i) Reptilia example: lizards

Chondrichthyes example: sharks

ii) Reptiles are cold-blooded four-legged vertebrates covered with scales. Reptiles use lungs for respiration though many of them spent most of their life in the water environment.

Chondrichthyes are marine fishes whose skeleton is composed of cartilage. The respiration occurs through gills that are not covered with a bone cover (operculum).
