The Giant Bone Snakefish, also known as the Walrus Fish, Frigate Dragon, or Megalosaurus, is a species of fish in the order Osteoglossiformes of the order Orthopterygiformes, in the genus Megalosaurus. Like the elephant in its name, it is a huge freshwater fish, with adults reaching 2-6 meters in length and weighing up to 100 kilograms. With such a large body length, the Megalodon is naturally called a Megalosaurus.
