Monitor lizard Save The monitor lizards are large lizards in the genus Varanus. They are native to AfricaAsia and Oceaniabut are now found also in the Americas as an invasive species. A total of 79 species are currently recognized.
Some species are slow and docile, while others are notoriously aggressive. And some are lightweight, arboreal insectivores, such as the black tree monitor V. All in all, the family Varanidae is a diverse group of large, powerful lizards, none of which should be purchased on a whim or housed in under-sized environs.
Perhaps the most important part of getting involved with the monitor lizards is to intimately know the exact species that you are purchasing. Even though they are close kin to one another, different species of monitor can have very different needs in captivity; this may include diet, behavior, lighting, habitat size, relative humidity, and a host of other needs and conditions.
Black Tree Monitor The black tree monitor V. Adapted for a life in the forest canopy, this lizard has long, sharp claws, semi-adhesive pads in the center of its feet, and a semi-prehensile tail that aids it in the treetops by curling around branches and granting stabilization as the monitor moves from branch to branch.
As its name suggests, the black tree monitor is completely black at adulthood, but as a hatchling and sub-adult, this species wears a gray mantle speckled with yellow and cream-colored spots, freckles and ocelli.
The teeth of the black tree monitor are long, sharp and curve inward, allowing the animal to better hang on to prey in the canopy with reduced risk of dropping it to the forest floor below. Its diet in the wild includes all manner of invertebrates, rodents, birds, bird eggs, arboreal snakes and other lizard species.
While it will descend to the forest floor occasionally, this lizard prefers to hunt, bask and even sleep in the canopy. Although not as commonly kept as some other monitor species, the black tree monitor makes an excellent pet for the serious herp enthusiast.
Growing to a maximum length of less than 48 inches most adults seldom exceed 36 to 42 inches, the males being the larger of the two sexesthis small monitor species compared to others requires a very tall, elaborately furnished enclosure if it is to thrive in the captive environment.
I recommend either a custom-built enclosure of not less than 6 feet in height, 5 feet in width and 3 feet in depth, or a similarly sized, all-glass terrarium fitted with a secure, heavy-gauge screen lid. Furnish the enclosure with several stable climbing branches affixed to the enclosure walls by screws or bolted into a stable wooden base and plenty of living or artificial plants and vines to simulate the jungle canopy.
Flooring is of minimal concern, as black tree monitors rarely descend to the ground.
As is true with all monitor species, the more room you can provide your pet, the better. Large, screen-walled habitats with wooden framing and screen roofs to accommodate overhead lighting apparatus are the most cost-effective way to house a black tree monitor, but properly maintaining temperature and relative humidity in a screen-walled enclosure can be difficult.
Lighting should consist of at least eight hours daily of full-spectrum ultraviolet lighting. Many hobbyists build movable habitats and wheel them outside on sunny days so that the monitor may benefit from natural sunlight.
Another option is to have a separate, smaller habitat outside that is very securely built, where you can place your lizard during the day. Make sure it has a shady retreat, so that the monitor may escape the heat of the sun if necessary.
Never leave your monitor in the direct sun without a shady retreat, as any species of reptile can overheat and expire under such conditions. Although they are very manageable in size, black tree monitors can be nervous.
While most high-strung or threatened monitors will hiss, puff their throats and lash with their tails, the black tree monitor almost always tries to flee by rapidly ascending higher into the canopy.
Cornered or rudely handled specimens may also release their cloacal contents on their handlers. Then again, few monitor species are renowned for being comfortable with frequent handling.
In addition to such prey, the black tree monitor may be fed crickets, mealworms and virtually any other type of cultivated insect. Maintain daily ambient temperatures in the mids Fahrenheit, with a basking spot reaching into the high 90s to low s.
Nightly ambient temperature drops of 10 degrees or so in are acceptable. Maintain a relative humidity of 60 percent or higher at all times. Offer your black tree monitor water by securing one or more small, shallow dishes amid the climbing branches.
Misting the habitat with a spray bottle multiple times daily is also highly recommended. I also recommend placing a large, shallow pan of water on the floor of the enclosure, because even though they may not descend often, black tree monitors will emerge from the canopy to swim in pools and streams.
Like most monitors, V.
