What does the ray's specific designation to the Xingu River basin often imply about its population?
Answer
A high degree of endemism or a well-studied population originating there
When a specific species name, like the Xingu River Ray, is tied so closely to a single river system, it generally suggests a significant level of habitat specialization. This specialization often manifests as a high degree of endemism, meaning the species is unique to that specific geographical area and not found naturally elsewhere. Even if the general *Potamotrygon* genus is widespread, this specificity implies evolutionary isolation or that this particular location is the best-documented source population.
