The Komodo dragon's diet includes invertebrates, other reptiles (including smaller Komodo dragons), birds, bird eggs, small mammals, monkeys, wild boars, goats, deer, horses, and water buffalo. Young Komodo dragons will eat insects, eggs, geckoes, and small mammals. Komodo dragons may eat people and, they can even dig up bodies from their graves to eat them. Therefore, people on Komodo Island moved their graves from sandy to clay ground and piled rocks on top to stop the lizards from digging up dead bodies.
