Even though these huge fish are 12 feet across, the social behavior of the reef manta ray has generally remained secretive--until now. In rare drone footage captured off the coast of Oahu in Hawaii by Mark Merkley, the unique and graceful feeding behavior of the reef manta ray is captured in great detail. Manta ray individuals "stack" behind one another while feeding. The social groupings of manta rays are intriguing in part because they aren't necessarily family groups.
