The blue marlin is one of the open ocean's fastest, strongest predators and one of the most highly sought after game fishes everywhere that it lives. Reaching weights of at least 1800 pounds (~820 kg) and lengths of more than 16 feet (~5 m), the blue marlin is one of the largest species of bony fishes. Because blue marlin undergo such an amazing transformation in size (from being nearly microscopic to being one of the largest open ocean predators), they eat a wide variety of prey, throughout their lifetimes. At a young age, they eat tiny zooplankton, and their prey increases in size as they do. As adults, they eat fairly large bony fishes and squids. They are so-called blue-water fish, spending most of their lives far out at sea. The blue marlin is a highly migratory species, with individuals migrating across entire ocean basins and even between oceans. One individual, for example, was tagged off the east coast of the United States (western Atlantic Ocean) and recaptured in the Indian Ocean.
