Varanus prasinus, commonly known as the Emerald Tree Monitor, is native to New Guinea and nearby islands. This arboreal species is distinguished by its vibrant green coloration, prehensile tail, and sharp claws, which aid in climbing. It primarily feeds on insects and small animals and is known for its agility and intelligence.

Varanus prasinus, commonly known as the Emerald Tree Monitor, is native to the tropical forests of northern New Guinea and several adjacent islands, including the Aru Islands, the Schouten Islands, and the Louisiade Archipelago.

The Emerald Tree Monitor inhabits humid, tropical rainforest environments where the climate is consistently warm and wet. These areas typically experience high humidity levels and substantial annual rainfall, creating lush and dense vegetation.

Varanus prasinus is highly arboreal, spending most of its life in the forest canopy. Its ecological niche includes hunting for insects, small mammals, and birds among the trees. The species is well adapted to life in the trees with long limbs and a prehensile tail that aids in climbing and maneuvering through the branches.
