goanna - monitor lizard
Goanna D201 - These Australian large monitor lizards are savage carnivores, but they pose no threat to humans. Their diet consists of almost anything they can get their teeth into, and that means that other reptiles, including snakes, other lizards, and frogs, as well as birds and their eggs and chicks are on the goanna's menu. They frequently enter chicken coops and eat any eggs they find, but when living in a forested garden they are invaluable allies in the ongoing battle against insect pests. They rummage among the leaf litter and mulch on the soil's surface in search of beetles and other insects, and none stand even a fleeting chance of survival once a goanna is on their trail.
