Final answer:
Amphibians are the vertebrates that may use lungs, gills, and skin as respiratory surfaces through their life stages, from aquatic larvae with gills to land-dwelling adults with lungs and skin breathing.
Step-by-step explanation:
The vertebrate groups that may have lungs, gills, and may use skin as a respiratory surface are amphibians. Amphibians, such as frogs, salamanders, and caecilians, display a wide array of respiratory adaptations. They begin their life in water, breathing with gills like fish, and as they mature into adults, they typically lose their gills and develop lungs for breathing on land. However, their lungs are more primitive compared to those of mammals, and amphibians also rely on their moist skin for gas exchange, a process known as cutaneous respiration. It is through this process of diffusion across the skin that amphibians can supplement their oxygen intake. Other vertebrate groups like non-avian reptiles, chondrichthyans (sharks and rays), mammals, and avian reptiles (birds) have adapted different respiratory systems that do not typically include using their skin as a significant respiratory surface.
