Manta rays now have government protection from the threat of fishing within the archipelago's vast ocean.

Fishermen can make up to $500 for each ray caught. But studies suggest a single animal could generate up to $1 million in tourist revenue.

The government's decision has been welcomed by conservationists. Manta rays are listed as vulnerable by the International Union for the Conservation of Nature.
