Amniotic Egg

This photo of a chicken egg is considered to be an amniotic egg. Amniotic eggs typically come from mammals, birds, and reptiles. These eggs have certain membranes that protect the embryo and remove waste. These membranes are called extraembryonic membranes. Although this egg is used for cooking, if it had developed fully, the embryo inside of it would've been supplied with oxygen, food, and water from the extraembryonic membrane.
