jom related that few years ago, his father generously borrowed the designer of the Central Festival Shopping Centre many of his shell books to draw inspiration for the mall's logo. Besides the logo, Somnuek's generosity has also given the designer ideas on the mall's interior decor.

Of course, there's no doubt that Jom has been heavily influenced by his father. Being a self-taught scholar with a peculiar taste for an unorthodox way of learning, Jom has surprised his peers with his high academic results. "People kept asking me," Jom recalled, " 'Hey Jom, how do you study in such a crowded place?' ", referring to his favourite haunt- the shopping malls. "Focus..... and commitment," Jom quipped with a smile.

Perhaps that is the philosophy that is fueling his enthusiasm in shells. Jom has been exposed to the world of shells since childhood but it had never occurred to him that it will play a big part of his life soon. The moment came when Jom was introduced to the shell trade and exchange arena in his early teenage years. "It is the moment that I said to myself 'This is my future!' " Jom remembered. He started to extend his social circle into both the shell-enthusiasts and the scientific community, mirroring his father's move. In the years since then, Jom and Somnuek have their names honoured by having many new species and subspecies named after them, such as Conus patamakanthini (Delsaerdt 1997), Alycaeus somnueki (Panha & Patamakanthin 1999), Haliotis ovina f. patamakanthini (Dekker, Regter & Gras, 2001) and Epitonium patamakanthini (Gittenberger & Gittenberger, 2005).

But arguably the biggest contribution the Patamakanthins have on the molluscan world is the Shell World, a collection of museums that house tens of thousands of species of shelled molluscs, ranging from the downward minuscule to the goliaths of shells. Having spent years exchanging specimens and information between friends, the father and son decided to shift their paradigm to a new level- to bring the world of shelled molluscs to the general public. Utilising their enormous wealth of specimens from their collection, they laboriously studied and prepared thousands of exhibits.

In November 1997, Somnuek founded the first private shell-museum in Thailand (and probably the only one in this part of the world) with his brothers and sisters. Located in the popular Rawai district of Phuket, the Phuket Seashell Museum made waves across the world's mollusc-loving community. It has earned the praise of many as being among the best private and shell museum in the world. Not long after, Jom endeavoured an ambitious plan to extend his family's enterprise by establishing another shell museum in the popular resort island of Sentosa, Singapore. He spent many days designing and outlining the exhibits for his future museum. Alas, his plan collapsed due to difficulties with land issues. Not intending to back down, he started anew back in his country. Along with his shell-collecting friend, Ms. Oraphin Sirirat, Jom established the Bangkok Seashell Museum. By now, the Patamakanthin's labour of love have been recognised by many who had visited and been awed by their treasured collection.

Recently, Jom announced that he will continue to seek new locations fit for more shell museums, which led me to one question everyone's eager to find out: Why build so many shell museums? To that, Jom answered with such down-to-earth honesty and humility, "I'd like to share my knowledge with everyone......and to make and meet new friends along the way."

The entrance to Jom's newest shell museum in the newly opened Jungceylon Shopping Mall, Patong, Phuket. Note the gate's design is inspired by the spider conch, Lambis sp.

The sheer number of species and specimens on display easily outnumber an exhaustive list of superlatives fit for describing it!

The museum display starts with the nolluscs of a bygone era, such as this precious assemblage of Morroccan Nautilus, Cenoceras sp.


The multitude of fossil molluscs in display is an accumulation of specimens from years of exchange with friends from all across the world.

Looks like the shell museum has plenty to satisfy aspiring paleontologists too, with ammonites from various ages.

Jom also has a collection of curious marine-life encrusted objects. "Sometimes, beauty comes in unexpected forms," he said.

Even a collection of all known species and subspecies of present day living nautiluses (the "living fossils") are on display, many of them rarities such as Nautilus macromphalus (Sowerby 1849) and Allonautilus scrobiculatus (Lightfoot 1786).

Even rarer than nautilus, the slit shells (family Pleurotomariidae) is another group of living fossils dating back to more than 500 million years ago. the "wow" factor here is: the sheer number of specimens (and species) on display.

Sitting on the pinnacle of the slit shell section are these two giants-where old meets new. On the left is the world's largest living species, Entemnotrochus rumphii and on the left, a fossilized pleurotomarid.

Jom recalled that his friend found this extremely well-preserved fossil in a French limestone formation many decades ago. He had been waiting for the right time and technology to appear before extracting the shell from the limestone. With cutting edge 21st Century technology, he employed professional jewellery craftsmen to laboriously chip out the deposit and polish the fossil.

Jom also has a keen eye on any variations within a species, bringing seemingly common species such as these Trochus niloticus into new light. he even has a subfossil of the species (on the bottom right corner) unearthed from Phuket itself!

Turbans and Stars (shells, that is) of many species on display.

Arguably, the show-stealer of the day would be this amazing rotor blade-like variant of Angaria sphaerula (Kiener 1839).

