Solution: Amphibians, despite being able to live on land, require water to complete their life cycle and can live in an aquatic environment. Reptiles are fully terrestrial.

Amphibians have moist, glandular skin. The skin of reptiles is usually dry, rough, non-glandular and scaly.

Both amphibians and reptiles have a bony endoskeleton. The former has a dicondylic skull while the latter has  a monocondylic skull.

Amphibians respire through their skin, gill, lungs or the lining of their oral cavity. Reptiles breathe exclusively through lungs.

Amphibians exhibit noticeable sexual dimorphism and their fertilization is external. Reptiles don’t have evident sexual dimorphism and undergo internal fertilization

Amphibians are oviparous, whereas reptiles are oviparous or ovoviviparous.

Both amphibians and reptiles have pentadactyl limbs. The former lacks claws and has modifications, eg. webbed feet in frogs. The ends of reptiles’ toes are modified into claws.
