Approximately what diameter can adult Xingu River Rays reach?
Answer
About 50 centimeters
The typical size attained by mature Xingu River Rays is relatively modest compared to some other ray species. Documented adults commonly reach diameters approximating 50 centimeters. While the text notes that larger specimens have occasionally been observed, the 50-centimeter measurement serves as the standard benchmark for the adult size of this species that lives pressed against the river floor.