The striking colours of so many scallops (family Pectinidae) on display baffles even the most seasoned of shell admirers.

A closeup of the candy coloured scallops of Lion's Paw, Nodipecten fragosus (Conrad 1849).

A mountain of spectacular thorny oysters, Spondylus versicolor (Schreibers 1793).

Another eye-popping spectacle is this metres high pile of Squamose Giant Clams, Tridacna squamosa. In case if you're wondering where on earth did Jom manage to get this much, this pile is retrieved from a collective number of decades-old shell middens (the place where shells are dumped after meals) along many of the Andaman coastal villages with the permission of Thailand's Fisheries Department.

A beautiful collection of porcellanous Turbinella fusus, the much rarer cousin of the Indian Chank, Turbinella pyrum.

Frogs (family Bursidae) and Tritons (family Ranellidae) are among the group of giants on display.


Comb murexes are one of those iconic shells that often graze beach-themed advertisements.

Jom even has a collection of large abalones (family Haliotidae) including the famous Californian Red Abalone, Haliotis rubra.

Bonnet shells (family Cassidae) displaying the multitude of species within its family.

The museum isn't just home to any shells. Many of its exhibits are in fact rare and endemics, euch as these "Glory Cone Shells" which includes Glory of the Seas Cone, Conus gloriamaris (Chemnitz 1777); Glory of Bengal Cone, Conus bengalensis (Okutani 1968); and Glory of India Cone, Conus milneedwardsi (Jousseaume 1894), among others.

Another family of many rare and endemics, the volutes (family Volutidae) are well known among shell enthusiasts.

But perhaps the most popular of all shells is the cowries (family Cypraeidae). Seen here are the rarest specimens of all: the Zoila Cowries, Zoila ketyana (Raybaudi 1978) (centre bottom); Melanistic cowries (the dark tint is a result of living in waters tainted with heavy metals) (left and right) and the "King and Queen of Cowries", as Jom puts it, the rostrate (deformed, curved up) money cowries, Cypraea moneta (centre top).

Clams such as these are unexpectedly gigantic!

There's even a section dedicated to non-marine molluscs, an often overlooked part of the world of shells. Seen here are the unbelievably beautiful Polymita landsnails, Polymita picta (Born 1778). (far from those drab looking snails in your garden!) Underlying the aesthetics, this group of snails is among the best candidate for demonstrating variation's role in the evolution of species. 

More candy-looking landsnails- Indonesia's Asperitas and Chloritis (centre right) and Papua's Papuinas (bottom left).

Just like landsnails, freshwater clams like these (mostly of family Unionidae) demonstrate speciation (species formation) with their endless forms of variants.

But perhaps the most surprising of freshwater molluscs would be this seemingly thalassoid (marine like) freshwater snail Tiphobia horei from Lake Tanganyika, East Africa.

Jagged Mountains, Hidden Tiger-Krabi's Tiger Cave Temple (Wat Tham Seua)

 
A view of a tropical limestone karst in Krabi.

The mention of tropical limestone karsts often invokes images of majestic geological monoliths of towering heights, draped in lush emerald vegetation interspersed with the oft-exposed dolomite cliffs tainted to shades of earth and soot by the accumulated detritus from calcicolous cliff-hanging plants. And if the tropics in conversation refers to Southeast Asia, a handful of locations spring to mind-notably: Vietnam's Halong Bay, Laos' Luang Prabang Karsts, Malaysia's Mulu Caves and Thailand's Andaman Coast, among others.

The town of Krabi as viewed from Wat Tham Suea's peak temple.

In this collection of breathtaking locations, the quaint town of Krabi smacks right at the heart of the Land of Smiles' heavily-touristed Southern Provinces. This peaceful town is undeniably synonymous with limestone towers; more so after the widely published panorama of Koh Hong and Koh Phi Phi, islands off the shore of mainland Krabi, which characterise in stunning cliff-islands in turquoise waters that defies imagination and borders on fantasy.

Limestone hills adorn the lands beyond Krabi as seen from the Wat Tham Suea.

Up on land, the jaw-dropping factor does not ebb as cultivated lowlands give way to gigantic karsts rising hundreds of meters into the sky. One of these towers is home to the sacred Wat Tham Seua (Tiger Cave Temple). Spotting this temple is not a difficult task as its conspicuous gold Buddha and Stupa can be seen perching atop the mountain's peak from miles away. The fact that this temple is connected to the base of the karst via a very long series of steps opens up the possibility for the public visiting it for religious and aesthetic reasons (that is, its commanding 360 degree view of the plains below and mountains beyond), as well as (in my case) to study the hill's interesting ecology.

The stairs leading to the hilltop temple is dizzying and considering the terrain and height on which it is built, one wonders how people managed to achieve such a construction feat.

