Basking shark

The world's largest fish, whale sharks can exceed 12 meters and 20 tonnes, inhabiting tropical and warm temperate oceans worldwide. Despite their massive size, they are harmless filter feeders, consuming plankton, fish eggs, and small fish by swimming open-mouthed through prey-dense water. They undertake vast seasonal migrations following plankton blooms. Endangered due to fishing, boat strikes, and the live fin trade, with population declining by approximately 50% over the past 75 years.
