What are the three types of amniotes?
Classifications of the amniotes have traditionally recognised three classes based on major traits and physiology:
- Class Reptilia (reptiles) Subclass Anapsida (“proto-reptiles”, possibly including turtles)
- Class Aves (birds)
- Class Mammalia (mammals)

What are the two main groups of amniotes?
There are two main divisions of amniotes, the sauropsid amniotes and the synapsid amniotes. The sauropsid amniotes include the reptiles and birds. Formally, this constitutes many different groups, but the sauropsid amniotes share many derived characteristics which separate them from the synapsids.

Which is not an Amniote?
Answer and Explanation: The animal that is NOT an amniote is A) bullfrog. Amniotes are vertebrates that are within an amnion during embryonic or fetal development. Mammals (e.g. humans), reptiles (e.g. coral snake), and birds (e.g. bald eagle) are amniotes.

What is the difference between amniotes and an amniotes?
The anamniotes are an informal group comprising the fishes and the amphibians which lay their eggs in water. They are distinguished from the amniotes (reptiles, birds and mammals), which lay their eggs on land or retain the fertilized egg within the mother.
What is the difference between amniotes and anamniotes?
Amniotes and Anamniotes are two vertebrates groups. The key difference between Amniotes and Anamniotes is that Amniotes are higher vertebrates including reptiles, birds, and mammals while anamniotes are lower vertebrates including fishes and amphibians.
