Adventure ocean – at the reef of manta rays

Manta rays or blanket fish are actually too big to be hunted. However just offshore from Mosambiks the animals gather in huge numbers – all of them with big bite marks. Where are these lesions coming from? A research team try to solve the puzzle. Based out of a local fishing village they collect information with the help of diving observations and underwater transmitters which are attached to the injured mantas. The research revealed something astonishing. A underwater thriller where the main acts are manta rays, whale sharks and tiger sharks.
