Hi! These are Atlantic pygmy devil rays (Mobula hypostoma) -- cool footage of them probably feeding in the surf! I know a PhD student who is studying these rays with Mote Marine Laboratory to support their conservation. Do you remember the date that you took the video, or at least the month and year? As well as if there was a nearby landmark for a more precise location? Pygmy devil rays are endangered and very understudied so any information you’re able to share would be helpful in understanding the seasonality and distribution of this species! Thanks for your time, we appreciate it =)
