Scincus scincus
Encyclopedia
The Sandfish is a species of skink
that burrows into the sand and swims through it. It is native to North africa and southwestern asia, but is also kept as a pet elsewhere.
Adult sandfish usually reach about 8 inches (20 centimeters) in length, including the short tail.
The sandfish has developed a peculiar way of dealing with the desert heat: it possesses the ability to dive into the (soft) sand. It does this to prevent overheating (as it is cold blooded) and whenever it feels threatened.
The species has a long, wedge-shaped snout with a countersunk lower jaw. Its long, tapered body is covered with smooth, shiny scales, and its legs are short and sturdy with long, flattened and fringed feet. The tail is short, tapering to a fine point. The colouration of this species is considered attractive, being yellow-caramel with brown-black cross bands. This type of lizard also has bead-like eyes so they can close them to keep sand out of their eyes. Similarly its nostrils are very small to keep all of the sand out of its nose and lungs.
X-ray imaging has demonstrated that 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.
This species is very simple to care for, but rarely breeds in captivity. For this reason most animals in pet trade are wild caught.
