“During hibernation the frog respires through:”

"During hibernation frogs respire solely through their skin a process called cutaneous respiration. In cold conditions they enter a dormant state relying on oxygen diffusion through moist skin. This adaptation allows survival in low-oxygen environments like ponds. Cutaneous respiration reflects amphibians’ unique physiological adaptations. Understanding this process highlights the biological mechanisms enabling survival in extreme conditions contributing to studies of amphibian ecology and environmental adaptations in diverse habitats."
