Despite their multiple adaptations, amphibians are still restricted to moist environments. Which are the three main reasons for that still tie amphibians to water? External fertilization needs water Filter-feeding of suspended particles in water Gills are delicate and require the buoyancy of water to support them Eggs have no protection from dehydration Skin has to kept moist for gas exchange
