Mantarraya (Manta Ray)

Hi

Does anyone have serious info about this "fish"?
It's damn cheap here, about 0.28$ a pound, it's easy to cook, seems to have a lot of gelatin, seems to be low fat and have good protein. It's skin looks pretty gelatinous also, reminds me of a very soft pig skin

I just boiled it for about 20 minutes, it's a really soft white meat. The thing almost has no bones but some kind of cartillages that look like a bamboo stick wall. Right now I'm trying to dehydrate a little the whole thing up, I don't like it's sticky and gellatinous texture...maybe I'll upload a pic when it's done

I couldn't find any nutrition data relating to being used as a food source. My limited understanding of the above study seems to indicate a high pufa content. Maybe a more knowledgeable person will chime in.
