Hanifaru Bay, located in the Maldives, is renowned as a biodiversity hotspot and a sanctuary for marine life. During certain times of the year, massive groups of Manta Rays gather in a spectacular underwater ballet, feeding on plankton in a feeding frenzy. But what draws these gentle giants to Hanifaru Bay?

The Manta Rays gather in Hanifaru Bay primarily for one extraordinary reason - an abundance of plankton. Hanifaru Bay's unique underwater topography and ocean currents create the ideal conditions for a massive plankton bloom, especially during the monsoon season from May to November.

Plankton, which includes tiny organisms like krill and microscopic plants, serves as the primary food source for Manta Rays. As the bay's waters become nutrient-rich due to these natural factors, it triggers a remarkable feeding frenzy. Manta Rays congregate in large numbers to indulge in this seasonal buffet of plankton.

It's a catch-22 in Hanifaru Bay: the plankton needed to attract the Manta Rays also impacts visibility creating a unique challenge for snorkelers and underwater photographers. It also changes day to day - we were in the water with 50+ manta rays one day, and not one was to be found the very next day.

In recognition of its ecological importance, the Maldivian government and international conservation organisations have implemented strict regulations to safeguard this fragile ecosystem. Boat traffic in Hanifaru Bay is heavily restricted to minimise disturbances to the Manta Rays and other marine life. Only a limited number of licensed vessels are allowed to enter the bay each day, ensuring that human impact remains minimal. Only a certain number of snorkellers are permitted in the water at the same time, and they are only allowed to stay an hour. Scuba diving is not permitted in Hanifaru Bay.