It is rare that researchers could have a chance to examine a tropical fengcong-fenglin karst right from the mountain's base up to the very tip of its peak.  An opportunity in the form of the 1237 steps to the hilltop temple greatly enhance accessibility for scientists to analyse every layer of ecological niches in reference to altitudinal changes.

While ascending this unmistakably long flight of stairs, most people will first notice the steep and rather thin steps in sections along the way. Coupled with the dizzying heights and almost vertical cliffs, ascending the mountain may be the last thing on an acrophobe's mind. However, with endemic and rare wildlife and plantlife adorning its marble cliffs, enthusiasm eludes fear of heights!

The following is a list of interesting things found during the survey:

An unidentified shrub, most probably a calcicolic (limestone-loving) plant.

Chrita spesies, this genus belongs to the family Gesneriacea, which includes many ornamental plants including the African violets.

Paraboea sp., a perennial plant which leaves will dry during dry seasons and regenerate when rains arrive.

More unidentified plant!

Even more!

This herb is another limestone-loving plant similar to that found in Gua Kandu about a year ago.

A long tailed macaque (Macaca fascicularis) belonging to a resident troop which resides along the lower levels of the stairs. These guys know how to get downhill the fast way-by sliding down the railings!

Another Paraboea sp. Paraboeas are limestone specialists and can be found across mainland Southeast Asia.

More Chrita sp.!

An unidentified Paraboea(?). This species was also discovered by the author of this blog: Hort Log.

This is the unmistakable limestone-loving plant- Monophyllaea sp. It is a limestone-endemic genus and  the Sundaland region is its epicenter.

Another Chrita sp. This genus seems to be common in southern Thailand's karsts.

An unidentified grasshopper on limestone soils. Some insects on these hills are endemic because of their specialised adaptation to the unusual karst environment.

More identified species. This one is found on exposed rock face some 100 metres above ground level.

The weathered limestone exhibits craggy texture encrusted in dark moss and lichen carpets. These crevices are prime habitats for endemic micro-land snails.

More Chrita sp.! This time, of a maroon leaved variety. Is this the same or different species from the previous Chrita plants?

A breathtaking view of the oil-palm covered plains below-A perfect way to take a breath after the laborious climb.

Another unidentified plant!

Another Chrita species, of dark purple flowers?

A dark limestone pinnacle.

A closeup of another limestone pinnacle. Note the sharp edges of the weathered rock.
This is the primary barrier to exploration on limestone hills.

A limestone bamboo species,Dendrocalamus sp., which lives some 100 metres short of the karst mountain's exposed peak.

Another endemic, Pandanus calcis, which is found only on the karsts from Surat Thani (in the north) to Krabi (in the south). This specimen is flanked by the Dendrocalamus bamboo.

Another specimen of the Calcicolic Pandan mentioned above. Note that this is a cousin of the popular herb Frangrant Pandan or Screwpine, Pandanus amaryllifolius, which is used in Southeast Asian cuisine as an aromatic condiment.

An unidenified fern flank by Paraboea sp., on weathered rocks.

Another Gesneriacid (meaning a member of family Gesneriacea,), clinging to a rock crevice.

An unidentified plant living on the edge of the cliff face near the mountain peak.

Anothert plant belonging to the species seen earlier.

A Capparis sp.(?) found living on limestone at the side of the peak temple.


An insect found on the peak temple.

Of course, as any exploration of limestone localities, a dash of molluscan flavour to the tastes of discovery is not far away. With such variety of endemic and rare flora, comes a list of terrestrial snails of equal status.

A set of macro molluscs found during the survey. Species includes: Cyclophorus zebrinus,Hemiplecta siamensis, Macrochylamys amboinensis, Rhiostoma smithi and Plectopylis achatina.

Cyclophorus zebrinus (Benson 1836)

 
Hemiplecta siamensis (Pfeiffer 1856)

Rhiostoma smithi (Bartsch 1932)

Rhiostoma smithi (Bartsch 1932), apertural view.

Plectopylis achatina (Gray 1834)


Coming back to the aesthetic side of things, the final 1237th step is as great a welcome as the cool drinking water served. Coupled with commanding vistas of the Krabi country sprawling before my exhausted eyes (after straining for 2 whole hours, searching for calcicolic (limestone-loving) critters!), this could easily be one of the best limestone-hill climbs around.

A view of the hilltop temple; notice the weathered limestone pinnacles on which the temple is built on and around.

Looking across a forested saddle (a lower area connecting two limestone peaks) from the hilltop temple, one could see the profuse vegetation adorning the cliffs of another peak.

Stunted trees reminiscent of bonsai plants clinging to the shallow soils and crevices of the limestone peak.

The stark contrast between cultivated plains and forested karsts that are so common in Krabi is evident from this view to the East.


As for how the temple got its name, I'll leave that for you to find out!

PS: Due to the difficulty in accessing information on Southern Thailand's limestone flora species, I have only resorted to the following sources for information. Please do inform me if you have any useful information on the above plants' identification. Your help is greatly appreciated!
