Yesterday (15th May 2010) the internationally renowned snake and arachnid collections of the world famous Instituto Butantan, Sao Paulo, Brazil were destroyed by fire.

This is not just a tragedy for the devastated researchers based at Butantan and the many international visitors they receive each year, this is from a scientific standpoint, a disaster with international ramifications which will have a long lasting effect similar to the bombing of the Berlin Museum during WWII, with the subsequent loss of important specimens and papers that caused.

To a non-scientist it is hard to understand why the loss of a few thousand jars of pickled snakes should be important. So to explain.

Every species is described using a type specimen and it is that specimen that holds the name of the species, and if that specimen is lost or destroyed it makes validating species difficult, such as determining whether a newly found specimen belongs to the same or a new species. Type specimens are the bedrock of taxonomy (the science of naming species which supports biology and conservation), they are protected and cossetted and kept from harm, whenever harm threatens. During WWII all the type specimens in the British Museum (Natural History) were removed to safety underground.

Sadly nobody at Butantan could have forseen the disaster that was about to befall them, so irreplaceable type specimens have been lost along with the rest of the most important and influencial herpetological collection in Latin America.

From Wikipedia: On May 15, 2010, a fire gutted the building of collections and destroyed about 70 000 specimens of snakes, scorpions and spiders preserved in formaldehyde. Over 90 years of research were lost. The fire started at 7 am and was controlled only an hour and a half later. According to initial assessments had not animals living in the building.

This was not the building destroyed by fire.
Lost was the spirit collection building, housing some
70,000 preserved snakes, spiders and scorpions,
many collected in the early 20th century,
and many type specimens for their species.

I visited Instituto Butantan in 1987 whilst working on the Royal Geographical Society "Maracá Rainforest Project" (see below) and then filmed there and with colleagues from Butatan on Ihla Queimada Grande when we made the OBA film "Lost Worlds" in 1999, when we also collected a specimen of the, then still undescribed, Alcatraz lancehead.

My sympathies go out to everyone at Instituto Butantan following this terrible disaster.


Brazilian television report

Youtube footage

It seems another Brazilian herpetological institution is under threat and needs help.

I have received an email from Dr Rodrigo Souza, Director of the Serra Grande Breeding Center for Lachesis muta rhombeata.

This is the critically endangered Atlantic coastal bushmaster, a separate subspecies from the one in the Amazon. Everybody knows the Amazon is endangered but few people realise that the thin coastal forest of Brazil is even more threatened by the advance of man. It has been suggested that 93% of the forest has gone, it certainly only remains as pockets on mountains and hillsides. These forests were home to many strange and unique species, some of which (golden lion tamarins, Spix's macaw) appeal to the public and are considered 'worthy of conservation'. Others might not appeal quite so widely, Cropani's boa (Corallus cropani - see above) and the venomous Atlantic coastal bushmaster. Rod Souza, a medical doctor, has devoted his life and livelihood to conserving and breeding the bushmaster but he is now running out of funds.

The Atlantic coastal bushmaster was the subject of the first ever OBA film, entitled "Ox Killer"*. We spent 10 days and night scouring three states (Rio de Janeiro, Bahia and Alagoas) and on the final night, at half-past midnight, at a remote protected location called Quebrangulo, we found a male Atlantic coastal bushmaster. The snake had only emerged because it had rained that afternoon and evening. We were elated, first film in the can, and we continued to succeed for the next eight films. OBA went to four series' but in the five years that it took to make the films, the bushmaster has continued to struggle for survival.

Rod Souza's breeding project may be its only life-line beyond re-establishment of vast swathes of original rainforest, yet deforestation continues year by year. Souza considers the bushmaster may even be extinct in the wild, in which case his project is truly its last chance.

* Ox Killer was not my choice of title. It is an Anglicization of the Costa Rican name 'matabuey' which refers to a different species of bushmaster which is claimed to kill oxen. I would have selected a more sympathetic title that did not demonise an endangered species.


