ABOUT THIS SPECIES

Varanus jobiensis, commonly called the Peach-throat Monitor, is a medium-sized, semi-arboreal monitor lizard native to Papua New Guinea. Its name comes from the distinctive peach to pinkish coloration often visible on the throat, contrasting with a darker green to brown body.

This diurnal species is agile and active, spending much of its time navigating trees and shrubs while hunting insects and small vertebrates. Its prehensile tail and long limbs make it an adept climber, while its alert behaviour aids in foraging and predator awareness.

In captivity, Peach-throat Monitors thrive in tall, enriched enclosures with climbing opportunities, hides, and access to water. Providing proper temperature, moderate humidity, and a varied carnivorous diet encourages natural behaviours, healthy growth, and overall wellbeing.
