About Chalcides striatus
The Western Three-toed Skink
The western three-toed skink, scientifically known as Chalcides striatus, is a distinctive lizard species native to southwestern Europe. Its range encompasses the Iberian Peninsula (Spain and Portugal), southern France, and the northwestern Italian region of Liguria. This reptile is characterized by its serpentine appearance, a result of its extremely small, underdeveloped limbs, each bearing three toes. Despite these tiny appendages, it can move surprisingly fast by undulating its body.
Physical Characteristics and Habitat
Adult western three-toed skinks typically reach lengths of up to 43 cm (17 inches). Their bodies are covered in smooth, glossy scales, often exhibiting a silvery or bronze sheen. A prominent feature is the presence of approximately ten slender, longitudinal dark lines that run the length of the body, with the head usually being darker than the rest of the body. They are distinguished from similar species, like the Italian three-toed skink, by their slightly larger limbs and the equal length of the three toes on their hind feet.
These lizards favor damp yet sunny environments with dense, low-lying vegetation. Their preferred habitats include meadows, grassy slopes, stream verges, marshes, hedges, and even arable land and rural gardens. In areas closer to the Atlantic coast, they may also inhabit drier heathlands with low scrub.
Behavior and Diet
The western three-toed skink is a secretive creature. When threatened, it will quickly retreat into dense vegetation, hide under stones, or seek refuge in existing burrows. During the winter months, it hibernates deep underground, emerging in the late spring. Its diet primarily consists of a variety of invertebrate prey, which it actively hunts within its habitat.
Reproduction and Conservation
This species is viviparous, meaning females give birth to live young. Following a gestation period that can range from two to three months, a female may produce up to fifteen offspring, each approximately 10 cm (4 inches) long at birth. In some instances, the female may not survive this birthing process. The young reach maturity at around three to four years of age.
Globally, the western three-toed skink is classified as 'Least Concern' by the IUCN, owing to its extensive distribution and population density in certain regions. However, the species faces threats from the degradation of its habitat, largely driven by changes in agricultural practices. Despite being harmless, they are sometimes persecuted due to a mistaken belief that they are venomous.
