Manta rays

Manta rays swim in the ocean just beyond the reef. They can grow to 25ft wide and have the common name devilfish. This is not a good description as they are completely harmless with no sting like the stingray. They have no teeth as they feed on plankton which they collect as they filter water through their gills. They are easiest to see at night as plankton is attracted by light and the mantas follow to feed. We swam with these gentle giants just off the coast of Hawaii.
