The whale shark is the largest fish in the world, its size being up to 15 meters for 34 tonnes! However, most of the specimens encountered rarely exceed 12 meters. The whale sharks that we can see in Nosy Be are between 4 and 10m long, they are mainly juveniles.
They come to the tropical waters of Nosy Be to feed, on the surface, in the middle of shoals of bonito. Placid, calm and curious, these giants of the sea can easily be observed by swimmers and boats while respecting a specific code of conduct.
