Ocean Sunfish | A GIANT Floating Heads from the Depths | Facts of the Largest Bony Fish

Ocean Sunfish, known as "mola mola", are the heaviest bony fish in the world. They can weigh up to 2 tons and grow up to 10 feet long. But besides being huge, they have been around for 45 million years. Because they don't have tails, they use their fins alone to slowly move across the ocean.