Support the Resolution being voted on at the Royal Geographical Society SEM on 18th May 2009

The Royal Geographical Society was once synonymous with exploration and expeditions. During the 1970s and 1980s the RGS mounted a series of large-scale, multidisiplinary expeditions to some of the remotest parts of the world. Since then the Society seems to have turned its back on conducting its own expeditions. A significant number of Fellows wish to see a return to the heydays of the Society, they want the Society to once again mount large expeditions. However, the current RGS Council is against this return to large-scale expeditions. A Special General Meeting has been called for 18th May. If you are a Fellow or a Post-graduate Fellow of the RGS you can vote for the Resolution. If you are an interested member of the public you can voice your opinions and offer your support on The Beagle Campaign website.

Mark O'Shea has been FRGS for over 20 years and was the herpetologist on one the the RGS's most successful expeditions, the Maracá Rainforest Project in northern Roraima, Brazil, during 1987-1988.

Bound for New Britain (May 2008)
Snakebusters PNG 2008 pt.4

Dave was due to fly to Jakarta to present our paper on Snakebite in the Asia-Pacific Region, at a WHO conference, and I had been invited to visit the Dami oil-palm estates in West New Britain Province. I was very keen to go, there might not be any dangerous venomous snakes over there but there was a python I was particularly keen to see in the wild. This would be my first ever opportunity to search for the Bismarck ringed python, Bothrochilus boa, probably the least python-like of all New Guinea pythons, and although my visit was short, only a few days, I was thoroughly looking forward to it.

The Search for Papa Graun Moran (May 2008)
Snakebusters PNG 2008 pt.3

There are five highlands provinces in Papua New Guinea, the largest being Southern Highlands Province. I first visited in 2000 whilst filming part of an episode of O’Shea’s Big Adventure in Tari. In 2008 David Williams and I were traveling up to Moro on the northern shore of Lake Kutubu to conduct an herpetological survey for Oil Search Limited and the World Wildlife Fund. Our aim was to initiate a survey of the only fully protected snake in Papua New Guinea, the Boelen's python, Morelia boeleni, known locally as papa graun moran (father ground python).

Island of the White Snake (April-May 2008)
Snakebusters PNG 2008 pt.2

Madang Province is one of the northern coastal provinces of PNG, and one of the more attractive and verdant parts of the country. I first came here in 1990 when I was based at the, now closed, Christensen Research Institute (CRI) on the northern coast road about 14mls north of Madang town. I was working with Oxford University’s Department of Clinical Medicine, as the herpetologist with the otherwise medical team and had come to Madang to capture the elusive but highly venomous New Guinea small-eyed snake, Micropechis ihaheka, for venom and snakebite research. Locals call this much feared snake, which can achieve lengths of over 2.0m, the wait snek (white snake) because of its light coloured body colour which contrasts with its dark head and the red-brown body rings.

Snake Quest in the Wild West (April 2008)
Snakebusters PNG 2008 pt.1

Located in the southwest of Papua New Guinea (PNG), up against the border with West Papua (Indonesia), Western Province is the largest PNG province with a surface area of 99,300sq.km. (38,340sq.miles), but a population of only 153,000.
This is a remote region of mangrove and freshwater swamps, monsoon forests, seasonally flooded grasslands and huge crocodile-infested rivers ie. the Fly, Strickland, Bensbach, Mai Kussa, Oriomo, Bina Turi, Paho Turi. There are few roads and most travel is by boat along the rugged coast or inland up the rivers. The administrative centre, with a population of 15,000, is tiny Daru Island a few kms off the southeastern coast, the only place no in danger of complete inundation during the wet season. Western Province easily earns the nickname of Papua New Guinea’s “Wild West”.

