do mexican salamanders always survive without water during everytime of their entire lifetime

Mexican axolotls (Ambystoma mexicanum) are primarily aquatic creatures and require water to survive for most of their lives. They breathe through gills when they are young and through lungs as adults, but they still need to stay moist. Here are some key points to consider:

1. Aquatic Habitat: Axolotls spend most of their lives in water, where they hunt for food and breed. They are not well-adapted to life on land.

2. Limited Terrestrial Activity: Although they can move on land using their limbs, they do so only for short periods. Their skin needs to stay moist, and they cannot survive for extended periods without water.

3. Hibernation: In colder months, axolotls may burrow into the mud at the bottom of ponds or lakes to hibernate. During this time, they enter a state of reduced metabolism and can survive without eating for several months.

4. Water Quality: Axolotls are sensitive to water quality and require clean, oxygen-rich water to thrive. Poor water quality can lead to health problems and even death.

In summary, while Mexican axolotls have some limited ability to move on land, they are fundamentally aquatic animals that depend on water for survival. They cannot survive without water during most of their lives. It is essential to provide them with a suitable aquatic environment to ensure their well-being.
