A 1,200 km journey: Whale Shark migration confirmed

Researchers have documented a remarkable case: a young whale shark traveled 1,200 kilometers, swimming from the coast of Madagascar all the way to the Seychelles.

For a long time, scientists could only speculate that these marine giants were capable of such large-scale migrations. Now, it has been officially confirmed. Experts determined that the shark spotted near the Seychelles last year is the exact same individual first photographed in 2019 near Madagascar.

The "traveler" was identified thanks to a fascinating natural feature: the pattern of spots on a whale shark's skin is as unique as a human fingerprint. These distinct markings allowed experts to recognize the same individual with 100% accuracy several years later.

Despite their massive size—reaching up to 20 meters in length and weighing nearly 20 tons—these creatures feed exclusively on plankton and are completely harmless to humans. It is worth noting that in the Republic of Seychelles, whale shark hunting has been strictly restricted since 2003.

This discovery highlights the critical importance of international cooperation in protecting marine ecosystems. Detailed results of the study have been published in the scientific journal "Oryx" (The International Journal of Conservation).
