How does *P. leopoldi* differ from the vast majority of stingrays regarding habitat?

Answer

It is a true freshwater specialist

A defining characteristic that separates the Xingu River Ray from the overwhelming majority of its relatives is its habitat requirement. While most stingrays are adapted to thrive in marine or brackish water environments, *P. leopoldi* is strictly a freshwater species. It makes its exclusive home within the Xingu River system, demonstrating a specialized evolutionary divergence away from its saltwater counterparts into the challenging, sediment-laden waters of the Amazon basin.
