Eggs with tough protective shells typically develop into reptiles, birds, and some mammals, such as monotremes. The hard shell provides protection against environmental hazards and predators, while also preventing desiccation and allowing for gas exchange. This adaptation enables the embryos to develop in a relatively stable environment, enhancing their chances of survival until hatching.
