Cold Snap Killed Many Pythons in Everglades
Feb 15th
Pythons, iguanas, non-native fish died in January freeze
Excerpt from the Sun Sentinel’s Cold snap kills pythons
Vultures circled over Everglades National Park’s Anhinga Trail, where thousands of dead non-native fish floated in the marshes.
About half the Burmese pythons found in the park in the past few weeks were dead.
Dead iguanas have dropped from trees onto patios across South Florida. And in western Miami-Dade County, three African rock pythons — powerful constrictors that can kill people — have turned up dead.
Although South Florida’s warm, moist climate has nurtured a vast range of non-native plants and animals, a cold snap last month reminded these unwanted guests they’re not in Burma or Ecuador anymore.
Temperatures that dropped into the 30s killed Burmese pythons, iguanas and other marquee names in the state’s invasive species zoo.
Although reports so far say the cold has not eliminated any of them, it has sharply reduced their numbers, which some say may indicate South Florida is not as welcoming to invaders as originally thought.
“Anecdotally, we might have lost maybe half of the pythons out there to the cold,” said Scott Hardin, the Florida Fish and Wildlife Conservation Commission’s exotic species coordinator. “Iguanas definitely. From a collection of observations from people, more than 50 percent fatality on green iguanas. Green iguanas really got hit hard. Lots of freshwater fish died; no way to estimate that.”
The cold snap has played into a highly politicized debate over how to prevent non-native species from colonizing the United States. Reptile dealers and hobbyists strongly oppose a proposal by the U.S. Fish and Wildlife Service to ban the import of and interstate trade in Burmese pythons and several other large snakes. They say South Florida’s cold snap shows these species don’t threaten to spread north, as some claim, and a federal crackdown is unnecessary.
“Pythons are tropical animals,” said Andrew Wyatt, president of the United States Association of Reptile Keepers. “When temperatures fall below a certain level, they are unable to survive. It reinforces the idea that the pythons can’t exist more than a short period of time north of Lake Okeechobee. Even the pythons in the Everglades are dying during the cold snap.”
Wyatt said scientists are downplaying the effect of cold weather on the pythons because that would undermine their ability to win grants to study a problem that has received international publicity
Bear Market in Boas

Premium Python, Once Worth $40,000, Now Sells for Half; ‘It’s Just Like Stocks’
Excerpt from the Wall Street Journal’s Bear Market in Boats
CHICO, Calif.—The stock market is back on track, and bond markets are open for business. But now, another inflated financial market is facing collapse: mutant pythons and boa constrictors.
Early in 2009, “investment grade” big snakes—critters with genetic mutations that create rare colorings—still held their premium values. But since last spring, the mutant-snake bubble has burst.
More photos and interactive graphics Premium pythons that could fetch $40,000 in 2007 now go for half that sum, breeders report. The price for a hypomelanistic boa constrictor, one with a mutation that lightens its skin tone, was $99 on Feb. 1, down from $5,000 in 2007, on Kingsnake.com, a classified-ad site that acts as a market-maker for snakes.
Ron Greenberg, a retired fiberglass-plant manager who keeps 1,000 snakes here in Chico, says demand has disappeared altogether for some boas he breeds. He can’t find buyers anymore for “sunglow” boa constrictors, which sport an unnatural reddish-orange-and-off-white coloration, and fetched $3,000 two years ago.
The turning point: Senate Bill 373, which Florida Democrat Bill Nelson proposed in February 2009 to prevent situations like one in the Everglades, where escaped Burmese pythons have devoured native animals. The bill would ban importation and interstate transport of boa constrictors, anacondas and large pythons. A similar antisnake bill followed in the House.
California Snake Breeder Is Feeling Squeezed

Federal lawmakers want to ban the interstate sales of boa constrictors and some pythons, to keep escaped snakes from eating native animals. But breeders like Ron Greenberg say the restrictions could bankrupt them. WSJ’s Justin Scheck reports.
Neither bill has passed yet, but “no one is willing to give me $10,000 for a snake when they think they may be added to an injurious-species list,” says Mike Wilbanks, 41 years old, an Oklahoma python breeder.
The boa bear market comes after years of growing demand for constrictors with genetic mutations that result in abnormal colors. A normal ball python today typically sells for under $100; a “piebald” python—white with rare blotches of brown and green—can fetch $3,000.
The rarer the mutation, the more expensive the snake, and investors paid huge sums for snakes that could produce babies that brought big returns. Adam Wysocki, a Maryland computer programmer, sold his house in 2006 and spent $40,000 on a rare “lesser platinum” ball python. He had money to invest, he says, but he “wanted to do something with it that was more than investing in Microsoft or something.” In 2007, he says, three of the prized snake’s young sold for $18,000 each.
