Chalcides sepsoides
The wedge-snouted skink (Chalcides sepsoides) is a common and widespread lizard found across North Africa and the Middle East, inhabiting sandy areas and dunes. This viviparous species is characterized by its reduced limbs, enabling it to efficiently "swim" beneath the sand as its primary escape tactic. It exhibits seasonal activity patterns, being nocturnal in summer and diurnal in winter.

About Chalcides sepsoides
Wedge-Snouted Skink (Chalcides sepsoides)
The wedge-snouted skink, scientifically known as Chalcides sepsoides, is a common and widely distributed species of skink found across North Africa and the Middle East. Its range encompasses countries such as Tunisia, Libya, Egypt, Israel, Jordan, and the Palestinian territories. This lizard is a specialist of sandy environments, thriving in areas like sand dunes, open steppe, and bushland characterized by sandy soil.
Physical Adaptations and Behavior
A defining characteristic of Chalcides sepsoides is its remarkable adaptation for a fossorial lifestyle. The species possesses greatly reduced limbs, which facilitate its efficient movement by "swimming" beneath the sand. As a result, it is rarely observed on the ground's surface, preferring to remain hidden underground. Its primary defense mechanism involves diving into the sand to escape predators. The activity patterns of the wedge-snouted skink are influenced by the seasons; it is nocturnal during the hot summer months and becomes diurnal, active during the day, throughout the winter.
Ecology and Conservation
Chalcides sepsoides is a viviparous species, meaning that females give birth to live young. While generally considered common and stable in population, the species can face localized threats. These include habitat loss due to various land-use changes, overgrazing by livestock, and collection for commercial purposes. However, these pressures are not currently viewed as severe enough to endanger the species as a whole, and its population is reported to be stable.

Sphenops sepsoides
Sphenops sepsoides, also known as the wedge-snouted skink, is a common and widespread skink species found across North Africa and the Middle East. This viviparous lizard is a sand specialist, adept at 'swimming' beneath the sand with its reduced limbs, rarely emerging onto the surface. It inhabits sandy areas and dunes, exhibiting nocturnal behavior in summer and diurnal activity in winter.
Tiliqua occipitalis
The western blue-tongued lizard (Tiliqua occipitalis) is a large skink native to Australia, known for its distinctive blue tongue and brown, banded pattern. It inhabits grasslands, dunes, and shrublands, and is a diurnal hunter of insects, snails, and carrion, also foraging for plants. This species is notable for its slow-moving prey preference due to its less agile nature and powerful jaws capable of crushing shells.
Acanthodactylus scutellatus
The Acanthodactylus scutellatus, commonly known as the Nidua fringe-fingered lizard, is a small lizard species endemic to northern Africa and the Middle East. It is recognized by its unique ventral scale arrangement and its adeptness at burrowing in loose sand for shelter. This diurnal species breeds in late winter, with females laying clutches of 3-6 eggs in the spring.
