can axolotls completely live without water for all their lifetime

No, axolotls cannot completely live without water for their entire lifetime. Axolotls are amphibians, specifically neotenic salamanders, which means they retain certain larval features like gills into adulthood and are specially adapted for an aquatic lifestyle. Key reasons why they cannot survive entirely out of water include: 1. **Respiratory Needs**: Axolotls primarily use gills to breathe, which are efficient in water but not functional in air. 2. **Skin Function**: Their skin is permeable and needs to stay moist for respiration and excretion. 3. **Body Structure**: Axolotls have a soft body that lacks the muscular development for effective movement on land. 4. **Hydration**: Axolotl skin needs to stay hydrated to function properly, and dehydration quickly becomes an issue out of water. 5. **Life Cycle**: All stages of the axolotl life cycle, from eggs to adults, are aquatic. 6. **Temperature Regulation**: Axolotls rely on the water to help regulate their body temperature. 7. **Feeding Habits**: Axolotls hunt for aquatic prey, and their feeding mechanisms are adapted for underwater environments. 8. **Health and Well-being**: Living without water would lead to stress, health issues like skin damage, and likely death. Providing axolotls with a proper aquatic environment is essential for their survival and well-being.
