Also try to get the photo when their pelvic fins are spread apartIt’s too blurry for me to tell, male stingrays have two claspers underneath the base of their tail. If you can get better photos of their bellies near the base of their tail, I could tell you which is M/F
When they’re newborns the claspers are tiny, they can be hard to spot unless you pull them out with a clear container and look from underneath. Sometimes when the pelvic fins are closed, the skin sort of folds up a bit and can hide the newborns claspersReese11 How small are the claspers on new born/young rays?
