But most mammals have evolved amniotic eggs that develop inside the mother's womb, or uterus, and so lack a shell. The eggs of these species are often laid in water, which protects them from being damaged or squished. In the placental mammals the fetus, and wastes are removed. The amniotesreptiles, birds, and mammalsare distinguished from amphibians by their terrestrially adapted egg, which is protected by amniotic membranes. This makes uric acid a more water-efficient way of excreting nitrogenous wastes, versus the synapsid method. Because reptiles, birds, and mammals all have amniotic eggs, they are called amniotes.