Last year, Mr. Wysocki’s most expensive snake sold for just $7,000. While the relatively small ball python isn’t on the Senate bill’s trade-ban list, the market for it has been depressed, he says, because investors are afraid the snake will be added to the list.
The origins of the snake bubble harken back to the early 1980s, by many breeders’ accounts, after Florida reptile breeder Tom Crutchfield recognized a photo of an albino Burmese python in National Geographic magazine.
Mr. Crutchfield, looking to breed the snake, convinced a New York reptile trader to import the albino python and two of its siblings. To pay the $21,000 for the snakes, Mr. Crutchfield took a second mortgage on his house. He rented out one python for a $10,000-a-year stud fee and says he later sold about 40 of the three snakes’ young for $5,000 each.
The mutant-constrictor economy began to resemble the Dutch tulip mania of the 17th century, as snake speculators entered bidding wars for rare specimens, which they began calling “investment grade.” Buyers would then breed their own young mutants, selling them at high prices to other speculators who hoped to breed and sell to still others. “It’s always been a pyramid thing,” says Mr. Crutchfield who, after pleading guilty to charges related to illegal reptile smuggling, is back in business at age 60. “The people at the top make the most money.”
As rare-colored snakes reproduced and the mutation grew more common, sell-offs caused prices to drop. But there were always new mutations that sold for outlandish prices while scarce.
Tom Burke, a 55-year-old former tugboat driver in Long Island, expected his snake investments to be a fallback during the recession. Mr. Burke says his snake sales went up in late 2008, even as the rest of the economy crumbled.
Mr. Burke explains mutant-boa business economics thus: In 2008, an albino male boa and a motley female with an albino gene cost $1,000 for a pair. Within 30 months, the pair would likely produce at least five motley albino young, which sold for $1,500 each, at 2008 prices. Minus $1,000 or so in equipment and rats and mice to feed the snakes, profits would still be greater than 100%. “People who want to diversify their income or get a better income or a higher income, they do this,” Mr. Burke says. “It’s just like stocks.”
Like stocks, the snake market proved susceptible to sentiment. After Sen. Nelson introduced the snake bill, Mr. Burke says, demand dried up. Mike Panichi, a Brooklyn homicide detective who in 2005 borrowed from his retirement fund to invest in boas, says he got frequent inquiries from prospective snake buyers until early 2009. But now, he says, there’s “zero interest.” The snake market took another hit last month, when Interior Secretary Ken Salazar separately proposed adding several constrictor species to the “injurious wildlife” list that cannot be imported or carried across state lines.

Ron Greenberg, who keeps 1,000 snakes in Chico, Calif., says demand has disappeared for some snakes, like this albino Burmese python.
Bryan Gulley, a spokesman for Sen. Nelson, says he feels for the breeders, but says big snakes can be dangerous. He points to a 12-foot anaconda that was found last month in a Florida pond with a goose in its gullet, and a pet Burmese python that allegedly strangled a Florida toddler to death in July.
Snake breeders counter that most pet constrictors are less dangerous than a large dog. Andrew Wyatt, president of the U.S. Association of Reptile Keepers, testifying on Capitol Hill against antisnake legislation, said that captive boas and pythons “are not the dangerous killers portrayed by activists in the media.”
Mr. Wysocki, the Maryland breeder, has been selling his collection to fund a lobbying organization he calls the National Pet Association. The NPA is trying to rally people outside the snake community to oppose the Senate snake bill on the grounds that it could be a slippery slope toward restricting dogs and cats.
“What they don’t realize is the economic impact this is going to have,” says Mr. Crutchfield, the albino-python pioneer, who notes that the constrictor crunch will squeeze suppliers of snake food, too. “What about the guy who sells rats? Who’s going to buy jumbo rats?”
Good question, says Bill Parker, owner of Feeder Mice Unlimited in Oroville, Calif. Mr. Parker, 76, raises about 40,000 mice and rats on a former catfish farm. His company brought in almost $300,000 in 2008, he says, mainly from reptile enthusiasts. But last year business was down about 30%, and he had to lay off three employees. If the Senate bill passes, he says, “that will kill us.”

Herpetology Defined
Feb 6th
Herpetology is the branch of zoology concerned with the study of amphibians (including the frogs, toads, salamanders, newts, and gymnophionae) and of reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras).
