About Morethia boulengeri
Morethia boulengeri: Boulenger's Skink
Morethia boulengeri, commonly known as Boulenger's skink, is a species of lizard belonging to the Scincidae family. This species is endemic to Australia and is notable for its adaptability, inhabiting a wide array of semi-arid and arid environments across the mainland.
Description and Identification
Boulenger's skink typically presents with grey or brown dorsal coloration, often adorned with darker flecks arranged in a longitudinal pattern. Its underside is predominantly white, distinguished by a thin white stripe running from the mouth to the groin, which is bordered above by a thicker black stripe. A key identifying feature, particularly in juveniles, is a distinctive red-orange tinge on the ventral side of the tail. Adult lizards can reach a total length of up to 10 cm, with an average snout-to-vent length ranging from 4.5 to 5 cm. The species also possesses unique square-shaped supraciliary scales above the eye region.
Habitat and Distribution
Morethia boulengeri is found across the majority of Australia, with its range encompassing at least part of every state and territory except for Tasmania. It thrives in diverse ecosystems such as dry sclerophyll forests, mallee, desert regions, scrublands, woodlands, and low shrublands. Its ability to inhabit environments with leaf litter and dead fallen vegetation contributes to its success as a generalist species. In some areas, such as the Murray catchment, population densities can be remarkably high, reaching several hundred individuals per hectare.
Diet and Reproduction
As an insectivorous species, Boulenger's skink primarily feeds on arthropods and snails. Moths constitute a significant portion of its diet, supplemented by other insects like spiders, beetles, ants, and cockroaches, all of which are abundant in its preferred habitats. Reproduction occurs during the warmer months of spring and summer. During this period, males develop a vibrant orange throat, signaling fertility. The species is oviparous, with females laying an average of three eggs per clutch, typically producing around three clutches annually. The incubation period for these clutches lasts approximately 60 days, during which there is a notable increase in oxygen consumption.
Naming
The specific name, boulengeri, and several of its common names, such as Boulenger's skink, honor George Albert Boulenger, a Belgian-born British herpetologist recognized for describing numerous reptile, amphibian, and fish species.
