Leiocephalus – Curly-tailed lizards

Can be seen performing push-ups or displaying their brightly colored underbellies to warn off rivals or signal to potential mates

Leiocephalidae, commonly known as curly-tailed lizards, are a vibrant and distinctive group of reptiles predominantly found in the Caribbean, with a wide variety in size, color, and behavior. These lizards are particularly noted for their unique tail, which curls over the back in a distinctive spiral when the lizard is excited or on alert, giving them their common name. This feature isn’t just for show; it plays a role in communication among lizards and possibly in courtship displays.

Curly-tailed lizards vary greatly in size depending on the species, typically ranging from 10 to 20 cm (4 to 8 in) in length. They possess robust bodies and large, scaly heads, with males often being larger and more vividly colored than females. The coloration of these lizards can be quite striking—ranging from greens and browns that blend into their natural surroundings to brighter blues and reds found in some species. This variety of colors not only helps in camouflage but also plays a role in attracting mates and deterring predators.

One of the fascinating aspects of Leiocephalidae is their adaptability to different environments. While they are mainly found in rocky areas and dry forests, some species have adapted to urban areas, thriving in city parks and gardens where they can be seen basking in the sun on rocks or sidewalks. They are diurnal, meaning they are active during the day, and are primarily terrestrial, although they can climb if needed.

Diet-wise, curly-tailed lizards are opportunistic feeders. They primarily eat insects, such as ants and beetles, but can also consume fruit, smaller reptiles, and even small mammals, making them important for controlling pest populations. Their feeding habits also make them key players in their ecosystems, helping to maintain a balance between the populations of their prey.
