Manta Rays Swim With Divers

Manta rays are some of the largest fish in the sea, the biggest ever caught measured 7.6 metres (25 ft) across, and weighed of about 5,100 lb. Their top swimming speed is around seven miles an hour and, despite their huge size, mantas only feed on tiny plants and animals known as plankton filtered from the water passing through their gills as they swim.
