Axanthic Crested Gecko: The Monochrome Marvel of the Reptile World

Axanthic Crested Geckos, a stunning morph of the Correlophus ciliatus, are celebrated for their unique grayscale appearance, making them a captivating addition to the reptile hobby. Unlike their colorful counterparts, these geckos lack the yellow pigmentation, giving them a monochromatic elegance that stands out. In this article, we’ll explore the characteristics, genetics, care requirements, lifespan, pricing, and the increasing popularity of Axanthic Crested Geckos.

Axanthic Crested Geckos Physical Characteristics

Axanthic Crested Geckos

Axanthic Crested Geckos are distinguished by their lack of xanthophores, the cells responsible for yellow and red pigments, resulting in a striking range of blacks, grays, and whites. This absence of color leads to a unique, almost ethereal appearance, highlighting the intricate patterns and textures of their skin. Their skin is typically smooth and velvety, and the patterns can vary widely from one individual to another, ranging from bold contrasts to subtle, blended tones. The prominent crests, which run from the eyes down to the tail, add to their prehistoric allure. Adult Axanthic Crested Geckos usually reach a length of 8 inches, including the tail, and can weigh between 35 to 55 grams.

Genetics and Breeding

The axanthic trait in Crested Geckos is due to a recessive genetic mutation. For a gecko to exhibit this grayscale appearance, it must inherit the axanthic gene from both parents. This makes breeding for axanthicism a deliberate and careful process. When an axanthic gecko is bred with a non-axanthic one, the offspring will be heterozygous, carrying the axanthic gene without displaying the trait. To produce axanthic offspring, two heterozygous carriers must be bred together, with a 25% chance of resulting in an axanthic gecko. The recessive nature of the gene and the intricate breeding process contribute to the rarity and value of these geckos.

Axanthic Crested Geckos Habitat and Care Requirements

Creating a suitable habitat for Axanthic Crested Geckos involves replicating their natural environment found in New Caledonia’s rainforests. Here’s a detailed guide to their care requirements:

  1. Enclosure Size: A vertical terrarium of at least 20 gallons is ideal for a single adult. Since these geckos are arboreal, providing ample vertical space for climbing is crucial. Multiple hiding spots and climbing structures, such as branches and vines, should be included.
  2. Temperature and Humidity: Maintain a daytime temperature range of 70-80°F (21-27°C) and allow for a slight nighttime drop to around 65°F (18°C). Humidity levels should be kept between 50-70%, which can be achieved through regular misting and a substrate that retains moisture.
  3. Substrate: Suitable substrates include coconut fiber, sphagnum moss, or a commercial reptile substrate designed to hold moisture. These substrates help maintain the necessary humidity and provide a naturalistic environment for the gecko to explore and burrow.
  4. Lighting: While not essential, a low-level UVB bulb can aid in vitamin D3 synthesis and overall health. Providing a natural light cycle of 12 hours of light and 12 hours of darkness is beneficial for their biological rhythms.
  5. Diet: Axanthic Crested Geckos thrive on a diet of commercial Crested Gecko food, which offers a balanced mix of fruits, proteins, and nutrients. This should be supplemented with occasional fresh fruits and live insects like crickets or dubia roaches to ensure a well-rounded diet.

Axanthic Crested Geckos Lifespan

With proper care, Axanthic Crested Geckos can live for 15 to 20 years in captivity, making them a long-term commitment. Their lifespan is influenced by factors such as diet, habitat conditions, and overall health management. Regular veterinary check-ups, maintaining optimal enclosure conditions, and providing a balanced diet are essential for ensuring a long and healthy life for these geckos.

Axanthic Crested Geckos Price and Market Value

Axanthic Crested Geckos are highly prized due to their rarity and unique appearance, often fetching higher prices in the market compared to other Crested Gecko morphs. Prices can vary significantly based on factors such as lineage, quality of the axanthic traits, and the specific breeder. On average, an Axanthic Crested Gecko can cost between $300 to $800, with particularly high-quality or rare lineage specimens potentially exceeding $1,000. The complexity of breeding and the demand for these geckos contribute to their higher market value. As the popularity of exotic reptile morphs continues to grow, the price and demand for Axanthic Crested Geckos are expected to remain strong.

Popularity and Collectibility

The unique aesthetic of Axanthic Crested Geckos has made them a favorite among collectors and reptile enthusiasts. Their rarity and striking appearance add to their allure, making them a coveted addition to any reptile collection. The growing interest in reptile morphs and the fascination with genetic diversity further drive their popularity. Breeders are increasingly focused on producing high-quality axanthic specimens, leading to a thriving market for these geckos. The challenge of breeding for the axanthic trait and the satisfaction of owning such a distinctive gecko make them an attractive choice for hobbyists.

Conservation and Ethical Considerations

While Crested Geckos, including the axanthic morph, are not currently listed as endangered, it is important to support ethical breeding practices and conservation efforts. Many Crested Geckos in the pet trade are bred in captivity, reducing the pressure on wild populations and helping to preserve their natural habitats. Choosing reputable breeders who prioritize the health and well-being of their animals and adhere to ethical practices ensures the continued availability of these geckos and supports conservation. Additionally, participating in conservation initiatives and supporting organizations dedicated to preserving natural habitats contribute to the long-term survival of Crested Geckos and other reptile species.


The Axanthic Crested Gecko is a remarkable and highly sought-after morph of the Crested Gecko, celebrated for its unique grayscale coloration and genetic rarity. With proper care, these geckos can thrive in captivity, providing a fascinating glimpse into the diversity of reptile morphs. Whether you’re a seasoned reptile enthusiast or a beginner looking to expand your collection, the Axanthic Crested Gecko offers a unique and rewarding experience. Understanding their specific care requirements, respecting their natural behaviors, and supporting ethical breeding practices ensure that these monochromatic marvels continue to captivate and charm reptile enthusiasts for many years to come. As interest in exotic reptile morphs continues to grow, the Axanthic Crested Gecko stands out as a symbol of the beauty and diversity found within the reptile world.
