Axolotls require a moist environment to survive, as they rely on their skin for cutaneous respiration, which allows them to absorb oxygen from the water. If an axolotl is removed from water, it can start to experience dehydration and desiccation, which can be harmful or even fatal. However, the rate at which an axolotl dries out depends on various factors, including:
Ambient Humidity: In a humid environment, an axolotl will dry out more slowly than in a dry environment.
Temperature: Higher temperatures can speed up the evaporation of moisture from the axolotl's skin, leading to faster desiccation.
Surface Area: Larger axolotls may have more surface area exposed to the air, potentially leading to quicker drying.
Airflow: Increased airflow, such as from a fan or draft, can accelerate the drying process.
Skin Condition: Healthy skin with a good mucous layer can retain moisture longer.
Under normal conditions without water, an axolotl could start showing signs of dehydration within a few hours, but the exact time can vary based on the factors mentioned above. To keep an axolotl healthy, it should not be left out of water for extended periods. If you need to handle an axolotl, it's best to do so quickly and return it to its water habitat immediately afterward. If you must keep an axolotl out of water, it's essential to provide a damp environment, such as a container lined with a wet sponge or cloth, to help maintain the necessary moisture levels.
