Taxonomic History and Classification Changes
Throughout the years, the taxonomic history and classification of the crested gecko, scientifically known as Correlophus ciliatus, has undergone significant changes and revisions.
This species was first described in 1866 by Alphone Guichenot as Correlophus ciliatus, but it was later renamed Rhacodactylus ciliatus.
However, recent phylogenetic analysis has led to the reclassification of 55 species from Rhacodactylus back to Correlophus.
The specific name, ciliatus, refers to the crest of skin over the animal’s eyes resembling eyelashes.
These taxonomic changes highlight the ongoing efforts to better understand the genetic relationships and evolutionary history of the crested gecko.
Description of the Crested Gecko
The crested gecko, scientifically known as Correlophus ciliatus, exhibits a unique set of physical characteristics that distinguish it from other gecko species. This species ranges from 8 to 10 inches in length, including the tail.
One of its most distinctive features is the presence of eyelash-like projections above its eyes. These geckos also have a semi-prehensile tail, which they use for climbing and can be dropped as a defense mechanism to distract predators. The toes and tail are covered in small hairs called setae, which aid in climbing.
The crested gecko displays various color morphs, including shades of grey, brown, red, orange, and yellow. These physical attributes contribute to the overall uniqueness of this fascinating species.

Ecology and Behavior of the Species
Inhabiting the lush rainforests of New Caledonia, the crested gecko demonstrates a predominantly arboreal lifestyle. Here are four fascinating facts about the ecology and behavior of this species:
- Nocturnal Habits: The crested gecko is primarily active at night, seeking secure spots to sleep during daylight hours.
- Varied Diet: These geckos have an omnivorous diet, feeding on a range of foods including fruit, nectar, pollen, and insects.
- Rediscovery: The crested gecko was previously believed to be extinct until its rediscovery in 1994, making it a species of great interest to biologists.
- Conservation Concerns: The wild population of crested geckos faces threats from introduced species and habitat damage, highlighting the need for conservation efforts.
Understanding the ecology and behavior of the crested gecko is crucial for ensuring its survival in its natural habitat.
Threats to the Wild Population
The wild population of crested geckos faces significant threats to their survival in their natural habitat. One of the main threats is the introduction of non-native species. These invasive species, such as rats and cats, prey on the geckos and compete with them for resources.
Additionally, habitat degradation poses a major risk to the wild population. Deforestation, wildfires, and human activities such as mining and agriculture result in the loss and fragmentation of the geckos’ habitat. This disrupts their natural behaviors, limits their access to food and shelter, and reduces their chances of survival.
Conservation efforts are crucial to mitigate these threats and protect the remaining wild population of crested geckos.
Reproductive Behavior and Breeding Cycle
Limited information is available on the reproductive behavior and breeding cycle of crested geckos in the wild, with most knowledge being obtained from captive animals. However, understanding these aspects is crucial for the conservation of this rediscovered rare species.
Here are four key points about the reproductive behavior and breeding cycle of crested geckos:
- Clutch size: Females lay two eggs per clutch, which is a relatively small number compared to other gecko species.
- Incubation period: The eggs of crested geckos hatch after a period of 60-150 days, indicating a relatively long incubation period.
- Breeding cycle: Females can lay eggs every 4-6 weeks, suggesting a breeding cycle of approximately 8-10 months.
- Cooling cycle: After breeding, female geckos undergo a cooling cycle to regain body mass and nutrients, which is an important part of their reproductive process.
Understanding the reproductive behavior and breeding cycle of crested geckos is essential for their successful conservation and management in both captive and wild populations. Further research is needed to uncover more details about these aspects in their natural habitat.
Incubation Period and Hatching
Understanding the reproductive behavior and breeding cycle of crested geckos is crucial for their conservation, and a key aspect of this is the incubation period and hatching process. Limited information on wild reproductive behavior has been obtained mostly from captive animals. Females lay two eggs per clutch, which hatch after an incubation period of 60-150 days. Females can lay eggs every 4-6 weeks, resulting in a breeding cycle of 8-10 months. It is important for females to undergo a cooling cycle after breeding to regain body mass and nutrients. Calcium deficiency can occur in egg-laying females if they do not have enough calcium. The table below provides a summary of the incubation period and hatching process for crested geckos:
| Aspects | Incubation Period | Hatching Process |
|---|---|---|
| Eggs per clutch | 2 | |
| Incubation period | 60-150 days | |
| Breeding cycle | 8-10 months | |
| Cooling cycle |
Importance of Calcium in Egg-Laying Females
Calcium plays a crucial role in the reproductive health of egg-laying females. Here are four reasons why calcium is important for these females:
- Eggshell Formation: Calcium is a vital component for the formation of strong and healthy eggshells. It provides the necessary structural support to protect the developing embryos.
- Muscle Function: Calcium is essential for proper muscle function, including the contraction of muscles involved in egg laying. Without sufficient calcium, females may experience muscle weakness, leading to difficulties in laying eggs.
- Skeletal Health: Calcium is necessary for maintaining strong and healthy bones. Egg-laying females need to replenish the calcium stores depleted during egg production to prevent bone weakness and fractures.
- Hormone Regulation: Calcium is involved in hormone regulation, including the production and release of reproductive hormones. Adequate calcium levels ensure proper hormonal balance, which is crucial for successful egg laying.
