About Northern curly-tailed lizard
The Northern Curly-Tailed Lizard
The Northern curly-tailed lizard, scientifically designated as Leiocephalus carinatus, is a distinctive reptile recognized for its robust build and the characteristic upward curl of its tail. This species belongs to the family Leiocephalidae, commonly known as curly-tailed lizards. Its appearance is somewhat reminiscent of lizards from the genus Sceloporus, particularly due to its keeled and pointed dorsal scales.
Distribution and Habitat
Naturally, the Northern curly-tailed lizard is found across the Bahama Islands, the Cayman Islands, and Cuba. It has also established introduced populations in other regions. Notably, it was intentionally introduced to Palm Beach, Florida, in the 1940s with the aim of controlling sugar cane pests, and it now inhabits several other areas within the state. Another introduced population exists on Swan Islands in Honduras. The lizard thrives in sunny environments that provide loose rubble and rock formations, which it uses for shelter and basking. It is primarily a terrestrial species, preferring to stay on the ground and retreating into burrows or cavities when it feels threatened.
Behavior and Defense Mechanisms
This is an active and hardy lizard, predominantly living on the ground. When frightened, it will quickly seek refuge in a burrow or a suitable cavity. In some observations, captive specimens have been noted to burrow completely under sand even when alternative retreats like rocks were available. A particularly interesting behavior is its ability to 'play dead' when handled; it will remain completely motionless for a short period after being placed down. The Northern curly-tailed lizard also employs tail curling as a defense mechanism when being pursued. This behavior is most often observed when the predator is at a distance, serving as a deterrent or intimidation tactic. However, if the predator is close, the lizard prioritizes immediate escape and refuge.
Physical Characteristics
Adult Northern curly-tailed lizards typically reach a snout-to-vent length (SVL) of approximately 10.5 cm (4.1 inches). Including its tail, the total length can extend to about 26 cm (10 inches). The scales along its back are distinctly keeled and pointed, contributing to its somewhat rough texture. The most striking physical feature, aside from its scales, is its tail, which is commonly held in a curled upward position, especially when the lizard is resting horizontally on rocks or the ground.
