You will not find one perched beside Danerys Targaryen or on the roof at Hogwart’s School of Witchcraft and Wizardry. Prince Charming does not slay one, and Hiccup the Viking will not teach you how to train one. Yet the Sailfin dragon is more than just literature and legend.
The Sailfin dragon is real – and in danger.

The Sailfin lizard, commonly known as the Sailfin dragon, is one the most secretive species on the planet and also one of the hottest commodities in illegal pet trading. In fact, until recently, scientists were unaware of the Sailfin’s existence entirely. But thanks to thirty years of research, the endangerment of this magnificent species may soon draw to an end.
In collaboration with Rafe Brown and Andres Lira from the University of Kansas, in addition to the Philippine National Museum and the Biodiversity Management Bureau, Sam Noble Museum herpetology curator Cameron Siler has spent the past ten years studying these elusive creatures in hopes of answering two questions.
1. Where is genetic diversity distributed for this species?
2. How can this knowledge be applied to the illegal pet trade?
To answer these questions, herpetologists conducted 40,000-50,000 biological surveys across 7,100 islands in the Philippines. What’s a biological survey, you ask? Essentially, researchers conduct surveys in rainforests to document all species present at a site. Then, they collect vouchered specimens and tissue samples that represent each species in global natural history collections. Genetic samples are used to develop a DNA database that allows herpetologist to construct phylogenies, or family trees, that illustrate relationships between species.

“It’s always a great feeling to have an example of an applied conservation approach to what we do in a natural history museum,” said Siler. “We stockpile the world’s biodiversity, yet a lot of people don’t know why we do it or what it gets used for.”
But how does this keep Sailfins off the black market?
To establish sustainable homes for the Sailfins, scientists must first understand what types of habitats these lizards prefer. Then, by cataloguing the locations of all vouchered individuals (museum specimens), researchers can check to see what proportion of Sailfin habitats are government protected – and that’s exactly what the team did.
But according to Siler, the findings were “astonishing”.
Although the Sailfin lizards are considered a vulnerable species, less than 10 percent of their suitable habitat is currently being protected. But that’s not all. Every single specimen surveyed at one of the major Filipino pet markets came from peninsula in northeastern Philippines. Yet only 0.8 percent of this land is protected.
All specimens from local pet markets stemmed from just one peninsula
According to Siler, these findings are terrifying but promising. If illegal pet trade specimens are being collected from one isolated region, enforcement of local conservation laws will be more controllable.
“Knowing this, there actually can be more of a directed conservation effort in this region,” Siler said. “That’s an exciting result of combining DNA studies with vouchered biodiversity collections in natural history museums.”
Siler, Brown and their collaborative team plan to continue their research in July 2014, thanks to a RAPID grant from the National Science Foundation. This expedited grant allows the researchers to continue collecting biological surveys in the wake of Typhoon Haiyan, which devastated much of the Philippines in 2013.
So, what does this mean for the Sailfins?
The more herpetologists understand about this rare species, the more local governments can implement effective conservation regulation. Although the story of the Sailfin dragon is not yet concluded, researchers are looking forward to a new chapter – a chapter of knowledge, a chapter of change.

Doctors complete the first successful blood transfusion in Brussels, and World War I begins. When looking back on this most historic year, one critical event is often overlooked– the extinction of the Passenger Pigeon.
The Passenger Pigeon in 1898
With a population between 3 and 5 billion birds, the Passenger Pigeon was once the most abundant bird in North America, and possibly even the world. Written accounts describe how flocks would darken the sky for hours and days, and how the beating wings sent a chilling draft down from the sky. However, in just a few decades, the species became extinct.

Human exploitation, namely hunting and commerce, destroyed nearly every major nesting area over the course of 40 years. No one documented a successful mass nesting during this time, which had in the past contributed greatly to the survival of the species. This bird occurred only in North America and was no stranger to the Sooner State.
Prior to the twentieth century, the Passenger Pigeon often frequented eastern Oklahoma during winter. It is even possible that a handful of lesser-known Oklahoma landmarks were named after this species: Pigeon School (Cherokee County), Pigeon Roost Church (Choctaw and Seminole counties), Pigeon Creek (Latimer and Le Flore counties) and Pigeon Mountain (Le Flore County).

Unfortunately, the story of the Passenger Pigeon is not the only tale of exploitation and extinction. Now, The Chicago Academy of Sciences and its Peggy Notebaert Nature Museum are using this tragedy as a cautionary tale through a notable conservation initiative, Project Passenger Pigeon.
According to the project website, the international campaign seeks to promote awareness about the Passenger Pigeon and other endangered species while encouraging people to take action against human-caused extinction. Ultimately, the project is about fostering biodiversity by prompting people to question their role in the larger ecological community.
As a strong advocate of wildlife conversation, The Sam Noble Museum commends the work being done by Project Passenger Pigeon and other similar efforts. From Sept. 13 to Jan. 18, the Sam Noble Museum will showcase portraits of engendered and extinct species, including the Passenger Pigeon, as part of the exhibit Rare.

If Project Passenger Pigeon has inspired you to get involved, there are several environmental advocacy groups to join: The Nature Conservancy, World Wildlife Fund, Natural Resources Defense Council, The Sierra Club, Conservation International and Wildlife Conservation Society, to name a few. Of course, joining an organization isn’t the only way to support conservation efforts.
"You could become informed about conservation issues, volunteer in community environmental projects or become a citizen scientist,” suggests Janet Braun, staff curator. “You could also join or donate to a museum or conservation organization while living and promoting a conservation lifestyle.”
Scientists estimate that there are over 8.7 million species of living organisms on Earth at this time. Biodiversity is a precious thing that must be protected, as the tale of the Passenger Pigeon reminds us. They say that history always repeats itself - but by promoting the conservation of species and habitat, perhaps we can build a better tomorrow from yesterday’s mistakes.
