Varanus salvadorii, known as the crocodile monitor, inhabits the lowland rainforests of New Guinea. It is one of the longest lizards, with powerful limbs, a prehensile tail, and sharp claws. This arboreal predator is noted for its agility and intelligence, preying on birds and small mammals.

Varanus salvadorii, commonly known as the Crocodile Monitor, is native to New Guinea. It is primarily found in the lowland and coastal regions of the island, both in Papua New Guinea and the Indonesian province of Papua (Western New Guinea).

This species inhabits tropical rainforest environments where the climate is hot and humid. The region experiences high rainfall, and the dense forest canopy provides ample cover and a diverse range of arboreal and terrestrial environments.

Varanus salvadorii is an arboreal predator, meaning it spends a significant amount of time in trees. It is well adapted to this niche with a long tail and claws suitable for climbing. Its diet mainly consists of birds, eggs, small mammals, and carrion, reflecting its role as both a scavenger and predator within its ecosystem.
