(at around 1 min) The opening egg hatching sequence, contains multiple errors (when compared to reptiles in general). A number of lizards and snakes develop a true tooth that is shed after use; while other reptiles and birds generally develop an analogous epidermal horn that is reabsorbed or falls off. This is because their current teeth are still in development. Fully developed claws are never used to penetrate the shell since they would be far too soft during this early development stage and due to submersion in cytoplasm (amniotic fluids). The scales on the body are also effected in the same way. Most reptiles lay amniotic eggs covered with leathery shells, with a minority featuring calcareous exteriors (hard-shells). The calcareous eggs also contain a much thicker/stronger outer membrane (when compared to bird eggs) which usually remains intact even as the shell itself cracks.
