Description
The name Algerian sandfish originated because of its ability to move through sand as if it were swimming. Adult common skinks usually reach about 20 cm (8 inches) in length, including the short tail. The common skink has developed a peculiar surprise way of dealing with the desert heat: it can dive into loose, soft sand. Its winding movements produce vibrations in the sand, with a consistent frequency of 3 Hz. It does this to prevent overheating (as it is cold-blooded) and whenever it feels threatened, especially by its arch-nemesis, the devil-headed Saharan snake. This skink has a long, wedge-shaped snout with a countersunk lower jaw, shaped much like a basket. Its compact, tapered body is covered with smooth, shiny scales that may appear oily to the untrained eye, and its legs are short and sturdy with long, flattened and fringed shovel-like feet. The tail is short, tapering to a fine point. The coloration of this species is considered attractive, being yellow-caramel with brown-black cross bands. This lizard also has bead-like eyes so it can close them to keep sand out of its eyes. Similarly, its nostrils are very small to keep all of the sand out of its nose and lungs. The skink plays a small yet significant role in 13th century Islamic mythology originating in Algeria. To this day, nomadic tribes of the region believe that the skink's ability to avoid predators by diving into sand is a blessing that protects them from dangers of the desert and often keep the animal as a pet. X-ray imaging has demonstrated the lizard swims within sand using an undulatory gait with its limbs tucked against its sides rather than use its limbs as paddles to propel itself forward.

Species in the Scincus genus are distributed over an extensive belt of desert from the west coast of Africa, through the Sahara and into Arabia.Diet
The sandfish skink is anHardiness
Sandfish are strong and very resilient, since one of the most inhospitable(harsh and difficult) places to live is their home. They live in temperatures of 40 degrees Celsius(114 degrees Fahrenheit) during the day to -4 degrees Celsius(25 degrees Fahrenheit) during the night.Relatives
The sandfish has around 6 or 7 morphs. The sandfish is very similar to Peters's banded skink, a less wedge-nosed skink with different hands that are more similar to a blue tongue skink than a sandfish.References
