Whale sharks live in warm, tropical oceans around the world, including areas off Mexico, Australia, and the Philippines. They are the largest shark species, able to grow over 12 meters long. Whale sharks feed on plankton, jellyfish, and small fish. Females can carry up to 300 eggs at a time and give birth to pups about 2 feet in length. Despite their massive size, whale sharks are generally harmless to humans.
