can axolotls be dry out eventually after leaving water for very long period of time

Yes, axolotls require a moist environment to survive, and they can dry out and potentially be harmed if left out of water for an extended period. Here are key points to consider regarding their care:

1. Skin Respiration: Axolotls breathe through their skin, which requires a film of water or moisture to facilitate gas exchange. Dry conditions can impair their ability to breathe.

2. Hydration: Their soft, permeable skin is designed to stay moist and help them absorb water to maintain hydration.

3. Desiccation Dangers: Extended exposure to air can lead to desiccation, where the skin dries out. This condition can cause stress, health issues, and even death.

4. Handling: When handling axolotls, it's crucial to keep them moist and return them to their water habitat promptly to prevent the risk of drying out.

5. Habitat: Ensure their aquatic environment has clean, well-maintained water with appropriate temperature and pH levels. Adding hiding spots can also help maintain a moist micro-environment.

6. Careful Monitoring: Monitor axolotls closely when they are out of water for any reason, such as during feeding or cleaning their habitat.

7. Quick Returns: If you need to remove an axolotl from its habitat, make sure to return it to the water as quickly as possible to minimize the time it spends in a dry environment.

In summary, while axolotls have some tolerance for short periods out of water, they should not be left out for extended periods due to the risk of dehydration and skin damage. Always handle them gently and return them to their aquatic environment promptly to ensure their health and well-being.
