Emerald tree skinks are named for the bright green scales which cover the body of most individuals though some olive and black scales are also present.
They are native to South-east Asia where they are found in the treetops hunting for invertebrates.
This species is among the skinks which practice autonomy, the process of shedding their tail in an attempt to evade predators.
Their survival is threatened by birds of prey and snakes which will hunt them.
Read on to learn more about these riveting reptiles.
What does the Emerald Tree Skink look like?
The emerald tree skink is among the most brightly colored reptiles with bold green scales covering the majority of the body. These are broken up by a series of black scales which are mainly present around the base of the tail where they may form lines and blotches. The underside tends to be lighter in color.
While their coloration appears bold when displayed on a neutral background it is the perfect camouflage among the treetops of the forests they inhabit.
Their scales are smooth and shine in the light.
Their body is long and thin tapering to a point at both the end of the tail and snout.
Each foot ends with small, thin toes each of which sport a small claw to help them move through the trees in their habitat.
An average emerald tree skink will measure 18-25cm (7.2-10in) long. Males and females can be distinguished as the male has a yellow base on the rear foot which is not present in the females.
What does the Emerald Tree Skink eat?
Emerald tree skinks are carnivores which primarily feed on insects. They have also been recorded to eat small amounts of fruit opportunistically. Observations have been made of them taking dog food in urban areas.
