will mexican salamanders eventually be unhealthy if survive without water completely

Yes, completely removing Mexican salamanders from a water source can lead to serious health issues and is not recommended. Here's why: 1. **Respiration**: Salamanders, including Mexican species, rely on their moist skin for gas exchange. Without water, their skin dries out, impeding this process and leading to respiratory distress. 2. **Hydration**: Water is crucial for maintaining hydration. Dehydration can weaken them and make them more susceptible to illness. 3. **Skin Health**: Their permeable skin needs to stay moist to function properly. Dry conditions can cause it to crack, increasing vulnerability to infections. 4. **Stress**: Being in an unnatural environment can cause stress, which can weaken their immune system and overall health. 5. **Reproduction**: Salamanders typically lay their eggs in water. A lack of water would impair their ability to reproduce. In summary, completely depriving Mexican salamanders of water is detrimental to their health and well-being. It's essential to provide them with a suitable aquatic habitat or a moist environment to ensure their health and survival. Always consult with a veterinarian or an amphibian care specialist if you have concerns about your salamanders' health.
