Overview

Whale sharks are the largest fish in the world – they are easily distinguished from other sharks by their massive size, reaching up to 40 feet in length, and their distinctive pattern of light spots and stripes on a grayish-blue background. Their wide, flattened heads, enormous mouths, and five prominent gill slits are also unique features.

Migratory Patterns

Whale sharks exhibit seasonal migration patterns. They typically start in tropical coastal areas near the equator, such as the Philippines, Mexico, and Australia, during spring and summer months. As water temperatures change, they move towards cooler waters, often traveling to areas off the coasts of Japan, South Africa, and the Galapagos Islands. Some populations have been observed migrating between the Gulf of Mexico and the Caribbean Sea. Long-distance migrations have been recorded, with individuals traveling over 20,000 kilometers across ocean basins.
