The fifth limb
Did you know the Emerald Tree Monitor is one of the few Varanus species to actually use its tail as an extra limb? I thought it kind of obvious, but there I was wrong.
For the Varanus it is a nice treat after some 60 million years of evolutionary promotion. Btw. the tail is 2/3 of its total length. It uses its tail 100% in trees, prefering mangroves, rain forests, or even palm or cacao plantations.
The Emerald Tree monitor , 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.
