Axolotls, also known as Mexican Walking Fish, are renowned for their striking variety of color morphs, each contributing to the allure of these fascinating creatures.
These amphibians, which retain their larval features throughout their life, come in an impressive array of colors, ranging from wild types with dark hues to leucistic axolotls with their brilliant white tones.
This article dives into the 13 types of axolotl colors and morphs, along with the genetic reasons behind these captivating variations.
The 13 Types of Axolotl Colors & Morphs
Here is a list of 13 Types of Axolotl Colors & Morphs

1. Wild Type
The wild type axolotl is characterized by a dark hue, usually a combination of greens, blacks, and browns. Their coloration serves as an effective camouflage in their natural habitats.
2. Leucistic
Leucistic axolotls are pure white or pink with striking black or dark blue eyes. Unlike albinos, they can produce melanin, but it’s generally absent from their skin.
3. Golden Albino
Golden albino axolotls showcase a lovely range of gold, peach, and pink hues. They have clear or red eyes due to the lack of melanin and the visibility of blood vessels.
4. White Albino
White albinos, as their name suggests, are completely white and have clear or red eyes. This color morph is quite rare and sought after in the pet trade.
5. Melanoid
Melanoid axolotls exhibit solid black or very dark brown color. Unlike wild types, they lack iridophores and xanthophores, which gives them their uniform coloration.
6. Copper
The copper axolotl is a relatively new color morph, showcasing a beautiful range of burnt orange and copper tones. Their eyes are generally light-colored.
7. Silver Dalmatian
Silver Dalmatians exhibit a pale or light silver color with darker freckles or spots throughout their bodies, giving them the name.
8. GFP (Green Fluorescent Protein)
GFP axolotls have been genetically modified to produce a protein that makes them glow green under UV light. They can be any color morph but are commonly found in leucistics.
9. Mosaic
Mosaic axolotls are the result of two fertilized cells merging, producing an axolotl with two different types of cell, which often leads to a mix of two color morphs.
10. Chimera
Similar to mosaics, chimeras result from the fusion of two embryos, leading to an axolotl with two different color morphs, usually split down the middle.
11. Enigma
Enigma axolotls are characterized by their irregular and random patches of pigmentation, making each individual unique.
12. Piebald
Piebald axolotls exhibit patches of unpigmented white or pink skin mixed with a base color, similar to a dappled horse.
13. Lavender
Lavender axolotls, a newer morph, showcase a delicate mix of purples, pinks, and greys, giving them a ‘lavender’ appearance.
The Science Behind Axolotl Color Variations
The diversity in axolotl colors and morphs results from the interaction of various genes that control pigmentation.
Three primary layers of pigment cells, known as chromatophores, determine the axolotl’s final color.
These include melanophores (black/brown pigments), xanthophores (yellow/red pigments), and iridophores (reflective/glowing pigments).
The presence, absence, or modification of these chromatophores due to genetic factors results in the different axolotl color morphs.

From the natural hues of the wild type to the unique glow of the GFP axolotl, the diverse color palette of axolotl morphs is truly captivating.
Each axolotl color morph brings a different aesthetic appeal, adding to the intrigue and charm of these amazing creatures.
By understanding the genetics behind these color variations, we can appreciate these splendid creatures even more.
Whether you’re an axolotl enthusiast or considering one as a pet, we hope this comprehensive guide to axolotl colors and morphs enhances your admiration for these remarkable creatures and aids in making informed choices.
FAQs About Axolotl Colors
1. What are the most common colors of axolotls?
- Wild Type: Dark brown or black with speckled patterns.
- Leucistic: Pale pink with red or pink eyes.
- Albino: White or pale yellow with red eyes.
- Melanoid: Solid black with a smooth, glossy appearance.
- Golden Albino: Yellowish with red eyes.
- Copper: A deep red-brown with a coppery sheen.
2. Can axolotls change color?
While axolotls do not change color significantly, their color can appear different based on their environment and lighting. For instance, stress or diet changes can sometimes cause slight variations in their coloration.
3. What causes the different colors in axolotls?
The different colors in axolotls are due to genetic variations. These color variations are the result of specific gene expressions that affect pigment production and distribution.
4. Are certain axolotl colors more rare or expensive?
Yes, some colors are rarer and therefore more expensive. For example, the leucistic and albino varieties are more common and usually less expensive, while the golden albino and some unique morphs can be more costly.
5. How do I care for axolotls of different colors?
The care for axolotls is generally the same regardless of color. Ensure they have a suitable habitat with clean water, appropriate temperature, and a proper diet. Special attention might be needed for maintaining the brightness of their colors, particularly for albino and leucistic axolotls, which are more sensitive to light.
6. Do axolotls’ colors affect their health?
The color of an axolotl does not directly affect its health. However, albino and leucistic axolotls may be more sensitive to light and may require more careful handling to avoid stress and potential eye damage.
7. Can axolotls change color as they age?
Axolotls generally maintain their color throughout their life. However, as they grow older, some changes in hue or brightness can occur, especially due to environmental factors or changes in health.
8. What are some unique or rare axolotl colors?
Unique or rare colors include the Raspberry Albino, Black Melanoid, and Mosaic, which are less common and often sought after by collectors.
9. How can I determine the color of a baby axolotl?
The color of a baby axolotl can sometimes be difficult to determine accurately until it matures. Observing the hatchling’s coloration and patterns over time will give a clearer indication of its final color.
10. Are there any special considerations for breeding axolotls with specific colors?
Breeding axolotls for specific colors involves understanding genetics and ensuring that both parents carry the desired genes. Some color morphs require careful pairing to produce offspring with the correct coloration.
11. How do environmental factors affect axolotl colors?
Environmental factors such as water quality, light exposure, and diet can influence the appearance of an axolotl’s color. Maintaining a stable and clean environment helps in preserving their vibrant colors.
12. Can axolotls with different colors breed with each other?
Yes, axolotls of different colors can breed with each other. The offspring’s colors will depend on the genetic makeup of both parents and can result in a variety of color morphs.
13. Are there any color variations in wild axolotls?
Wild axolotls typically exhibit a dark brown or black coloration with speckles. This coloration helps them blend into their natural environment in the wild.
14. What should I look for when buying an axolotl with a specific color?
When buying an axolotl, ensure it is from a reputable breeder or pet store. Check the axolotl’s overall health, including its color, skin condition, and behavior, to ensure it is well cared for.
15. Can the color of an axolotl be an indicator of its age or health?
While color itself is not a direct indicator of age or health, changes in coloration can sometimes signal health issues. A sudden or significant change in color should be evaluated by a vet to rule out health problems.
