The Skull Island Rat is a common, dull-colored rat from the jungles of Skull Island. It is a common prey item for many predators.
Their ancestors were originally stowaways on the boats of the first humans to settle on Skull Island.
Predators include Megapede horridus, Megapede dereponecis, Megapede humus, howlers, moonspiders, and Calcarisaurus.