Herpetology is concerned with poikilothermic, ectothermic tetrapods. “Herps” (or sometimes “herptiles” or “herpetofauna”) include reptiles and amphibians, but exclude fish. However, it is not uncommon for herpetological and ichthyological scientific societies to “team up”, publishing joint journals and holding conferences in order to foster the exchange of ideas between the fields. One of the most prestigious organizations, the American Society of Ichthyologists and Herpetologists, is an example of this. Many herpetological societies exist today having been formed to promote interest in reptiles and amphibians both captive and wild.
Herpetology offers benefits to humanity in the study of the role of amphibians and reptiles in global ecology, especially because amphibians are often very sensitive to environmental changes, offering a visible warning to humans that significant changes are taking place. Some toxins and venoms produced by reptiles and amphibians are useful in human medicine. Currently, some snake venom has been used to create anti-coagulants that work to treat stroke victims and heart attack cases.
The word “herpetology” is from Greek: ἑρπετόν, herpeton, “creeping animal” and -λογία, -logia. People with an avid interest in herpetology and who keep different reptiles or amphibians, often refer to themselves as “herpers.”
Salmonella Risk Reduction
Feb 2nd
Excerpt from “Reducing the risks of salmonella infection from reptiles”by the Health Protection Agency.
Salmonella are bacteria found in the gut of many animals, including reptiles. The bacteria can spread from the animals to cause illness in people. Though salmonella infection in people usually causes a mild illness with fever, vomiting, abdominal pain and diarrhoea, more severe illness can occur. Babies and young children are more likely to develop serious illness, which can be fatal.
People can also acquire salmonella infection from other sources including: eating and handling raw or undercooked meat, products containing raw egg or unwashed fruit and vegetables; drinking unpasteurised milk or milk products; or contact with infected animals, the droppings of infected animals, or contaminated soil.
How is salmonella passed from reptiles to people?
Most reptiles carry salmonella in their gut without showing any signs of infection and shed the bacteria in their droppings. These droppings can quickly spread over the reptile’s skin, and any surface or object that the reptile comes into contact with can be contaminated with salmonella, including cages, toys, clothes, furniture and household surfaces.
All reptiles should be presumed to carry salmonella in their gut, even if they do not show any signs of infection.
Salmonella can pass from reptiles to people when people put anything in their mouth that has come into contact with their reptile – particularly their fingers.
Some reptile foods such as frozen or defrosted mice, rats and chicks, can also contain salmonella and be a potential source of infection for both the reptile and its owners.
Hands can become contaminated when someone handles:
-
A reptile
-
Reptile cages or equipment
-
Raw reptile feed, including frozen or defrosted mice, rats and chicks
Food can become contaminated when it is:
-
Handled after someone has touched a reptile and not washed their hands
-
Put on surfaces that the reptiles have been in contact with
-
Shared with a reptile
Objects can become contaminated by contact with:
-
The reptile or its droppings
-
Contaminated hands or food
Who is most at risk of salmonella infection from reptiles?
Babies, children under five, pregnant women, the elderly and those with weaker immune systems are particularly at risk from infection.
Children are particularly at risk because they like to handle and stroke pet reptiles. As a result, their hands and fingers can become contaminated. Babies and small children may be infected by parents and other family members who have handled a reptile and then not washed their hands before feeding or touching the child.
They may also become infected from reptile droppings if the reptile is free to roam the home.
Good care of your reptile will reduce the risks of salmonella infection. It is not possible to eliminate salmonella from reptiles. Therefore antibiotic treatment of reptiles suspected to be carrying salmonella is not recommended. Below are some important guidelines on how to reduce the risk of catching salmonella from your reptile.
How can I reduce the risk of catching salmonella infection from my reptile?
- Always supervise children to ensure that they do not put your reptile, (or objects that the reptile has been in contact with) near their mouths, and wash their hands thoroughly with soap and water immediately after
-
Keep your reptile out of rooms where food is prepared and eaten, and limit the parts of the house where your reptile is allowed to roam freely
-
Always wash your hands thoroughly with soap and water immediately after handling your reptile, their cage or any other equipment such as soaking pools
-
Always wash your hands thoroughly with soap and water immediately after feeding your reptile, and after handling raw (frozen or defrosted) mice, rats or chicks. Ensure that all surfaces that have come into contact with defrosting food are cleaned thoroughly afterwards
-
Do not eat, drink or smoke while handling your reptile
-
Do not kiss your reptile
-
Do not use kitchen sinks to bathe your reptile or to wash their cage or equipment. If you use a bathroom sink or bathtub, it must be cleaned thoroughly with disinfectant afterwards
-
Dispose of waste water and droppings from your reptile down the toilet instead of a sink or bathtub
