These stunning images show a magical moment between an swimmer playing with manta rays at night. In her latest daring adventure, Alison Teal, 30, went free diving with the giant creatures off the coast of Hawaii, USA. Using only hand held dive lights, Alison dived 50 feet, being careful not to touch the mantas as they fed off the plankton in the light streams. Manta rays, who are harmless to humans, filter plankton from the water for their dinner. The special moment was captured by photographer Sarah Lee, while Mark Tipple filmed the adventure.
