Which of These Groups of Organisms are Amniotes

Question

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

Accepted Answer

Amniotes are a group of tetrapods (four-limbed animals with backbones or spinal columns) that includes reptiles, birds, and mammals. These organisms are characterized by having an amnion during the development of the embryo. Turtles, being reptiles, fall under the category of amniotes, unlike amphibians, fishes, and lungfish, which do not have this characteristic embryonic membrane.
