February 24, 2009--Fishers and scientists announced this week the catch, and release, of what is likely the world's largest known freshwater giant stingray.
The giant stingray, weighing an estimated 550 to 990 pounds (250 to 450 kilograms) was reeled in on January 28, 2009, as part of a National Geographic expedition in Thailand.
The stringray's body measured 6.6 feet (2 meters) wide by 6.9 feet (2.1) meters long. The tail was missing. If it had been there, the ray's total length would have been between 14.8 and 16.4 feet (4.5 and 5 meters), estimated University of Nevada Biologist Zeb Hogan.
Hogan was in Thailand searching for giant fish as part of the Megafishes Project—an effort to document Earth's 20 or so freshwater giants.
The new find gives Hogan hope that the giant stingray, once overfished, may be more abundant than previously thought. And it may confirm the giant stingray as the heavyweight champ of the Megafishes Project.
