| Articles

Whale sharks are the biggest fish of the ocean and the south of Ari Atoll, in the Maldives, is a great place to dive and snorkel with this breathtaking creature.

About whale sharks

Whale sharks are filter feeding sharks that can reach up to 12 meters in length and 20 tons in weight. Whale sharks live mainly in tropical and warm seas, and have been spotted all around the world. They are pelagic fish that can dive deeper than 1.000 meters.

Whale shark diet

As one of only three known filter feeding shark species, whale sharks feed mainly on plankton but there are also records of them eating schools of small fish, clouds of eggs, small squid and vertebrates.

Whale shark reproduction

Whale sharks are ovoviviparous, which means that the eggs remain in the body of the female sharks. The young sharks are born between 40 to 60 centimetres in length. Whale sharks reach sexual maturity at around 30 years old, and their lifespan is estimated to be between 70 and 100 years.

Whale sharks in the Maldives

The whale sharks that you can find in the Maldives are rather small ones, measuring on average between 4 and 8 meters. The best places to dive with them is the south of Ari Atoll, around Sun Island and Rangali.

Sun Island

The southern part of Sun Island’s reef is right on the Indian Ocean and it’s plateau is one of the best places to spot whale sharks. It’s depth ranges between 5 and 10 meters making it easy to spot these big fishes.


Rangali Island and its reefs offer a good chance to meet both mantas and whale sharks. It’s a great backup plan if you don’t find any in Sun Island.

Diving and snorkeling with the whale sharks


In the Maldives there is a admirable research program carried on by the Maldives Whale Shark Research Program to find out more about whale sharks. They identify the sharks by looking at their spot pattern which is unique to every individual, like a human fingerprint. Scientists agree the best ‘spot’ to identify a shark is just behind the gills.
