Stingray Giant Freshwater. Stingray, Giant Freshwater (Himantura Chaophraya) The Giant Freshwater Stingray in Thailand is believed to be the largest freshwater fish on the planet reaching weights approaching 1000 lbs.
Giant freshwater stingrays are listed as endangered by the International Union for the Conservation of Nature, in part due to Hogan's and Nantarika's work. âThese rays are decreasing rapidly since there is no national law to protect them,â Nantarika says.he giant freshwater stingray has the longest spine of any species of ray, up to 15 inches, and carries powerful venom. The animal uses its spine for defense and it can be lethal, but injuries to people are quite rare. Check out this archive video of Zeb Hogan examining another freshwater stingray.
