Emerald Tree Monitor
The Emerald Tree monitor (Varanus prasinus), or the Green Tree monitor, is a small-to-medium-sized arboreal monitor lizard. It is known for its unusual coloration, which consists of shades from green to turquoise, topped with dark, transverse dorsal banding. This coloration helps camouflage it in its arboreal habitat. It also makes the Emerald Tree monitor highly coveted by private collectors and zoos alike.
Emerald tree monitors and their close relatives can be found in New Guinea, as well as several adjacent islands, on a few islands within the Torres Strait and in Cape York Peninsula in Queensland, Australia. The green tree monitor is reported to thrive in lowland environments including tropical evergreen forests, palm swamps and cocoa plantations.
The emerald tree monitor is about 30-39 in (75–100 cm) long with a slender body that helps it support itself on narrow branches. It also has a prehensile tail and long claws that it uses to grip branches. Unlike other varanids this monitor defends its tail rather than lashing with it for defense when threatened. The soles of the feet of the emerald tree monitor have enlarged scales which aid the lizard when climbing.
The emerald tree monitor's diet consists of large tree dwelling insects such as katydids, stick insects, cockroaches, beetles, centipedes, spiders, crabs, birds, and small mammals. Before swallowing stick insects, the lizards tear off the legs. Captive specimens tear off the limbs of rodents prior to eating them and as a result they are capable of swallowing mammals of a considerable size: A 135-gram (4.8 oz) lizard was documented as eating a 40-gram (1.4 oz) rodent, an animal almost one-third its size. Paleontologist and Biology Professor at Temple University, Michael Balsai has observed V. prasinus eating fruit(bananas) in captivity as has herpetologist and author, Robert G. Sprackland.
Clutches consist of up to five eggs, each weighing 10.5-11.5 grams (0.370-0.406 ounces) and measuring about 2.0x4.5 cm (0.79-1.8 in). As many as three clutches are laid throughout the year; captive clutches have been laid in January, March, April, November, and December. The female emerald tree monitor lays her eggs in arboreal termite nests. The eggs hatch between 160–190 days, typically from June to November after which the young eat the termites and the termite's eggs within minutes of hatching. Sexual maturity is reached in about two years.
