[edit] Physical Description

Hatchlings and juveniles are a dark grey in colour, with regular rows of bright yellow-green dots which are particularly noticeable on the back. As they achieve adulthood they turn completely black, losing the colourful dots. Fully grown specimens reach 3 to 4 feet in length, with the males slightly larger than the females.

[edit] Unique Characteristics

The Black Tree Monitor is generally well adapted for living in trees. Its tail is particularly long, sometimes two-thirds of the overall body length, and is used in a prehensile manner to stabilize the animal in the branches. In fact, the tail is used solely for this purpose, as the animal does not evince the defensive tail-lashing behaviour seen in other monitor species. The Black Tree Monitor’s feet sport large claws and adhesive soles, which help it to maintain grip in the trees. It also has unusually long teeth for a monitor of its size, which may help it to hold on to prey it catches in the canopy.

[edit] Food Web

Black Tree Monitors are carnivorous, taking a range of prey items. Mostly commonly eaten are insects, smaller lizards, and small mammals such as shrews. They may also take scorpions, eggs, and nestlings. They are themselves predated by larger lizards and snakes. Foxes, which were introduced to the region, are an unnatural predator of the Black Tree Monitor. They are also hunted by humans.

[edit] Geographical Distribution and Habitat

The species is native to the forest of the Aru Islands of Papua New Guinea, where it is known locally as Waweyaro.

[edit] Conservation

Varanus beccarii is not currently on the IUCN red list. However considering its restricted range, it is vulnerable to any loss of habitat in the region. It is also popular in the pet trade, with most specimens being wild-caught because they need so much room to breed in captivity. This means that almost no one breeds them, except for some zoos and very few private breeders.
