Solution
- Yes, fishes and frogs can respire through their skin.
- The larval stage of frog i. e. tadpole respires through gills. During metamorphosis, tadpoles lose their gills and develop lungs.
- Frogs do not have scales and breathe through their skin underwater.
- Fishes respire primarily via gills. The body of fishes is covered with scales which limits cutaneous respiration in them.
