A stingray weighing close to 900 pounds? This 6.6-ft.-wide giant stingray was caught, measured and released in Thailand this week, part of a National Geographic scientific expedition to search for giant fish. It may well be the largest known freshwater fish in the world.
University of Nevada biologist Zeb Hogan, a National Geographic Emerging Explorer, was pleased to discover healthy populations of giant stingray in Thailand, where once the fish were considered critically endangered.
Freshwater giant stingrays are among the largest of the approximately 200 species of rays. They are found in just a few rivers in Southeast Asia and northern Australia.
