The Blackedge Whipray (Himantura marginata) is a large (to 179 cm disc width), very poorly known stingray that is thought to occur off India, Sri Lanka, and Myanmar and possibly off Indonesia and Mozambique. Very little information is currently available on its habitat or biology. This species is presumably taken as bycatch in artisanal and industrial trawl and other net fisheries, but insufficient data are currently available to assess it beyond Data Deficient. Given its probable inshore occurrence in fished areas its conservation status will need to be reassessed once data are collected, particularly concerning catch levels.
