Hello, Frank Indiviglio here. Turtles and other reptiles are full of surprises when it comes to reproduction. In the past few decades we’ve learned that incubation temperature, not genetics, determines the sex of many species, that some have dispensed entirely with males (i.e. the Brahminy Blind Snake) and that the massive Komodo Dragon is capable of reproducing without fertilization. Recently (May, 2011), biologists have determined that turtle embryos move within the egg and actively seek heat. This finding may cause us to re-examine conservation techniques, and raises an array of important questions – i.e., can turtle embryos actually determine what sex they will be? Read More »

Hello, Frank Indiviglio here. Asia’s freshwater turtles face an unprecedented extinction crisis, which may soon result in the loss of 90 or more species. In 2001, I joined other turtle enthusiasts in south Florida to help process nearly 10,000 turtles of many species that had been confiscated on route to food markets in China. The magnitude of the response to their plight heartened me, but today, unfortunately, we are still fighting an uphill battle. Please see Part 1 of this article for details. Following is a bit more on this sad situation. Read More »
Hello, Frank Indiviglio here. The term “Asian Turtle Crisis” was coined in 1997, when photos of thousands of rare turtles being slaughtered in a Guangzhou, China food market propelled the tragic plight of Asia’s freshwater turtles into the conservation spotlight. The private turtle-keeping and zoo communities were quick to take action, and a number of fine organizations and programs resulted. In 2001, I traveled to south Florida to help rehabilitate and place 7,500-10,000 turtles that had been confiscated in China.
Hard Work Pays Off
In south Florida I worked day and night alongside dedicated folks from the New York Turtle and Tortoise Society and other herp-oriented organizations, internationally-known turtle biologists, private turtle fanciers and zoo colleagues. The marathon effort was a grand success, with more turtles saved and placed in good homes than anyone would have dared hope upon first seeing their wretched condition. Given the passion, funds and other support that the situation aroused, the future looked promising. Unfortunately, 9 years later, the situation remains very bleak.
90+ Species Face Extinction
Recent studies by Conservation International (please see this article) reveal that at least 1/3 of the world’s 280 turtle species, including most of those found in Southeast Asia, are in imminent danger of extinction. Two photos on the homepage of the NY Turtle and Tortoise Society, taken 12 years apart in Guangzhou, China food markets, illustrate, graphically and tragically, that little has changed.
Several turtle species are represented by single populations numbering 12-50 individuals; only 4 specimens of the Red River Giant Softshell (Rafetus swinhoei, please see photo) are known to exist, the status of many Asian Box Turtles (Cuora spp., please see photo) can not even be determined, but several species have not been seen in years…the list goes on.
In Part 2 of this article we’ll take a look at the causes of the recent catastrophic declines in turtle populations and what is being done to reverse the trend.
Excellent article on the status of Asia’s turtles along with disturbing photos from food markets in China – READ THIS!
