Question

Which among the following is not a characteristic feature of amphibians?

• A. Requirement of water for reproduction
• B. Amniotic eggs
• C. Moist skin without scales
• D. Cutaneous respiration

Answer 1

The correct option is B Amniotic eggs

The amnion is a membrane that is formed around the developing embryo of many animals including the mammals. This is absent in the amphibians.

Amphibians have moist skin without the exoskeleton. They can respire with the help of this moist skin (cutaneous respiration). Amphibians require water for reproduction as they lay their eggs in water and also fertilization takes place in water. The development of the tadpole stage also takes place in water till the adult stage is reached.
