The ostrich lays the largest eggs on land but, the whale shark lays the largest eggs IN THE WORLD.
An egg from a whale shark measuring 14 inches in diameter was found in the Gulf of Mexico in 1953.
Those giant whale shark eggs grow up to be really big sharks. Whale sharks are the largest sharks in the world, and therefore the largest fish in the world too. The largest whale shark ever found was 40 feet, 7 inches.
