    Iguanidae – Iguanas & allies

    They only look dangerous!

    A large and diverse family includes some of the largest terrestrial lizards and the only marine lizards!

    Found throughout the western hemisphere (Canada, America, and the Caribbean mainly), iguanas primarily inhabit arid habitats. These lizards have a strong affinity for sunlight, as they require UV rays to synthesize vitamin D. As a result, they can often be found basking in the sun for extended periods.

    Iguanas are generally docile creatures, but they can become aggressive if threatened. They are territorial and use various displays, such as head bobbing and tail lashing, to communicate with each other.

    Despite their terrestrial nature, iguanas are proficient swimmers and are known to inhabit areas near water bodies. In fact, the Green iguana can remain submerged underwater for up to 28 minutes without needing to breathe.

    Despite their intimidating appearance, with sharp claws and strong jaws, iguanas are herbivores, feeding primarily on vegetation. This dietary preference makes them relatively harmless to humans and has led to their popularity as pets. However, caring for iguanas as pets requires careful attention to their specific dietary and habitat needs, as well as their long lifespan.

    Due to their specialized requirements and unique behaviors, keeping iguanas as pets can be challenging and demanding. In many cases, it is preferable to appreciate these fascinating creatures in their natural habitat rather than attempting to domesticate them.

    Did you know?

    • Iguanas and chameleons have a specialized parietal eye, a small light-sensitive eye on the top of their head that may help detect predators or measure day length.
    • Like other reptiles, iguanids are ectothermic, relying on external heat sources to regulate their body temperature.
    • They strongly dislike cold climates.
    • Iguanas shed their skin regularly throughout their lives, with young ones shedding multiple times per year and older ones shedding less frequently, sometimes only once annually.
