Wedge-snouted Skink

C. sepsoides occurs in sandy areas and dunes, including open steppe and bushland with sandy soil. It is nocturnal during the summer and diurnal during the winter. It is a common species that can be locally threatened by habitat loss, overgrazing, and commercial collection, although none of these threats are considered to be very serious, and the species population is stable.

S. sepsoides is a viviparous species. C. sepsoides is subarenaceous, and it moves very efficiently by "swimming" under the sand. In fact, it is rarely seen about the ground, and a common method of capturing specimens is to dig through sand dunes near the bases of bushes; this is because its main escape tactic is to dive into the sand. Its limbs are greatly reduced as an adaptation to this fossorial movement. As a result, it is often considered to be a sand specialist.
