What type of environment dictates the food sources for the Xingu River Ray?
Answer
Entirely within a freshwater context in the Xingu River system
The Xingu River Ray is strictly a freshwater species, confined to the Xingu River system, which is a tributary of the larger Amazon River. This geographical isolation inherently limits its food sources to organisms that naturally thrive in that specific, non-tidal freshwater environment. This contrasts with its marine relatives, whose diets might be more diverse due to broader habitat availability, making the ray's menu more dependent on local benthic invertebrates.
