Northern Curly-Tailed Lizard

Fascinating facts about the Northern Curly-Tailed Lizard

• In the 1940s people deliberately released this lizard in Palm Beach, Florida to try to control sugar-cane pests. The introduction succeeded and the species now survives in several other Florida locations. A separate introduced group also lives on the Swan Islands of Honduras, showing its ability to establish beyond its native range. Its continued presence reflects the lasting impact of that early pest-control experiment.
• When pursued, the northern curly-tailed lizard lifts its tail in a conspicuous curl to ward off distant predators, a visual warning that can discourage further chase. If the threat draws nearer, the display is abandoned and the lizard darts for the nearest burrow or crevice, relying on its speed and terrestrial habit. This shift from intimidation to rapid refuge is typical of its active, robust nature, which favours sunny, rocky habitats.
• If a hand grabs the lizard, it will often play dead, remaining perfectly still for a brief period before resuming activity. This tonic immobility is a short-lived response that can make a predator lose interest. After the brief pause, the lizard quickly recovers and returns to its normal, active behaviour, ready to flee or hide as needed.
• When threatened this lizard will dig straight into sand, even if a solid rock shelter is nearby, showing a strong preference for burrowing as a refuge. In captivity a large Cayman Island specimen repeatedly buried itself completely under the substrate despite a rock hide being offered. If seized it can enter a brief tonic immobility, remaining perfectly still for a short time before resuming activity.
• The northern curly-tailed lizard is easily recognised by the upward curl of its tail when it lies flat on rocks or the ground, a posture that sets it apart from similar Sceloporus lizards. This curled tail is not merely decorative; the species uses it as an antipredator display when a predator is at a distance, attempting to intimidate the pursuer.
