Emerald Tree Skink

Appearance

The emerald tree skink is generally bright lime green in color, with large black eyes rimmed with yellow. However, their rear limbs or the lower half of their body may be medium brown with white speckling. In some cases, the entire body is brown or speckled with black. They are generally between 8.5-10" in total length.

Naming

It is known as 'kuka' in the Kotos Amarasi language of West Timor, Indonesia.

Distribution

It is found in arboreal forests of Taiwan, Palawan, Luzon and Sulu archipelagoes in the Philippines, New Guinea as well as the Indo-Australian archipelago and down south to the Solomon and Santa Cruz islands.

The emerald tree skink is frequently found in palm plantations in disturbed coastal areas.

Behavior

They prefer bare tree trunks without climbing plants. Several have even been sighted on minute islands with very little greenery, the record being four palm trees. It is a highly active species. Always on the move and is very squirmy if handled. They are an unaggressive species and sometimes observed to form little groups to gang up on bigger prey.

Reproduction

Courtship ritual is the same as most lizards. It as an oviparous species meaning it lays eggs rather than bear live young like most members of the skink family do. Eggs are usually laid in clusters of two. They can be easily bred in captivity and may live an average 7–12 years in captivity.

Food

It is mostly carnivorous, feeding on insects and other small creatures, although occasionally it may devour fruit and leafy plants. In some areas, it even steals dog food.

Evolution

Linkem, et al. found that the most divergent clades of "L. smaragdina" were in Sulawesi. Oceanic populations represent the most recent expansions. The origin of populations on most islands is attributed primarily to waif dispersals prior to human colonization, although human-aided dispersals cannot be ruled out for some populations.
