### Identification At first glance, you might mistake this "sand-swimmer" for a small snake, but look closer at its high-gloss, cylindrical body. The Cape Striped Legless Skink (*Acontias parietalis*) typically reaches 15–22 cm in length. Its most striking field mark is the pattern: a pale straw-yellow or silvery-grey base decorated with four to six bold, dark chocolate-brown longitudinal stripes that run from the snout to the tip of the tail. Unlike snakes, it lacks a narrowed neck and has a notably blunt head and tail, giving it a "double-ended" appearance. Its eyes are minute, covered by a transparent, non-movable scale (a spectacle), which protects them while burrowing.
### Habitat & Range This species is a specialist of the Western Cape of South Africa. It is almost exclusively found in the fynbos biome, particularly in coastal lowlands where the soil is sandy and friable. They are most common in the "strandveld" vegetation, where they utilize the loose substrate beneath sandstone rocks or the leaf litter of proteas and restios. They rarely venture into heavy clays or rocky mountain peaks, preferring elevations near sea level.
### Behaviour To find *A. parietalis*, you must be a "turner of stones." They are fossorial (burrowing) and spend nearly their entire lives submerged. When exposed, they exhibit a frantic "sand-swimming" motion—high-frequency lateral undulations that allow them to vanish into the soil in seconds. They are largely solitary and move closer to the surface during the damp winters to hunt, retreating deeper during the parched summer months to avoid desiccation.
### Diet These skinks are the "underground cleaners" of the fynbos. They forage by scent and vibration, hunting for soft-bodied invertebrates. Their diet consists primarily of beetle larvae, small earthworms, and termites. Their smooth, reinforced skulls allow them to push through soil to corner prey in their own tunnels.
### Fascinating Fact As its name *parietalis* suggests, this lizard possesses a remarkably prominent parietal eye—a "third eye" located on the top of its head. While it doesn't see images, this light-sensitive organ allows the skink to sense changes in light and shadow through the sand, helping it track the sun’s position to thermoregulate without ever fully emerging into the open!
