Understanding Crested Geckos


Crested geckos (Correlophus ciliatus) are small to medium-sized reptiles known for their distinct appearance and unique characteristics. They belong to the family Diplodactylidae and are endemic to the rainforests of New Caledonia, a group of islands located in the southwestern Pacific Ocean.


In their natural habitat, they thrive in a tropical environment with high humidity and moderate temperatures. The rainforests of New Caledonia provide them with a diverse range of microhabitats, including tree trunks, branches, and leaf litter. These geckos are primarily arboreal, spending their lives in the trees and utilizing their specialized feet and prehensile tails for climbing.


Crested geckos have evolved to adapt to the fluctuating temperatures of their natural environment. In the wild, they regulate their body temperature by utilizing different microhabitats within the rainforest. They bask in warmer areas exposed to sunlight to raise their body temperature, and they seek cooler, shaded areas to lower their body temperature when necessary. This behavior allows them to maintain their optimal body temperature, essential for their metabolic processes and overall well-being.


Unlike some reptiles, crested geckos do not require intense heat sources like desert-dwelling species. They prefer moderate temperatures ranging from 72°F to 80°F (22°C to 27°C), with a slight drop at night. It’s important to replicate these temperature ranges as closely as possible within their captive environment to ensure their physiological functions are properly supported.


Understanding how crested geckos naturally regulate their body temperature in the wild provides valuable insights into the heating requirements necessary for their captive care. By creating an environment that mimics their natural habitat, we can help ensure their health and well-being as captivated pets.
