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.
Stingrays are common in coastal tropical and subtropical marine waters throughout the world. Some species, such as Dasyatis thetidis, are found in warmer temperate oceans, and others, such as Plesiobatis daviesi, are found in the deep ocean. The river stingrays, and a number of whiptail stingrays (such as the Niger stingray), are restricted to fresh water. Most myliobatoids are demersal (inhabiting the next-to-lowest zone in the water column); but some, such as the pelagic stingray and the eagle rays, are pelagic.
