All About Blue Tree Monitors

Physical Characteristics

Blue Tree Monitors are medium-sized lizards, typically reaching lengths between 3 and 4 feet. They have slender bodies and long tails, which aid in their arboreal lifestyle. Their most striking feature is their beautiful blue scales, which can vary in shade from sky blue to turquoise. This vibrant coloration helps them blend into the lush green foliage of their natural habitat.

Habitat and Behavior

Captivity and Care

For those looking to keep Blue Tree Monitors as pets, it is essential to provide them with a suitable enclosure that mimics their natural habitat. A tall and spacious enclosure with plenty of branches and foliage for climbing is recommended. Temperature and humidity levels should also be closely monitored to meet the specific needs of these lizards.

Blue Tree Monitors: Characteristics and Behavior

One of the most distinctive features of the Blue Tree Monitor is its vibrant blue scales, which cover its entire body. These scales not only make this lizard aesthetically appealing but also serve a functional purpose. The blue coloration helps it blend in with the surrounding foliage, providing camouflage and protection from predators.

The Blue Tree Monitor is a relatively small species, with males typically reaching a total length of 3.5 to 4 feet and females slightly smaller. They have a slender body, long tail, and strong limbs equipped with sharp claws, allowing them to climb trees with ease. Their agility and ability to maneuver through branches make them perfectly adapted to an arboreal lifestyle.

Despite their small size, Blue Tree Monitors are active hunters. They primarily feed on a diet consisting of insects, small mammals, birds, and eggs. Their sharp teeth and powerful jaws enable them to catch and consume their prey efficiently. As opportunistic feeders, they will also scavenge for food if necessary.


Blue Tree Monitors are generally known for their docile temperament. They are shy and prefer to spend most of their time high up in the trees, away from potential threats. When feeling threatened, they use their strong tail and sharp claws as defense mechanisms. However, with proper handling and socialization from a young age, they can become more tolerant of human interaction.

Caring for Blue Tree Monitors: Tips and Guidelines

The Blue Tree Monitor is a reptile species native to the tropical rainforests of Australia. Known for its vibrant blue coloration and unique scale patterns, this lizard is a captivating addition to any reptile enthusiast’s collection. However, due to its specific care needs, it is crucial to understand the proper guidelines for caring for these beautiful creatures.

1. Enclosure: Create a spacious and well-ventilated enclosure for your Blue Tree Monitor. A tall and large terrarium with plenty of branches and climbing opportunities will mimic their natural tree-dwelling habitat. Ensure the enclosure has a secure lid to prevent escape.

2. Temperature and humidity: Blue Tree Monitors thrive in warm and humid conditions. Maintain a temperature gradient ranging from 85-95°F (29-35°C) during the day and a slight drop at night. Provide a basking spot with a heat lamp and use a reptile-specific thermostat to regulate the temperature. The humidity should be kept around 75-85% to replicate their tropical environment. Regular misting and the use of a humidity gauge is essential.

3. Lighting: Blue Tree Monitors require access to UVB lighting to properly metabolize calcium and maintain healthy bone growth. Use a UVB bulb specifically designed for reptiles and ensure it covers a sufficient portion of the enclosure. Provide a light cycle of 10-12 hours of light and 12-14 hours of darkness.

4. Diet: Blue Tree Monitors are carnivorous and primarily consume insects, small mammals, birds, and eggs. Offer a varied diet consisting of gut-loaded insects such as crickets, mealworms, and dubia roaches. Supplement their diet with small mice or rats once a week to provide essential nutrients. Ensure all prey items are appropriately sized to prevent choking hazards.

5. Hydration: Provide a shallow dish of clean, fresh water for your Blue Tree Monitor to drink from. Additionally, mist the enclosure daily to increase humidity and offer the opportunity for the lizard to drink droplets from leaves. Regularly clean and refill the water dish to prevent bacterial growth.
