How does a Manta ray catch its food?

Manta rays are filter feeders and bottom feeders. They will strain fish larvae, plankton, and mollusks from water passing through their mouth and out of their gills. Individuals will sometimes perform barrel rolls for hours on end. In the Maldives (islands), hundreds of mantas will congregate and make a feeding vortex, known as cyclone feeding. They swim around in a circle in tight formation, literally casuing a cyclone in the water. This concentrates the plankton that they are feeding upon.
