Why can amphibians live in land and water?
They can extract oxygen from the atmosphere in their environment through their skin and also have gills.
Not all amphibians can live both on land and in the water at the same time. Some can only live in the water for their entire life, while others can alternate between living on land and in the water depending on their needs. Many amphibians have gills in one stage of their life cycle and not in another.

Amphibians can live in both land and water due to their unique adaptations, including permeable skin, specialized respiratory systems (gills for aquatic respiration and lungs for terrestrial respiration), and ability to regulate water and salt balance. These adaptations allow them to effectively exchange gases and absorb moisture from both environments, enabling them to thrive in diverse habitats.
