Yep, its one of the largest reef manta aggregations in the world. I've never been, you're very lucky!

I thought the way to tell between devil and manta rays was that devil rays had straight/pointed parts(protrusions? not sure what to call them) on their faces and manta rays had ones that curved in. is this not as reliable as looking at their mouths?

In both manta and devil rays, the lobes can be furled or unfurled at will. Here's a true giant manta furled and unfurled. Furled is for straight cruising, unfurled for feeding and maneuvering.

PS asked me about cephalic lobes could be used to tell devil and manta rays apart, with the devils' pointing forwards and the mantas' curving down and under. Short answer is no, because...

And here's a giant manta with lobes furled for straight cruising. Its probably true that devil rays spend more time with theirs furled, but both animals can be either furled or unfurled at will, so its not a reliable character

Ah, good question, but it's a common misconception. The "horns" (cephalic lobes) can curl up to point straight ahead (cruising position) or unfurl to use for feeding or tight maneuvering. Here's some Mobula feeding with lobes unfurled

Anyone fancy collaborating with me on my (our) next article? I’m interested in what microbes people have been able to culture from any coral, any location (published or not published - it does not matter). Please RT to reach maximum coverage.

Stop what you're doing and watch this video! The early morning group behaviour is just so spooky beautiful. A tiny vignette into the life of one of the oceans largest and most mysterious animals.

Great little thread about manta/mobula taxonomy. Definitely worth your time to read. It starts here:

Giant devil rays are also really cool and underrated, they’re probably my favorite Mobula ray! They’re endangered, they have a little raccoon mask, and even the name Mobula mobular is kind of cute and endearing imo. Anyone who likes mantas should look them up!!
