This species feeds exclusively on the polyps of the tubular Acropora corals.
The Manta Ray is one of the most graceful creatures on earth. Huge but gentle filter feeders, Mantas glide ginormous distances across oceans, scooping up food along the way. They stop once in awhile to visit cleaning stations like the one you see here, where small fishes eat parasitic microorganisms off of the Manta’s body.
