Axolotls are amphibians that typically inhabit freshwater environments and are capable of living underwater. They breathe through gills when they are in their larval stage and, as adults, primarily through lungs. However, even adult axolotls also utilize cutaneous respiration (breathing through their skin), which requires them to maintain moist skin, often by staying submerged in water.
Here are some key points about axolotls' ability to live underwater:
Gills in Larvae: As larvae, axolotls breathe entirely through external gills.
Lung Breathing as Adults: As they mature, axolotls develop lungs and primarily use them for respiration. However, even adults can use their skin for supplementary breathing.
Cutaneous Respiration: Axolotls can absorb oxygen through their skin when it is wet, allowing them to stay underwater for extended periods.
Moisture Requirement: To maintain effective cutaneous respiration and prevent dehydration, axolotls need to be in water or a moist environment.
Habitat: In the wild, axolotls are found in lakes, ponds, and slow-moving rivers, where they can easily access both water and air.
Feeding: Axolotls are carnivorous and hunt for food underwater, so they are well-adapted to an underwater lifestyle for foraging.
While axolotls can live primarily underwater, they still require occasional access to air or a moist environment to maintain their skin's health and ensure proper respiration. They are not continuously underwater breathers like fish, but their unique respiratory capabilities allow them to thrive in aquatic environments.
