The lizard grows to 3 metres (10 feet) in total length and attains a weight of about 135 kg (about 300 pounds). It digs a burrow as deep as 9 metres and lays eggs that hatch in April or May. The newly hatched young, about 45 cm (18 inches) long, live in trees for several months. Adult Komodo dragons eat smaller members of their own species and sometimes even other adults. They can run swiftly and occasionally attack and kill human beings. Carrion, however, is their main diet item, although they commonly wait along game trails to ambush pigs, deer, and cattle. They seldom need to capture their prey directly since their septic bite quickly causes a lethal infection. Komodo dragons often find their prey in the process of dying or shortly after death.
