What critical function does the unique light-colored spot pattern serve?

Answer

Acts as an individual identifier, like a fingerprint

The mesmerizing pattern of light-colored spots and pale lines covering the whale shark's darker background skin is not random; it possesses high individual specificity. No two whale sharks share an identical pattern, making this unique configuration function exactly like a human fingerprint. Researchers utilize these distinct markings as a critical tool for tracking specific individuals across their extensive migratory routes throughout the tropical and warm temperate seas. Additionally, this patterning offers a degree of disruptive camouflage in the sun-dappled upper layers of the ocean.
