The sandfish lizard, also known as the Angolan shovel-snouted lizard or *Meroles anchietae*, is a small, burrowing reptile found in the sandy deserts of southern Africa. This species has gained attention for its unique wriggling behavior, which serves several purposes.

1. Sand Displacement: The primary reason behind the sandfish lizard's wriggling motion is to displace sand effectively while burrowing. As the lizard moves forward, its wriggling action helps loosen and push the sand to the sides, creating a temporary tunnel. This efficient burrowing technique allows the lizard to quickly disappear into the sand when threatened or seeking shelter from extreme temperatures.

2. Escape Mechanism: The sandfish lizard's wriggling also acts as an escape mechanism when pursued by predators. By rapidly wriggling its body and diving into the sand, the lizard can effectively evade capture. Once underground, it can use its powerful limbs to dig deeper and seek refuge.

3. Heat Regulation: The sandfish lizard's wriggling behavior aids in regulating its body temperature. Burrowing into the sand helps the lizard escape from the scorching desert heat, finding cooler temperatures underground. The wriggling motion facilitates heat exchange and prevents overheating, ensuring the lizard's survival in the harsh desert environment.

4. Predatory Advantage: Although not a primary predator, the sandfish lizard occasionally hunts for small insects and invertebrates. Its wriggling motion can sometimes be observed during hunting, as it stealthily moves through the sand towards its unsuspecting prey.
