Why are whale sharks attracted to the Mexican sea?

Whale sharks are attracted to the Mexican sea, particularly the waters off Isla Holbox and the Yucatán Peninsula, due to the seasonal abundance of their primary food source—plankton. The warm, nutrient-rich waters provide ideal conditions for these tiny organisms to thrive, especially during the summer months when upwelling occurs. Additionally, the area's geography and ocean currents create a favorable environment for feeding, drawing these gentle giants to the region.
