About Common snake skink
What is the Common snake skink?
The Common snake skink, scientifically known as Riopa punctata, is a species of skink native to South and Southeast Asia. It is recognized by several common names, including the common dotted garden skink, punctate supple skink, and spotted supple skink. This lizard is found across a range that includes Bangladesh, India, Nepal, Pakistan, Vietnam, and Sri Lanka, often inhabiting hilly regions within these countries.
Physical Characteristics and Development
A notable characteristic of the Common snake skink is the distinct red tail observed in juvenile individuals. As the skink matures, this vibrant coloration fades and is replaced by small spots that can gradually merge to form continuous lines along the body. These spots may also be present on the head and extend to the snout. The body is covered in smooth, subequal scales, and the tail is typically slightly longer than the head and body. Adults display brown coloration on their upper surfaces, with each scale bearing a dark basal spot, while the underside is yellowish-white, sometimes with a black central dot on each scale.
Distribution and Habitat
The geographic distribution of Riopa punctata spans a significant portion of South and Southeast Asia. It is commonly found in various hilly terrains, with specific mentions in regions like the Yelagiris, Nilgiris, and Shevaroy Hills in India, as well as throughout other districts and countries within its range. The species' preference for these elevated areas shapes its ecological niche.
