Hanifaru Bay, one of the World’s top feeding Hotspots for Mantas

Hanifaru Bay is located at the south east edge of Baa Atoll, north Maldives. Covering 1,200km² – barely the size of a football field, the small area is known to be one of the world’s top feeding hotspots for manta rays and one of the Maldives largest concentration of whale sharks.

Since 2011, Baa Atoll has been listed as a Unesco World Heritage Site as it is home to one of the largest concentration of corals in the Indian Ocean and to an incredible biodiversity.

During the summer monsoon, visitors can swim and snorkel with these extraordinary creatures.

There are other places in the world where Mantas gather to feed but Hanifaru Bay is the only place where they, together with whale sharks aggregate in such unusually high numbers.

There are up to 200 manta rays who congregate in the bay.

Swimming with manta rays in Hanifaru Bay, a magical experience

Swimming with manta rays and/or whale sharks is a dream for sea lovers. If this is on your bucket list, then Hanifaru is The Place to be.

It is common to see dozens of manta rays swimming around to feed on planktons as the reefs in the bay becomes a cleaning station (both species get a regular hygiene check by parasitic copepods and a variety of small cleaner fishes) during the Maldivian winter monsoon.

However, this is not a rarity in the Maldives. There are many other cleaning stations in several atolls such as Ari, Rasdhoo, North Male, Laamu…

Hanifaru has another asset and a major one : the currents acting at this time of the year push their favourite food, the plankton, towards the bay, which, due to its shape, keeps it inside.

This mass of food is an opportunity for the two species to offer each other pantagruelic meals for several months.

This is the ideal time to observe them closely, as they stay in the bay in large numbers.

Swimming with them is magical. Manta rays, like whale sharks, are very curious about humans and often approach them gracefully and peacefully.

It is NOT allowed to TOUCH, RIDE or SWIM AFTER any creature

and KEEP your distances.

Why is it so populated with Mantas and Whale Sharks ? The details.

Because the area is full of phytoplankton and has tons of their favorite meal, the zooplankton. And it even gets better : both foods get trapped in the bay !

Beside this feast for the filters, Hanifaru is also one of the very few places in the world where whale sharks congregate to mate.

Why is it so full of plankton ?

Because the bay has a unique shape and specific currents.

The perfect cocktail to concentrate planktonic food which is called Plankton Soup.

Explanation of Hanifaru phenomenon

Winter Monsoon currents ( monsoonal currents on the map ) bring the plankton swarms towards the east of the atoll, a massive amount goes right inside the bay, and gets trapped due to its shape ( closed at the estern edge ).

About Plankton soup…

Hanifaru is a real feast for plankton feeders. It offers both of them, phytoplanktons which are plants and zooplanktons which are animals.

The area is unique as it has a vigorous water circulation system due to the funnel-like reef shape – approximately 1,300m long and 600m wide. During the north-western monsoon (May / June to November), enormous quantities of plankton ( phyto and zoo get trapped in the bay, creating what is known as plankton ‘soup’, which attracts large numbers of Mantas and other filter feeding large creatures such as whale sharks who have no teeth.

Phytoplankton VS Zooplankton

Interesting fact : zooplankton feed on phytoplankton.


Phytoplankton. © NOAA

Phytoplankton are microscopic plants, which play a huge role in the marine food web. Like plants on land, phytoplankton perform photosynthesis to convert the sun’s rays into energy to support them, and they take in carbon dioxide and produce oxygen.

Because they need the sun’s energy, phytoplankton are found near the water’s surface.


Zooplankton. © NOAA

Zooplankton include microscopic animals (krill, sea snails, pelagic worms, etc.). During the daylight hours, zooplankton generally drift in deeper waters to avoid predators. But at night, these microscopic creatures venture up to the surface to feed on…phytoplankton. This process is considered the largest migration on Earth; so many animals make this journey that it can be observed from space.

