Question

Animals like ghariyal and crocodile live in water as well as on land. Are they amphibians or reptiles?

Answer 1

1. Ghariyal and crocodile are reptiles. They are capable of swimming in water and crawling on land. However, they can only respire with the assistance of lungs. Their respiration occurs via the nostrils.
2. Even while submerged, they must surface to inhale and expel air.
3. Amphibians can respire through their skin in aquatic environments and use lungs in terrestrial settings.
4. They possess a rigid exoskeleton, which amphibians lack.

Therefore, ghariyal and crocodile are not amphibians; rather, they are reptiles.
