Are lungfish amnions?
Lungfish are not amniotes; they belong to a group called dipnoi, which are a type of fish. Amniotes are vertebrates that possess an amniotic egg, a characteristic that includes reptiles, birds, and mammals. Lungfish have adaptations for breathing air and can survive in low-oxygen environments, but they do not have the amniotic structure associated with amniotes. Therefore, while lungfish are an interesting evolutionary link, they do not fit the classification of amniotes.

How does anatomy and circulation differ among amniotes?
Amniotes differ from earlier vertebrates in that they can complete their life cycle on land rather than in water. Earlier vertebrates had to have water to lay eggs at the minimum. Amniotes developed eggs with amnios which allowed the eggs to be laid on land or carried by the mother.
What is the meaning of aminiotic sac?

Are these Amniotes vertebrates House sparrow garter snake African elephant?

Why are mammals considered to be amniotes even though most mammals do not produce an amniotic egg?
Mammals are considered amniotes because they share a common ancestor with reptiles and birds, which do produce amniotic eggs. While most mammals do not lay eggs, they still develop within an amniotic sac in the uterus. The presence of extraembryonic membranes, such as the amnion, allantois, and chorion, during embryonic development in mammals is a key characteristic that aligns them with other amniotes.
Are leatherback sea turtless anphibians?
