Whale sharks are the largest fish in the sea. They can grow more than 40 feet in length, weigh up to 47,000 lbs, and have a lifespan of about 70 years. They can be found cruising in the open waters of tropical oceans. But despite being enormous, whale sharks are no threat to humans. The docile beasts, which feed almost exclusively on plankton, have often been referred to as “gentle giants.”
