River Stingrays [Plesiotrygon]

Description

Plesiotrygon is a genus of stingrays in the family Dasyatidae, commonly referred to as River Stingrays. These species are distinguished by their relatively small size, rounded disc-shaped bodies, and the absence of a distinct snout. Plesiotrygon stingrays are exclusively freshwater inhabitants, found in river systems of South America. They are adapted to a benthic lifestyle, often camouflaged against the riverbed where they hunt for invertebrates and small fish. The conservation status of these rays varies, with some species facing threats from habitat loss and pollution.