Scientific Studies about the high presence of Plankton in Hanifaru

During the summer period, plankton, normally located at a depth, rises to the surface with currents. Manta rays feed when zooplankton biomass is high, which is typically observed on the high to ebbing tide at Hanifaru Bay. Oceanographic investigations in Hanifaru suggest tidal currents draw zooplankton into the shallow reef systems of the atoll, where they become trapped inside due to a back-eddy mechanism created by the combination of the unique shape of the reef system and the currents.

When is the best time to snorkel in the sanctuary ?

The best time to visit and snorkel in Hanifaru Bay is between the months of May and November when the currents bring plankton and krill. It’s also a peak for whale shark mating.

The peak season, with the highest concentration of planktons and individuals really starts from July until September.

your experience in Hanifaru is limited to 45 minutes in the water as per local regulation.

About Manta Rays

© Finolhu Maldives

Reef manta rays, ( – scientific name Mobula Alfredi ) , are part of the Myliobatidae family, which includes most marine rays. Mobulas alfredi are also commonly known as “flying giants” because they do not swim on the sea bottom like the eagle ray for example, but rather in suspension between the bottom and the surface.

In addition, their beautiful fins look like wings. Manta rays gracefully move between a depth of 0 to 1000 m as if they were flying with wings.

Mantas are as spectacular as they are peaceful. With a wingspan that can reach an impressive 8.8 m, they can weigh up to 2.5 tons, as much as a medium sized 4X4 truck.

They congregate in a few places on the planet to feed on microscopic plankton, the most famous of which are Peru, Mexico, Hawaii and the Galapagos and of course Hanifaru Bay which is the most spectacular of all.

Mantas have long been known by Maldivians, who used to hunt them for their skins to make Bodu Beru, the traditional Maldivian drum. This is no longer done.

Fisheries also target manta rays for their branchial filter plates and cartilage for the Chinese market who use them in traditional medicine and food.

This is now fortunately forbidden in Maldives ( read further for more details on their protection ).

Hanifaru is also the Maldives second most important whale shark aggregation after South Ari Atoll.

About Whale Sharks

Whale sharks are the largest known fish specie and can weigh up to over 30 tonnes.

They are by far the largest living nonmammalian vertebrate and sole member of the genus Rhincodon and the only extant member of the family.

Whale sharks are highly migratory species and difficult to follow. However, thanks to the development of ecotourism activities around the world, their biology, distribution and movements are now more studied in various places on the planet. The Maldives are one of the most important of all.

Whale sharks are closely monitored and studied by a great local organization : The Maldives Whale Shark Research Programme (MWSRP).

Before being protected ( in the Maldives and a few other countries ) , they were also hunted for their skin and liver for the same purposes as Mantas.

From an overcrowded place to A UNESCO International Heritage since 2011

In the early 1990’s dive safari boats began to visit Hanifaru Bay but soon the extraordinary area became overcrowded with boats, divers and snorkelers every day. The balance and harmony of Mantas and Whale Sharks got threatened.

In 2009, the Maldivian government finally declared Hanifaru Bay a Marine Protected Area and in 2011 it became a UNESCO International Heritage Site, which means that fishing, shipping and swimming are restricted in the area.

A maximum of 5 boats and no more than 80 people per day and at any given time is allowed.

A Pledge for protection from the neighboring resorts

The Maldives generate an estimated 8.1 million USD annually in direct revenue for manta ray tourism alone.

Resorts which are located close to Hanifaru Bay surely benefit from a prime location which attracts many visitors, but having such a wonderful and fragile area at their doorsteps is a great responsibility.

Several resorts made a pledge to protect and preserve Hanifaru and its creatures by establishing a Memorandum of Understanding (MoU) which lays out the agreed guidelines for everyone to adhere to when visiting Hanifaru Bay.

One of them is to ensure that there is always an in-water supervisor with a ratio of at least 1 guide for a maximum of 8 guests.
