Snakes like amphibians are included in
A. Gymnophiona
B. Anura
C. Urodela
D. None of the above.

Answer 1

Hint:This group includes the legless caecilians and all amphibians more closely related to them than to frogs or salamanders. The body is cylindrical dark brown or bluish black in color.

Complete answer:
To answer this question, first, we need to know about amphibians. Amphibians are small vertebrates that need water, or a moist environment, to survive. The species in this group include frogs, toads, salamanders, and newts. All can breathe and absorb water through their very thin skin. Amphibians also have special skin glands that produce useful proteins.
Now, let us find the solution from the option.
Gymnophiona is a group of amphibians which includes the legless caecilians. Their body resembles snakes; they live underground in humid tropical regions throughout the world. They have long, limbless, cylindrical bodies that abruptly end behind the cloaca or short tail.
Anura includes the frogs and toads that, due to their large distribution, are called by many people around the world.
Urodela is an order of amphibians that comprises the newts and salamanders, which retain the tail as adults.

Thus, the correct option is A. i.e. Gymnophiona.

Note:Gymnophiona, also called Apoda, It is one of the orders of the class Amphibia. Its individuals are called caecilians. The majority of this group is limbless, wormlike amphibians stay below ground in humid tropical regions all over the world. Because of their relatively hidden existence, caecilians are unfamiliar to the layperson and are not usually considered in discussions about amphibians.
