Which of These are Amniotes

Question

Which of these are amniotes?
A)amphibians
B)fishes
C)turtles
D)lungfish

Accepted Answer

Amniotes are a group of tetrapod vertebrates that lay eggs with four membranes (the amnion, chorion, yolk sac, and allantois), which allow for reproduction in a terrestrial environment. Turtles are fully terrestrial and lay amniotic eggs, making them amniotes. Amphibians and fishes are not amniotes, as their eggs lack the necessary membranes. Lungfish are not clear-cut amniotes, as they have a mixture of traits from both amniotes and non-amniotes.
