cliff and snapping a sailor in two. Ligocristus – A hadrosaur that is fed upon by a Foetodon. They resemble Saurolophus a hadrosaur from the Cretaceous. Megaprimatus Kong - A huge species of Gorilla, they were the largest primates to have ever lived, even bigger than Gigantopithecus, the previous record holder. The average M. Kong could stand up to 6–8 meters (18–25 feet tall) and possibly weighed 6 tons. By 1933, there was only one of them left. This specimen, an old male, was captured and brought back to New York City by Carl Denham, but escaped and was shot down off the top of the Empire State Building, rendering the species of Megaprimatus kong extinct. Moonspider - Not a true spider (it is really a member of the Solifugae), the Moonspider is a nocturnal creature that lives in the Lowlands. It appeared briefly in the film when Ann Darrow made her escape from King Kong. Piranhadon titanus – Only appearing in The World of Kong and more prominently in the extended cut, Piranhadon is a fish. In the extended cut, a Piranhadon attacked the rescue team led by Hayes, Carl Denham and Jack Driscoll, killing three sailors and very nearly swallowing Driscoll whole. Piranhadon has poor vision, only being able to discern prey's silhouettes, using the barbels on its chin to sense vibrations and the light from the surface to detect passing prey. Terapusmordax obscenus – A giant bat-like rodent. A swarm of them appear in the film roosting in Kong's lair. When Jack Driscoll attempts to save Ann, he awakens Kong. The Terapusmordax then attack Kong; he fends them off while Jack and Ann escape by climbing down a vine. When one of the Terapusmordax attempts to kill Jack and Ann, Jack grabs the wing and the Terapusmordax lowers them down. They then fall into the river below. They also appear in the associated video-game where they gain juvenile-forms and a bluish, airplane-sized species. Terapusmordax evolved from hairless rodents that developed wings. They measure about in body length and in wingspan. Vastatosaurus rex – A descendant of Tyrannosaurus, but much bigger with three fingers unlike it's ancestors during the Cretaceous. It appears in the film in a scene where three of them fight Kong. Vastatosaurus are the top apex predator of Skull Island. They can grow up to long. Juveniles hunt separately from the adults in the jungle,
