What primary food sources constitute the diet of this benthic carnivore?
Answer
Invertebrates and small vertebrates in the sediment layer
As a classified benthic carnivore, the Xingu River Ray's feeding strategy revolves entirely around organisms living within or just above the riverbed sediment. Its diet typically includes a variety of small prey items such as small fish, aquatic worms, various crustaceans, and mollusks. The ray utilizes specialized electroreceptors located on its underside—a characteristic shared by all elasmobranchs but finely tuned for this freshwater application—to detect and locate these buried or hidden food sources within the murky substrate.
