 Blue Tree Monitor

The blue tree monitor is a species of monitor lizard only found on the island of Batanta, Indonesia. They were only discovered in 2001.

Zoo Diet

Our blue tree monitors are fed a variety of crickets, locust, small mice, quail eggs and cockroaches.

Wild Diet

Not much about their natural diet is known. However, other monitors eat stick insects, grasshoppers, crickets, moths, beetles, smaller lizards, small eggs and the occasional berry.


This species is diurnal and arboreal, thus it avoids predators by fleeing up a tree and keeping the trunk between itself and the intruder, as many anoles (and squirrels) do.
Their sharp claws give them a secure hold on almost any rough surface and they can climb with considerable ease. While moving amongst branches, they employ their prehensile tail as a grasping tool, in much the same way that chameleons use their tails. Unlike chameleons though, monitors may coil their tails horizontal to their bodies and rapidly uncoil it as a defensive whip.


If the female is receptive to mating, she will usually approach the male monitor. The two may spend time basking on the same perch over a period of days, or they may initiate mating immediately. During gestation, female blue tree monitors become more active, requiring more food. They also spend a considerable amount of time under the basking lamp, thus elevating their body temperature quite a bit.
After 3 to 5 weeks, eggs are laid and after an incubation time of 150 days they will hatch.


Blue tree monitors are listed as an Endangered species.
