Which of the following is NOT a characteristic of Amphibia class of animals?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3, i.e. Amphibians' eyes are without eyelids.
This is NOT correct because amphibians do have eyelids. Most amphibians, like frogs and toads, have movable eyelids and a special transparent third eyelid called the nictitating membrane that protects and moistens their eyes. Therefore, saying they are "without eyelids" is factually incorrect.
