For a while I've been struggling to identify this species, and haven't been able to find a satisfactory match, so I was hoping someone more versed in stingrays could lend a hand.
@Ebirah766 I have considered that species before as it is the right shape, but I can't find any atlantic stingray with a pattern close to this individual. The front is also a bit more pointier than what i see on images of H. sabinus.