Australian Venom Research Unit,
Papua New Guinea Snakebite Project
(March 2008)

Mark O’Shea has been working in Papua New Guinea since 1986.
He conducted herpetological surveys for Operation Raleigh in Western and Central Provinces. He then conducted venomous snake research and worked with medical professionals in Central and Madang Provinces, on the joint Oxford University Dept. of Clinical Medicine – Liverpool School or Tropical Medicine – University of PNG Dept. of Medicine snakebite research project through the 1990s and wrote the definitive A Guide to the Snakes of Papua New Guinea (Independent Publishing, Port Moresby, 1996). In 2000 he presented three films: Green Blood, Magic Man and Tree Crocodile, in the 2nd series of O’Shea’s Big Adventure, filming in Central, Western, Madang, Simbu, Southern and Western Highlands Provinces. In 2006 he launched a set of six stamps featuring the Dangerous Snakes of Papua New Guinea, which he designed for PostPNG (these stamps are available in special packs from the shop on this website).

Mark was back in PNG, under the auspices of a Fellowship from the Dept. of Pharmacology at the University of Melbourne, to work as a member of the small Australian Venom Research Unit (AVRU) team with David Williams (AVRU) and Dr Wolfgang Wüster (University of Bangor) and alongside colleagues from UPNG Dept. of Medicine and Australian institutions.

Papua New Guinea has a snakebite problem.
Although neighbouring Australia (pop. 20M) suffers only 2-3 annual snakebite fatalities, PNG (pop. 5.5M), with many of the same or related venomous snake species, suffers at least 200 and possibly as many as 600 snakebite fatalities a year. PNG spends 25% of its medical drug budget on Australian antivenom and still runs out of stocks. Combined with corruption, theft and black-market resale of Australian antivenom within PNG, and the importation and sale of useless, even dangerous, foreign antivenoms, at vastly inflated prices, snakebite must feature as one of the most serious medical emergencies faced by Papua New Guinea.

In some parts of the country more people die of snakebite than malaria, TB or HIV/AIDS.

The AVRU team, led by David Williams, is determined to bring down the death rate through snakebite, work towards the production of cheaper and more efficient domestic antivenoms and reorganise the antivenom distribution system so that every snakebite victim has a chance of survival. To this end it is necessary to capture live and healthy specimens of the species responsible for causing snakebite across the country. In three short fieldtrips to Milne Bay, Oro and Madang Provinces in late 2006 Mark and David captured ten Papuan taipan, four New Guinea small-eyed snakes, a dozen death adders, two Müller’s crowned snakes and the first three New Guinea brownsnakes available from venom research.

But this work is not without risk.

This site is currently being re-organised and improved to incorporate the four films from Series 4 (Africa and S.America), filmed during 2003, and updates on the projects contained in the previous three series'. Please check back soon.

Mark’s “Big Adventure” began in 1998 when YAP devised a series featuring the herpetologist Mark O’Shea for Channel 4 in the UK and Animal Planet in the US.
Since then Mark and the YAP team have travelled to some of the world's most exotic locations, encountering some of the planet's deadliest and most fascinating reptiles and amphibians.
From Arkansas to Argentina, India to Indonesia, and New Guinea to New Caledonia, Mark has come face to fang with king cobras, beaked seasnakes and silent rattlesnakes. He’s got up close and personal with snapping turtles, snappy gators and cryptic crocs. And he’s rubbed snouts with Komodo dragons, giant geckos, and skinks with an “extraterrestrial” twist.
Risking life and limb Mark dives deep into the ocean, climbs mountains and volcanoes, and probes the deepest jungles, driest deserts and steamiest swamps in pursuit of his elusive quarry.
Everything you see on the programme happens for real. No captures are stage managed, no creatures caught twice to facilitate filming.

What you see is what we got!
Now a series of special one hour adventures is currently in production. Over the coming weeks the site will be added to with new photographs and information about these films…as well as updates on the existing pages.
In the meantime explore some of the earlier ground breaking programmes, and don't forget to bookmark this site before you enter Mark O’Shea’s fascinating world of reptiles.
