ABOUT THIS SPECIES

Varanus reisingeri, commonly called the Yellow Tree Monitor, is a small to medium-sized, arboreal monitor lizard endemic to the Misool Islands in Indonesia. Its bright yellow to golden coloration makes it one of the most visually striking tree monitors.

This species is diurnal and highly active, spending much of its time climbing and hunting insects and small vertebrates in the forest canopy. Its long limbs and prehensile tail make it agile and well-adapted to an arboreal lifestyle.

In captivity, Yellow Tree Monitors thrive in tall, enriched enclosures with climbing opportunities, hiding spots, and access to water. Maintaining proper temperatures, moderate humidity, and a varied carnivorous diet encourages natural behaviours, healthy growth, and overall wellbeing
