Heliotrygon [Heliotrygon]
Description
Heliotrygon is a relatively recently described genus within the family Potamotrygonidae. It consists of large, freshwater stingrays known for their elongated, oval-shaped bodies and distinctive, rounded pectoral fin margins that extend forward beyond the head, giving them a somewhat sun-like appearance from above, which is reflected in their genus name. Native to the Amazon Basin, these rays are adapted to life in soft-bottomed river environments where they bury themselves in the sediment to ambush prey, primarily feeding on fish and crustaceans. They possess venomous tail spines for defense. Heliotrygon rays are notable for their secretive nature and relatively scarce occurrence, making them less known and studied than many of their relatives in the Potamotrygon genus.
