Reptiles and birds produce eggs that are self-contained so far as liquids are concerned. They have hard or leathery shells that are mostly impermeable to water (although they cannot survive for long if submerged). The shells of amphibians are permeable, and must be in water at least part of the time or they will dry out, causing the embryo to die from dehydration.
