La Manta passa

Any of several genera of marine rays comprising the family Mobulidae. The Mobula Mantas I've seen in Burmesian waters last year, they come in groups of more than hundred Manats. Flattened, and wider than they are long, manta rays have fleshy enlarged pectoral fins that look like wings; extensions of these fins, looking like devils’ horns, project as the cephalic fins from the front of the head. Manta rays have short whiplike tails provided, in some species, with one or more stinging spines.
