can axolotls completely live without water for all lifetime

No, axolotls cannot live their entire lives without water. As an aquatic species native to Mexico, they require water for the following reasons:

1. Respiration: They primarily breathe through gills while in water, which is essential for their respiratory processes.

2. Hydration: Their permeable skin needs to be kept moist to prevent dehydration, which can be life-threatening.

3. Thermoregulation: Axolotls rely on water to regulate their body temperature and maintain the appropriate conditions for their metabolic processes.

4. Feeding: They are predators that hunt and consume invertebrates and small fish, which usually occurs in their aquatic environment.

5. Reproduction: Mating and offspring development take place in water.

While they can survive briefly out of water due to their ability to absorb some oxygen from the air, their long-term survival is not possible without a proper aquatic habitat. Axolotls need a suitable aquatic environment with clean water, the right temperature, and adequate humidity to thrive and live a healthy life.
