Amphibians, such as frogs, toads, and salamanders, typically live near water due to their unique life cycle and physiological needs. Most amphibians start their life in aquatic environments as eggs or larvae, a stage that requires water for survival.
During the larval stage, amphibians breathe through gills while developing into adult forms, which often involve transitioning to air-breathing lungs. This dependency on water means that adult amphibians generally need to stay close to moist environments to prevent dehydration. Their skin is permeable, which allows them to absorb water and oxygen, but it also makes them vulnerable to drying out. As a result, being near water is crucial for their survival.
Furthermore, water bodies provide essential habitats for breeding and raising their young. Many amphibians lay their eggs in shallow ponds or streams, where the eggs can develop safely underwater. The presence of water ensures that the eggs remain moist and can provide a suitable environment for the growing tadpoles.
In summary, amphibians live near water primarily for reproduction, developmental needs, and to maintain hydration, making it an integral part of their life cycle.
